Our customer base has grown fast, and our platform has to grow with it. We're looking for a senior backend engineer who takes a service from idea to production on their own: designs it, builds it, ships it, and runs it. You'll work on scale, performance and reliability, and you're not afraid to open old code and make it better.
About IONIXIONIX External Exposure Management protects enterprises' external attack surface from cyber risks and increases security team efficiency by providing tools that shorten the time to discover and prioritize exposures. IONIX discovers every internet-facing asset, assesses dependencies and connections, and validates exploitable risks so teams can remediate the exposures that matter. Global leaders including BlackRock, Infosys, Sompo, The Telegraph and E.ON depend on IONIX to manage their complex and dynamic attack surface.
Responsibilities- Own features and services end-to-end: design, development, deployment and production.
- Solve scale and performance challenges in a platform serving a fast-growing customer base.
- Improve and modernize existing code, not only write new code.

- Lead technical initiatives and raise the bar for the team.
- Take part in a shared on-call rotation.
- 5+ years of hands-on backend development on large-scale, production-grade systems.
- Strong Python and/or Go - a must.
- Excellent coding skills and a solid grasp of large-scale architecture and design patterns.
- Proven end-to-end ownership: you've led features or services from design to production.
- Daily, hands-on use of AI coding tools and agents.
- B.Sc. in Computer Science, Computer Engineering, or equivalent experience.
Nice to have
- Experience scaling PostgreSQL.
- Cloud environments, containers and Kubernetes.
