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
