We’re particularly interested in hearing from people who have built polished consumer experiences, thrive in startup environments, and want to help create something category-defining. Why Join Us: • 25 days of annual leave, plus public holidays in England and Wales, • A fast-growing, mission-driven startup at an early stage and a product that directly impacts consumers in a meaningful way, • High ownership, autonomy, and direct impact on the product and customer experience, • A collaborative, ambitious team of scientists, engineers, and operators building something genuinely new, • Strong in-person/hybrid culture, fast feedback loops, and zero bureaucracy, • Backing from world-class investors, • A fast-moving environment where great ideas can quickly become reality, • Opportunity to shape both the product and engineering culture from the ground up Interview Process • 30 minute screen with Talent Acquisition, • 1 hour meeting with the Engineering Team, • 45 minute meeting with the Data Team How to Apply Please submit: • Your CV, • A short cover letter explaining why you’re interested in Mitra Bio and what excites you about this role Diversity, Equity, and Inclusion At Mitra Bio, we believe the best ideas, products, and breakthroughs come from diverse perspectives and lived experiences.

Data Engineer - Investment Platform £90k–£140k + bonus + benefits Hybrid | Central London There's a quiet data problem at the heart of private markets and a London fintech is building the infrastructure to solve it. Every PE fund, credit strategy and infrastructure vehicle reports NAVs, capital calls and investor positions differently. Different fund admins. Different formats. Different cadences. Some APIs are terrible. Many don't exist at all. Now imagine giving a wealth manager in Zurich, a private bank in Hong Kong and an adviser in Sydney one clean, regulator-ready view across all of it - in near real time. That's the challenge that we need a software & data engineer to solve. You'll own ingestion pipelines from global fund administrators, design scalable data models across relational, NoSQL and Delta architectures, and solve the reconciliation problems that turn fragmented investment data into a clean, unified layer the platform can rely on. You'll also help shape how AI gets embedded into the platform - not as a side experiment, but as core infrastructure. The engineering environment is modern and evolving fast. You get room to shape systems, not just maintain them. Python and Azure underpin a modern distributed data platform built around ingestion pipelines, lakehouse architecture, streaming workflows, Databricks, CI/CD, observability and product-facing data services. The team is actively pushing further into AI-native workflows - using LLMs to improve ingestion, reconciliation and reporting, while investing heavily in data quality, lineage and platform reliability. The wider application stack is React, TypeScript and Node, so this isn't a siloed data engineer role hidden away from the product. Engineers here work across the platform where it makes sense: infrastructure, pipelines, APIs, application architecture and the data experiences exposed to end users. Engineering culture matters too. Leadership comes from deep trading-tech and asset management infrastructure backgrounds. Pragmatic people. Low ego. Strong technical standards. The kind of environment where good architectural pushback is welcomed. You'll enjoy logging every morning if: • Care deeply about data quality and clean engineering, • Enjoy solving messy, high-consequence data problems, • Like operating across data, infrastructure and application engineering, • Want ownership, not endless Jira ticket throughput, • Are curious about fintech, wealth or private markets, • See AI as an opportunity to build better systems, not just automate tasks You don't need prior private markets experience. What matters is strong engineering judgement, deep Python capability and the ability to navigate messy, real-world data problems without overengineering them. Curious to know more? Hit apply or send me a DM — informal first conversations are taking place now.

The moment Consulting is being agentified. The $300B insights industry is about to be rebuilt by AI agents that don't just report what happened — they tell brands what to do next and execute it. Most firms are still figuring out how to use ChatGPT for email. We've already built the agents. Hotspex has spent 25 years measuring what the world's biggest brands make people feel — over 1M interviews, 800+ brands, 33 countries, validated at P&G, Coca-Cola, Unilever, RBC, TELUS. Now we're weaponizing that dataset with AI. Every methodology we've built is becoming an autonomous agent. Every deliverable is becoming a living product. Every client interaction is becoming an intelligent system. This is the Agentification of Consulting — and we're riding the front of the wave. We need a Full Stack Engineer in Toronto who wants to build what comes next. What you'll build You won't be maintaining someone else's codebase.

You can go from a rough CEO brief on Monday to a shipped product by Friday. Specifically: • Full-stack fluency — React, Node, Python, modern deployment (Vercel/Netlify, Supabase, serverless). You own the whole surface from UI to infrastructure, • AI-native — you've built with Anthropic and OpenAI APIs, you understand tool use, embeddings, MCP, and agentic workflows. You don't just prompt — you architect systems around LLMs, • Claude Code proficiency is essential — we build with it daily and we'll want to see examples of what you've shipped with it, • Genuinely interested in marketing and brand strategy — you want to understand why a campaign moves a brand, not just render the dashboard. The best code at Hotspex is written by people who understand the business problem, • Product-minded — you think in user outcomes, not tickets. You push back on bad specs and propose better solutions, • High ownership, low ego — direct access to the CEO, the IP, and the clients means you'll have outsized impact and outsized accountability Why this role is rare 💰 Stock options — you'll have equity upside in a company that's been profitable for 25 years and is now scaling its AI product suite into a category-defining SaaS business 🏢 Toronto-based, on-site — we believe the best products get built by people in the same room solving hard problems together. Being in Toronto is key — this is a hands-on, high-trust, high-speed environment 🚀 Fortune 100 clients from day one — your code ships to RBC, global CPG, major broadcasters, and government. Not a pre-revenue pitch deck 🤖 AI isn't a feature — it's the entire product thesis — every tool, methodology, and deliverable at Hotspex is being agentified. You'll be at the centre of that transformation 📐 25 years of proprietary IP — you're not starting from zero. You're building on top of the Human Motivation Framework — 177 personality attributes, 96 emotions, 8 motivational zones — a dataset most AI startups would kill for 🎯 No four-layer product org — you'll work directly with the CEO, strategists, and clients. Your decisions ship Qualifications • Proficient in front-end development: HTML, CSS, and modern JavaScript frameworks (React preferred), • Skilled in back-end development: server-side languages, database management, API design, • Proven full-stack delivery — end-to-end ownership from architecture to deployment, • Strong experience with Claude Code — show us what you've built with it, • Familiarity with cloud platforms, DevOps tooling, and CI/CD pipelines, • Experience with agile workflows and Git-based version control, • Excellent problem-solving instincts with a bias toward performance and scalability, • Strong communication skills — you'll present to clients, not just commit to repos, • Bachelor's degree in Computer Science, Software Engineering, or related field preferred — but shipped work matters more than credentials How to apply Send a short note and your best work to — GitHub repos, shipped products, side projects, agent builds.
