LineTen is on a mission to crack the code on urban delivery. By leading with our values and putting carrier partners first, we are paving the way for better delivery experiences. LineTen is a new approach to delivery with a free carrier API and an operations management platform for shippers. We're building the first global data‑driven last‑mile network that has the potential to solve industry‑wide problems.
We’re hiring a Senior Software Engineer who treats software as a craft, not a checklist. You’ll join a small, high‑trust team where ownership is expected, curiosity is encouraged, and outcomes matter more than activity. This is not a ticket‑factory role: you’ll be expected to think critically, challenge assumptions, design robust solutions, and take responsibility for their long‑term success. You’ll work across backend services, distributed systems and frontend integrations, with a strong focus on correctness, maintainability and architectural clarity. You’ll also use AI‑assisted development tools responsibly, understanding that speed only matters when paired with strong design, testing and review discipline.
How you’ll work
- Operate with high ownership in a low‑process environment
- Proactively look for what can be improved rather than waiting for direction
- Value correctness, clarity and maintainability over “it just works”
- Work outside strict role boundaries when needed, without feeding burnout culture
- Communicate technical decisions clearly and push back constructively when required
Core technical skills
- C# / .NET 8+, Entity Framework Core, async/await, MediatR / CQRS
- Strong understanding of distributed systems: consistency models, event‑driven patterns, idempotency, race conditions
- Experience with Redis caching, Azure Blob Storage, and data‑modelling trade‑offs
- API design: RESTful contracts, versioning, webhooks, long‑running operations (202 Accepted patterns)
- Real‑time & frontend integration: SignalR / WebSockets, SPA frameworks (Vue / Nuxt or similar), TypeScript
What good looks like
- You leave systems clearer, more correct, and easier to evolve
- Problems are solved at the right level, not patched over
- Trade‑offs are explicit and understood
- Other engineers trust your judgement and the quality of your code
