Front Office Python Developer (Prop Trading Firm) London | Hybrid | Trading Technology A leading digital asset trading firm is looking for a Front Office Python Developer to join its London team, working at the heart of the front office alongside traders and quants. This is a hands-on role in a small, high-impact team, focused on building and scaling the systems that directly support trading, decision-making, and data flow across the business. What you’ll be doing: • Design and build core trading systems used in day-to-day trading activity, • Work closely with traders to develop tools that improve execution, monitoring, and performance, • Develop real-time systems and data pipelines to capture and process trading activity across multiple venues, • Contribute to trade capture, reconciliation, and position-keeping systems, • Build internal tooling and infrastructure supporting data analysis and ML workflows, • Take ownership of projects from concept through to production What we’re looking for: • Strong experience with Python (Python 3), • Experience building real-time systems, data pipelines, or backend services, • Solid understanding of SQL/databases, • Comfortable working in Linux environments, • Interest in trading, crypto, or financial systems

The pitch. It’s a serious engineering role with a great team – and meaningful responsibility. This is not a narrow “ticket-closing” developer job. You won’t be handed tightly scoped Jira tasks inside a heavily layered team structure. You won’t be maintaining a disposable MVP. And you won’t be managing people. Instead, you’ll be working on the core platform that underpins Outsmart’s crowdsourcing operations – a mature, revenue-generating system that has evolved over years and continues to scale. If you enjoy owning real systems, thinking architecturally, improving legacy code thoughtfully rather than rewriting it, and being trusted to deliver without heavy supervision, this role will feel unusually well-matched. The role As Senior Fullstack Software Engineer, you will help design, build and maintain the production systems that power Outsmart’s platform. You’ll work closely with our CTO, operating as a high-agency individual contributor with genuine ownership across backend systems, infrastructure and platform evolution. This is a role for someone who wants to: • Work on real, live systems with meaningful operational responsibility, • Make architectural decisions, not just implement them, • Improve and extend an existing platform with care and judgement, • Help shape the engineering foundations for the next stage of company growth You will be trusted to take product and operational requirements and translate them into robust, production-ready solutions. What you’ll be doing • Designing and maintaining backend services primarily in Python, • Developing and evolving well-structured RESTful APIs, • Designing and improving data models across relational (e.g. PostgreSQL) and NoSQL databases, • Working across the stack where needed, including JavaScript, modern HTML/CSS, and utility frameworks such as Tailwind, • Contributing to cloud-based infrastructure (e.g. Google Cloud), deployment pipelines and DevOps practices, • Debugging live production issues with a calm, root-cause mindset, • Incrementally improving system architecture using sound design principles (including modular design, DDD-style thinking, and pragmatic architectural patterns), • Reviewing code, raising standards constructively, and contributing to a disciplined engineering culture, • Leveraging modern tooling (including AI-assisted development) to improve quality and velocity This is not greenfield experimentation. It is thoughtful, high-quality engineering on systems that matter. The environment We are a small, intellectually serious company. That has advantages and responsibilities. You will: • Speak directly with senior decision-makers when needed, • Operate without perfect documentation, • Balance speed with long-term maintainability This role suits someone comfortable with autonomy, accountability and cross-functional collaboration. Who this role is for This role is designed for someone who is: • 8–15 years into their engineering career, • Has worked in a small company (c. 5–30 people) or similarly lean environment without heavy process, • Experienced in inheriting and improving mature systems, • Comfortable reading and navigating complex legacy code, • Strong in systems thinking (trade-offs, scalability, cost implications), • Backend-heavy, with strong Python expertise, • Operationally mature – you’ve supported production systems, not just built features You are likely: • Calm under pressure, • Direct but not ego-driven, • Curious and thoughtful rather than dogmatic, • Comfortable challenging ideas constructively If you primarily identify as a manager, a greenfield-only builder, or someone who prefers heavy structure and layered sign-off, this role is unlikely to be a good fit. Practicalities Schedule: Monday to Friday Weekends: No Location: UK-based Working style: Hybrid (remote and London office) Why Outsmart Insight? Outsmart Insight operates at the intersection of technology, intelligence and large-scale coordination. Our internal platform powers a global network and supports complex, high-trust client engagements. We are deliberately serious about quality, reliability and long-term thinking. As we grow, we are investing in strengthening our engineering foundations – building systems that are robust, scalable and thoughtfully designed.

About Our Client We're representing a company on a mission to redefine how modern distributed systems are tested and released. Their platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility — and it exists because developers deserve something better than what's out there. If you've ever lived through a production outage, had a brutal on-call week, or watched a release slip by weeks because of one killer bug — you'll understand exactly why our client built what they built. If you're passionate about developer-first products, system resilience, and correctness, keep reading. The Role Our client isn't looking for a typical SE. They want an unconventional thinker — someone who gets genuinely energized by breaking things, thrives on chaos, and has the technical chops to deploy a sophisticated testing platform against real-world software and make it sing. You'll split your time between hands-on POC work, customer-facing technical conversations, and thought leadership around a testing paradigm that most engineering teams haven't encountered yet. You'll be the person in the room who actually understands what's happening under the hood — and can make a skeptical senior engineer a believer. What you'll do: • Execute POC engagements that demonstrate real product value to prospective customers, • Lead customer workshops on Property-Based Testing (PBT) and related methodologies, • Support the sales team with technical qualification and consultation, • Find bugs. Break open source software. Make a point of it., • Build, maintain, and deliver product demos that land with technical audiences, • Guide customers and prospects on platform adoption and testing best practices, • Participate in new customer onboarding and early-stage success, • Highly technical — and more importantly, technically curious, • Easily bored; you need new problems to stay engaged, • A natural communicator who can translate complexity for both engineers and executives, • Comfortable under pressure and in tight timelines, • Professional enough for enterprise clients, flexible enough for a fast-moving startup, • Hands-on experience building and running automated tests (integration, end-to-end), • Containerization: Docker, Kubernetes, • Object-oriented programming fundamentals, • Linux-based operating systems, • Scripting: Bash/Shell, Python, or JavaScript, • Data querying: SQL, NoSQL, or equivalent This role requires some travel — client sites, conferences, and occasional visits to our client's HQ. If that's your thing, all the better. Why It's Worth a Look Most SE roles are demo-and-support. This one is different. Our client is building a new category, and the SE who joins now will have outsized influence on how that story gets told technically — and how customers succeed with a platform that genuinely does something new.

At Aries Global, we're driven by a singular ambition - to build one of the world's truly exceptional software groups. A high-performing culture where we're able to deliver transformative value to our group, and a place where every team member can demonstrate autonomous impact in a highly collaborative environment . Our mission is simple: we don't just acquire companies - we build enduring, AI-native software platforms. We partner with founders who have built great products and help them unlock their next chapter through our AI-native operating system, centralised GTM engine, and world-class execution capabilities. We bring together exceptional operators, product builders, and leaders - people who insist on the highest standards and excel in a culture of fast pace, focused execution, and deep ownership. In return, you'll experience extraordinary growth, meaningful impact from day one, and a career trajectory far steeper than you thought possible. The Role You will build production systems that matter. Not tickets. Not side projects. Core product. We're hiring at all levels: from early-career engineers to seasoned technical leaders. What matters is how you think, build, and ship. You'll take end-to-end ownership of features from architecture design to measurable impact — shipping code that directly moves revenue, retention, or product velocity. You'll design clean abstractions in ambiguous environments, evolve systems into scalable AI-native platforms, and make strong trade-offs between velocity and durability. • If you're backend-leaning: You'll use Ruby, Python, TypeScript to build and improve a high-performance platform — designing APIs, data models, and integrations that scale., • If you're frontend-leaning: You'll use React and TypeScript to build smooth user experiences that handle real-time data. Either way, you'll collaborate directly with product and commercial teams to shape what gets built, not just how. We care about outcomes, not activity. What We're Looking For • You've built and shipped real systems. You understand data modelling, API design, system trade-offs, testing, and reliability. You know how to move fast without creating chaos. You're strong in at least one modern stack — full-stack ability is a big plus., • You think fast and communicate clearly. You form mental models quickly, break down ambiguous problems, prioritise high-leverage work, and explain your reasoning concisely. You may come from a startup, a top-tier engineering team, or an analytically rigorous environment., • You own the outcome. You don't wait to be told what to do. You don't hide behind ambiguity. You care about the result — and you act on it., • You're AI-native. You're actively exploring LLM workflows, AI tooling, automation, or developer productivity improvements. You see AI as a force multiplier, not a buzzword. Culture High standards. Low ego. Direct feedback. Fast execution. Real accountability. We value people who care deeply about the craft and the outcome. Why Aries • Work alongside unusually driven operators and builders, • Real ownership from day one, • Exposure to multiple software platforms and business models

A trading team generating over $1 billion in annual PnL at one of the world's most established quant trading firms has tasked us with finding a Senior Quantitative Developer for their London research team. This isn't a central infra role. You'd be sitting inside the team itself, owning the research and backtesting framework that their quants use every day to develop and refine live strategies. Direct PnL impact. You see it. You feel it in your comp. At the biggest shops in this space, you can spend years building tools that never get near a live strategy. This is the opposite of that. What you'd be doing: → Own and iterate on the simulation and backtesting framework → Build Python tooling used daily by on-site quant researchers → Monitor and maintain research jobs in production → Collaborate with a global research team on live strategy development What they want: → Production-grade Python, strong with statistical libraries → Sharp problem solver, comfortable moving fast in a collaborative environment → C++ or scripting a plus, not a requirement → Someone who genuinely wants to be close to the trading Comp is market-leading for prop trading and reflects exactly how close you are to the PnL.
