We’re building financial infrastructure from scratch. We’re looking for a Lead Engineer who wants to build the spine of a transactional system — the part that must be right every single time. Someone who thinks about ordering, consistency, idempotency, throughput, latency, and the quiet mechanics of how systems fail and recover. This is systems engineering, not app building. This is a founding-team role. You’ll decide how the whole thing is shaped: the architecture, the tools, the patterns, the early hires. You won’t just write code; you’ll define the foundation the rest of the system stands on. What you’ll do (subject to change) • Build the core transactional engine, • Shape and implement the internal ledger: how value is recorded, moved, reconciled, and audited., • Choose a sensible, durable tech stack. We’re stack-agnostic: good engineers know how to pick the right tools., • Ship early versions quickly, then turn them into reliable, observable, production-ready systems., • Think and make decisions about load, ordering, concurrency, latency, failure modes, and keeping the system steady under pressure., • Design components that behave well when things go wrong, not just when things go right., • Work directly with product to turn rough ideas into concrete, buildable designs., • Help translate technical decisions into something regulators and compliance teams can understand and approve (clarity matters as much as code)., • Set the engineering culture: clear thinking, clean boundaries, solid tradeoffs., • Hire and mentor the early engineering team., • Build parts of the system that may later connect to digital forms of value (tokenized assets, programmable money, etc.), though no prior blockchain experience is required. What you’ve done (or know how to do) We’re not counting years. We care about whether you’ve built and scaled real systems. You might have: • Designed or maintained backend systems where correctness mattered, • Worked on or built out ledger-like systems: balances, movements, reconciliation, states that must always add up, • Built or maintained systems in payments, financial engineering, neobanking, or digital banking (helpful, but not required), • Taken something from zero → v1 → something that actually had to scale, • Worked on infrastructure where ordering, reliability, and recovery weren’t optional, • Dealt with concurrency, race conditions, and real-world load, • Worked in small teams where responsibility wasn’t shared, you owned it How we work We’re a small and hands-on team. We value clarity, long-term thinking, and written reasoning. We avoid unnecessary complexity and focus on the problems that matter. We’re building something that will sit in a regulated environment, so discipline, transparency, and careful design are critical to the work, not just afterthoughts. There’s no map for what we’re building. You should be comfortable drawing it. What we offer • A founding role shaping a long-term, high-impact system, • Real ownership and autonomy, • Competitive compensation, • The chance to build foundational financial infrastructure from the ground up

Our values: Ambition. Humility. Care. We're fixing fashion's $300 billion fit problem - before clothes are even made. 71% of returns are fit-related, generating 4 billion pounds of textile waste annually and contributing to <10% of global carbon emissions. We use AI and data science to help fashion brands get the cut right in production, preventing returns and waste at the source rather than just predicting them. Our platform acts as an AI co-pilot for buying and production teams, turning 30 years of fashion expertise into data-backed decisions. Founded by Phoebe Gormley, we've just closed the UK's largest female-founded pre-seed ($4m) led by Albion and SuperSeed, setting us up to build the team and product that will fix fashion's fit problem.

Working alongside a cross-functional data and engineering team you’ll contribute to key product initiatives, including: • Customer-facing web app: Develop the interface that surfaces actionable insights to buying and production teams at the right moment, • AI pre-production co-pilot: Build the next-generation product that guides designers through the creation process, preventing fit issues before garments are made, • Customer onboarding platform: Allow our customers connect their systems (PLMs, Shopify, returns data) to our platform through a guided, self-service flow, • AI-powered features: Working alongside our data team, you'll build the interfaces that surface predictions and insights to users, • E-commerce integrations: Create plugins that inject personalized size recommendations directly into product pages in real-time. Your work will directly impact returns, revenue, and waste for major fashion brands. Our tech stack: • Languages: TypeScript, JavaScript, Python, • Frontend: React, • Backend: FastAPI, Cube.dev, • Database: Postgres, Snowflake, • Cloud & Infrastructure: Docker, AWS (ECS/ECR, Lambda, RDS, S3, Cloudfront, etc.), • Cache & Search: Redis (ElastiCache), Elasticsearch (AWS OpenSearch) What We’re Looking For: Must-haves: • 3+ years software engineering experience: ideally with TypeScript and Python, in production environments, • Frontend expertise: Strong React skills - you can build responsive, polished interfaces that users love, • Backend fundamentals: Experience building APIs (FastAPI or similar) and working with relational databases, • Cloud-native mindset: You've deployed and maintained production systems on AWS (or similar) and understand how to build for scale, • Startup DNA: You've either worked at an early-stage company or built and shipped side projects from scratch that people actually use.
