Job Description
Senior Backend Engineer
Livestorm
• Design and build backend services in Go, APIs, SDKs, and event-driven systems that shape how Livestorm evolves. • Own architectural decisions: define service boundaries, data models, API contracts, and patterns the whole organisation builds on. • Work closely with Product Managers and Designers to understand requirements, explore solution options, and ensure technical implementations align with user needs and product vision. • Drive API and SDK ergonomics: you care that the platform is a pleasure for other engineers to build on, not just "correct." • Lead cross-team technical initiatives and align engineering and product stakeholders around shared goals. • Contribute to build-vs-buy decisions on infrastructure, choosing pragmatically over dogmatically. • Mentor and provide technical guidance to other engineers through design reviews, pair programming, and direct feedback. • Champion good practices in testing, observability, CI/CD, and backend reliability. • Document technical designs, processes, and system architecture. • Contribute to strategic planning and decision-making for Livestorm's technical direction. • Navigate ambiguity with confidence: define the "how" when requirements are still forming, make pragmatic bets, and iterate.
Job Requirements
- Deep backend engineering expertise with a track record of designing systems at scale.
- Go is our primary language, whether it's already yours or you're a strong backend engineer ready to make it your home, you have the depth to ramp up fast.

- Good communication skills, able to talk through technical trade-offs with both engineers and non-technical stakeholders.
- Nice to have: Experience in a remote-first, distributed engineering environment.
- Prior experience building developer platforms, SDKs, or composable API layers used by other teams.
- Experience with large-scale migration patterns (strangler fig, parallel-run) moving from a monolith to a new architecture without breaking the world.
