We’re supporting a high‑growth technology company entering a significant expansion phase. Product adoption is increasing, customer demand is growing, and the engineering function is scaling to support long‑term platform evolution. As part of this growth, they’re hiring a Principal Software Engineer to play a key role in shaping and scaling a complex, distributed platform. This is a hands‑on technical leadership role for someone who thrives on solving deep engineering challenges and designing systems built for performance, reliability, and long‑term maintainability.
The Opportunity
You will work at the core of a production‑scale platform, helping to guide technical direction while remaining deeply involved in implementation. Key responsibilities include:
- Designing and scaling distributed backend systems
- Leading high‑impact technical initiatives across core services and data layers
- Improving performance, reliability, and extensibility of existing systems
- Driving engineering best practices and architectural standards
- Contributing to design discussions, RFCs, and code reviews
- Mentoring senior engineers and raising the technical bar across teams
- Identifying and addressing scalability risks before they become blockers
- Contributing to modern, AI‑enabled engineering workflows
This is not a purely strategic role — you will remain hands‑on in the codebase.
What We’re Looking For
- 8+ years of backend or platform engineering experience
- Strong expertise in Python within large‑scale production systems
- Experience designing and operating distributed systems
- Deep understanding of APIs, data modelling, and system scalability
- Experience working on platforms, developer tools, or infrastructure‑oriented systems
- A pragmatic approach to balancing technical excellence with delivery
- Strong communication skills and ability to influence technical direction
- Experience working effectively in a remote‑first environment
Nice to Have
- Experience with Rust or Go
- Exposure to graph databases or complex data systems
- Experience within infrastructure, automation, or developer tooling environments
- Contributions to open‑source projects
