Staff Engineer - Backend (Fully Remote)

Location: Fully Remote (UK only)
Level: Staff / Principal
Type: Permanent

The Opportunity

We’re partnering with a well-funded, product-led technology company building advanced backend systems to solve problems that traditional automation has never been able to crack.

This is not incremental engineering.

You’ll be joining a senior, highly capable engineering team that has already shipped a complex production platform and is now scaling it to handle extreme concurrency, massive data volumes, and highly sophisticated workflows.

If you enjoy designing systems that need to be fast, resilient, and correct at scale, this is the sort of role that doesn’t come around often.

What You’ll Be Doing

Designing and evolving the core backend architecture of a complex, high-throughput platform

Solving hard scaling problems across concurrency, performance, and reliability

Building systems that process large volumes of unstructured data with strict latency requirements

Setting technical direction and raising engineering standards across a senior team

Leading architectural decisions that will underpin the platform for years to come

Working closely with product and domain experts to translate real-world complexity into elegant technical solutions

This is a hands-on architecture role, not a people-management position.

What We’re Looking For

This role is aimed at engineers who have already “been there” technically.

Core experience:

Extensive backend engineering experience (typically 10+ years)

Expert-level Python, with deep understanding of async patterns and performance optimisation

Proven experience designing and scaling distributed systems

Strong background in API design, data-intensive systems, and service architecture

Track record of building platforms that operate reliably under heavy load

Nice to have:

Experience with TypeScript / Node.js in complex systems

Exposure to AI-driven platforms, document processing, or workflow engines

Experience in regulated or high-reliability environments

Cloud-native architectures and containerised deployments

What’s On Offer

Competitive base salary aligned to Staff-level impact

Meaningful equity in a fast-scaling business

Flexible PTO

Pension contribution

Fully remote working setup

If you’re a Staff-level backend engineer who enjoys solving problems most teams never even attempt, this is one worth exploring.
