We’re supporting a fast-scaling, globally distributed tech business that is evolving its backend architecture and investing heavily in performance, scalability, and long-term platform direction.
They’re looking for a Senior Backend Contractor with strong Java and/or Rust experience to help shape and build the next generation of backend services. Rust is particularly relevant to where the platform is heading, though Java remains important. On the frontend, the team works with React, and there is existing exposure to Ruby and Python, where a working, mid-level understanding is beneficial rather than core.
This is a high-impact, long-term contract within an experienced engineering team, ideal for a contractor who enjoys working close to product and infrastructure while influencing technical direction.
What You’ll Be Doing
- Designing and building high-performance backend services using Java and/or Rust
- Contributing to architectural decisions as the platform evolves toward more systems-level and performance-focused solutions
- Working alongside frontend engineers using React to deliver end-to-end features
- Supporting and integrating with existing services written in Ruby and Python
- Collaborating with product, platform, and infrastructure teams to scale critical systems
- Driving best practices around clean architecture, performance, reliability, and security
Core Skills & Experience
- Senior-level backend engineering experience in Java and/or Rust (production systems)
- Strong understanding of scalable backend architecture, APIs, and distributed systems
- Experience working in cloud-native environments
- Contractor mindset: able to onboard quickly, communicate clearly, and deliver value fast
Strongly Preferred
- Commercial experience with Rust, or a clear desire to work more deeply with it
- Experience working alongside React frontend teams (hands-on or close collaboration)
Nice to Have
- Mid-level exposure to Ruby or Python (not required to be expert-level)
- Experience working on systems at scale or within high-growth environments
Contract Details
- Contract Type: LTD Company (UK) / B2B
- Location: Fully remote (EU-based required for legal and timezone reasons)
- Duration: 12 months, with strong extension potential
- Start Date: ASAP
