Senior Software Engineer

Location: London (flexible working with 3 days per week regularly expected in office)

Job Type: Full-time

Salary & equity: £100k+

Tech Stack: React, Typescript, Python, C#, Azure

Must-Haves:

• 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.

Structural engineering firms need effective design change management to avoid costly delays and manual design change propagation.

Structural engineers work across a fragmented ecosystem of tools with no shared source of truth - ETABS models, SAFE analyses, Autodesk drawings, Excel specs, PDFs, emails.

Bite is building an effective automated design change management product for structural engineering firms preventing costly delays, manual design change propagation, and errors.

Our platform does two things that today require weeks of manual work: natural-language search across a project's entire file ecosystem, and cross-file impact detection ("I changed Column C7 in the structural model - what drawings, schedules, and specs are now out of date?"). Both are powered by a single underlying engineering-knowledge graph built on content-addressed file storage, per-file structured extraction, and a canonical entity resolver that unifies concepts across file formats.

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.

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

• 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.
