* Collaborate with a cross-functional team to deliver new features end-to-end
* Help maintain high engineering standards through testing, documentation and code quality
* Play a key role in maturing the platform as the company grows
What We’re Looking For
* Strong experience in backend development (Golang ideal, other backend languages considered)
* Solid frontend experience with TypeScript & React
* Experience building production-grade REST APIs
* Good understanding of concurrency, clean architecture, and system design
* Familiarity with containerisation and cloud environments
* Comfortable working across backend, platform, and some frontend areas
* Able to explain architecture decisions and trade-offs clearly
* Pragmatic, hands-on engineer who enjoys working in smaller teams
Nice to Have
* Experience with Python or ML-adjacent environments
* Exposure to Kubernetes or infrastructure-as-code tooling (eg. Terraform)
* Messaging systems and distributed workloads
* Experience contributing to a cloud-agnostic or multi-cloud environment
Why Join
* Work on technically challenging problems at the intersection of engineering and AI
* High ownership, high impact role in a growing team
* Supportive environment with strong learning and development focus
* Competitive compensation and stock options
* Flexible hybrid working model
