Senior Software Engineer

🚀 About BorderlessAt Borderless, we’re building a world where borders are no longer barriers – where anyone can move anywhere, seamlessly and safely. Founded in 2023, we’ve already helped 600+ UK businesses and 15,000+ individuals navigate the complexity of immigration. Powered by technology, and supported by an expert team, our platform removes the friction of Home Office compliance, visa processing and sponsor licence applications, making immigration faster, simpler and more accessible for everyone. Backed by Entrepreneur First and Backed.VC, we’re scaling fast and in 2026 expanding into new sectors and markets to further accelerate our growth. 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.

What You’ll Do

• Build our core immigration platform for candidates, businesses, and our own internal teams
• Write clean, scalable, well‑documented code in TypeScript, React, and SQL
• Design and maintain complex data models for performance and extensibility
• Collaborate cross‑functionally across the whole company: Product, Ops, CS, Sales, and Engineering
• Identify and resolve platform bottlenecks, technical debt, and stability issues
• 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

You should apply if

• You’re a proactive problem‑solver who enjoys collaborative work across multiple functions
• You have strong experience building full‑stack web applications
• You think deeply about the structure and performance of web applications, and when to apply tradeoffs
• You’re excited by the opportunity to shape the foundation of a growing product, team, and company
• You want to grow with the business — this is a high‑impact role with scope to move into tech leadership as we scale
• You’re excited about the way AI and LLMs are changing how software is written

Tech stack

• Typescript / Node
• React (NextJS)
• PostgreSQL
• AWS (Lambdas, CDK)

Interview process

• 30m screening call with Talent
• 1h interview with Director of Engineering
• 1h technical interview with one of the team (pair programming task, no take home)
