Senior Software Engineer

Who you are

• Experience: 8+ years, including a track record of shipping production systems
• Back-end experience - ideally Node.js/TypeScript in a production API context and comfortable reading across other languages (C#, Python)
• Solid grasp of distributed systems fundamentals: async queues, event-driven workflows
• Track record of hiring and growing engineerings
• Comfortable in a startup environment where you’re building the process alongside the product
• Experience with LLM/RAG pipelines in production (embeddings, vector search, retrieval quality measurement)
• Familiarity with Autodesk Platform Services / AEC data formats (IFC, Revit, ETABS, SAFE, or similar)
• Experience with Windows desktop application development (.NET / WPF / native integrations)
• Background in construction, structural engineering software, or document-intensive vertical SaaS
• Knowledge of graph-based data models, entity resolution, or knowledge graph tooling
• Having said that, don’t worry too much about having experience with the specific tech stack - we are generally looking for people with strong core engineering skills and principles. The team are polyglots who believe specific technologies are just tools for tackling problems

What the job involves

• Tech Stack: React, Typescript, Python, C#, Azure
• You'll be one of the first engineering hires
• You'll work directly with the founders across the full stack: a Node/TypeScript backend API, a React frontend, a C#/WPF Windows desktop connector, and Python ML/RAG workers
• The codebase is in production and serves paying customers
• You'll own significant parts of it, drive the architecture of the entity-resolution layer that everything else depends on, develop contracts between our services and eventually help hire and mentor the team that grows around you
• This is an early role at a really exciting company with everything that implies - equity, influence over the technical direction, and the kind of hard problems that don't exist at bigger companies
• Ship features across the full stack. The platform is polyglot by design - you don't need to be expert in every layer, but you need to be comfortable moving across them
• Strong in at least one of (but comfortable reading the other):
• Node.js/TypeScript backend
• Python async/ML pipelines
• Experience designing and evolving APIs and async event-driven systems (queues, workers, content-addressed storage)
• The instinct to keep things simple under pressure
• Comfortable having high ownership and autonomy
• This is a very hands-on, delivery-focused role in a start-up environment. Because of this, there are always times when we need to come up with a short-term tactical solution to deliver something a little quicker than we would like. You will have a strong focus on code quality but also on flexibility and pragmatically paying off tech debt
• We believe passionately in thorough automated testing so, whilst we don’t necessarily care about strict TDD practice (i.e tests DRIVING the development - written first), every PR must have the appropriate E2E tests, unit tests or eval harnesses. We own and have responsibility for the entire platform - its deployment and its reliability - so we also completely control our own CI and CD processes
• The team is an autonomous and empowered multi-disciplinary one
• Good communication skills - we are constantly communicating in very technical language to each other one minute; semi-technical language to (for e.g) the product manager the next; and in layman’s terms to non-technical people the next. We value clarity above speed
• Strong core engineering skills - we are generally looking for strong engineers with experience building reliable systems and taking responsibility for them, not necessarily people with a lot of (or any!) experience in our specific tech stack
• Kindness, curiosity, optimism & drive - we, as a team and as a company, believe in being kind over being nice. We are constantly giving and receiving constructive feedback and we are always trying to be empathetic. We’re all growing together and on a mission to create something bigger than ourselves that will leave a mark. We have to be optimistic when we hit inevitable roadblocks, curious about everything, and driven to be at the forefront of creating new products and change

The application process

• We have a culture of respecting people’s time and we know you’ll have loads of other options, therefore we have a quick turnaround time and will let you know as soon as we can after each stage
• Ask ANYTHING. The whole process is as much about making sure we’re a fit for you as much as the other way around
• Initial screening call (5 mins)
• Call with the VP of Engineering where you’ll show us some of your code (30 mins)
• Pair with and get to know a member of our engineering team (1 - 2 hours)
• Reference checks + offer
