Senior Software Engineer
🚀 About Borderless
Borderless is simplifying the complexity of global immigration, starting with the UK.
Immigration is one of the most important - and most broken - systems in the global economy. It’s shaped human history, yet businesses and individuals hit friction at every turn, and government policy lurches with the political cycle.
Our vision is simple: a world where borders are no longer barriers, empowering the ambitious, wherever they are.
Backed by Entrepreneur First and Backed.VC, we’re already supporting 600+ businesses, 15,000+ workers and scaling fast into new sectors and markets.
Around 25% of our workforce is sponsored, and we proudly offer visa sponsorship as part of our hiring process.
🎯 Role: Senior Software Engineer
We're hiring a Senior Software Engineer to help us build the Borderless platform. This is a hands-on role where you’ll be writing clean, scalable code while building our core immigration product.
You'll work closely with our Engineering Director, Head of Product, and the wider cross-functional team to understand the needs of our customers and solve their problems. We deploy our platform > 10 times per day, and rapidly review and iterate on feedback.
This role requires working in the office 3 days per week. If this is not possible for you, please do not apply.

- Contribute to architectural and data design decisions
📈 What we’ve done recently
- Built an automatic document classifier (using a combination of AI and LLMs) – customers can bulk upload any visa-related document (e.g. payslips, passports), and we’ll securely store, categorise, assign, and extract the documents to their workforce
- Introduced a queuing platform (SQS) for various parts of the application, to control asynchronous workloads
- Run an LLM-driven security audit on our existing codebase ahead of our next pen test
