Python Architect – London (Onsite, Full-time)
Competitive Salary + Bonus
We’re working with a high-performing global investment firm that’s rebuilding its technology foundations — and they’re looking for a Python Architect to help design and deliver the systems that power their research, data, and risk functions.
This is a chance to join a small, elite engineering team where ideas move fast, ownership is real, and your work directly impacts performance.
What You’ll Do
* Design, build and maintain backend APIs and automation tools used across research, data, and operations.
* Develop scalable data flows and microservices that connect critical systems.
* Own architectural decisions around reliability, scalability and cloud infrastructure.
* Work hands-on with Python, Snowflake, Kubernetes, Docker, and Dash.
* Partner closely with quantitative analysts and business teams to deliver real-world solutions.
What We’re Looking For
* Proven experience in Python engineering (backend, APIs, infrastructure, or automation).
* A hands-on builder who thrives in high-performance, small-team environments.
* Curiosity and technical breadth across DevOps, cloud, and data architecture.
* Strong communicator – comfortable translating technical work for non-technical stakeholders.
* Degree in Computer Science, Engineering, or a similar technical field.
* Experience in finance is not essential – drive, adaptability and excellence are.
Why Join
* Work alongside exceptional engineers and analysts in a genuinely high-performing environment.
* Build systems that matter — no bureaucracy, no silos.
* Competitive base + significant discretionary bonus.
* Central London office, collaborative and fast-paced culture.
