Senior Python Engineer

Senior Python Engineer (Fully Remote, UK)

Salary: £80,000 to £90,000

Contract: Permanent

Location: Fully remote (UK) with optional in-person sessions in Leeds

The Role

We're hiring two Senior Python Engineers to join a mature, product-led SaaS business that operates at the intersection of large-scale data, search, and compliance-critical systems.

This is a hands-on engineering role for someone who enjoys solving complex backend problems, working with real production data at scale, and contributing to the evolution of an established platform rather than a proof-of-concept.

The team is currently undertaking a major re-architecture and rewrite of its core product, moving from an initial version to a more scalable, robust, and future-proof platform. You'll be joining at a point where your technical input will genuinely shape how the system evolves.

What You'll Be Working On

• Building and maintaining Python-based backend services
• Developing APIs within a Flask-based backend
• Working with PostgreSQL for persistence and Elasticsearch for indexing and search
• Contributing to a wider v1 → v2 product rewrite, focusing on scalability, performance, and reliability
• Collaborating closely with other senior engineers to make pragmatic, production-ready engineering decisions

This is not a people-management role. It's for engineers who want to stay deeply technical and have real ownership over what they build.

The Tech Environment

• Python
• Flask
• PostgreSQL
• Elasticsearch
• Kubernetes (as a runtime environment rather than a DevOps-heavy remit)

What They're Looking For

• Strong commercial experience as a Senior Python Engineer
• Proven background building and maintaining backend APIs
• Solid software engineering fundamentals and experience working on complex backend systems
• Comfortable working autonomously and taking ownership of delivery
• Clear communicator who can explain technical work, make sensible trade-offs, and estimate effort realistically
• Experience with search, indexing, or data-heavy systems is a strong plus

Working Style & Culture

• Fully remote-first across the UK
• Optional in-person sessions in Leeds for those who enjoy face-to-face collaboration
• Pragmatic, delivery-focused engineering culture
• Strong emphasis on clear communication, accountability, and reliability

Salary & Benefits

• £80,000 to £90,000, depending on experience
• Permanent role
• Fully remote within the UK
• Opportunity to work on meaningful, technically challenging systems with real-world impact
