About Borderless
We believe in a world where borders are no longer barriers. Since launching in 2023, we’ve helped 400+ UK businesses and thousands of individuals across healthcare, construction, finance, and more. Our digital platform streamlines the UK sponsorship process using automation and expert support.
Backed by Entrepreneur First and Backed.VC, we’re scaling fast — and engineering is core to our ability to deliver.
Role: Senior Software Engineer
We're hiring a Senior Software Engineer to help us evolve the Borderless platform. This is a hands-on role where you’ll be writing clean, scalable code while contributing to major rebuild efforts and long-term engineering projects.
You'll work closely with our Engineering Manager, Product, and the wider cross-functional team to improve platform performance, reliability, and design. This role is essential to unlocking team velocity and addressing key technical constraints as we scale.

- Write clean, scalable, well-documented code in TypeScript, React, and SQL
- Design and maintain complex data models for performance and extensibility
- Collaborate cross-functionally with Product, Ops, CS, and Engineering
- Identify and resolve platform bottlenecks, technical debt, and stability issues
- Contribute to architectural and data design decisions
Requirements
- You have strong experience building full-stack web applications in TypeScript and React
- You’ve worked with large-scale, complex relational databases and understand trade-offs around normalisation, query efficiency, and data design patterns
- You think deeply about the structure and performance of data (data access vs data query trade-offs)
- You’re a proactive problem-solver who enjoys collaborative work across multiple functions
- You’re excited by the opportunity to shape the foundation of a growing product and team
- You want to grow with the business — this is a high-impact role with scope to move into tech leadership as we scale
