Our requirements
- Solid Engineering Background with a deep understanding of distributed systems and microservices architecture.
- Proficiency in at least one programming language used for infrastructure automation, tooling, and backend services (Kotlin, Java, Python or Go).
- Hands-on, advanced experience managing containerized environments and orchestration tools, specifically Kubernetes and Docker, alongside networking and service mesh concepts.
- Hands-on experience with Chaos Engineering practices (e.g., fault injection, failure scenarios) and performance testing frameworks (practical knowledge of Gatling or similar tooling is a plus).
- Deep experience configuring monitoring and observability stacks (e.g., Prometheus, Grafana, ELK), paired with a proven ability to identify single points of failure in complex systems and act as an Incident Commander during major outages.
- Strong practical knowledge of building and maintaining CI/CD pipelines and managing infrastructure using IaC tools.
- A strong sense of ownership and a data-driven mindset, with a track record of mentoring less experienced engineers, setting code quality standards, and shaping team architecture decisions.
Your responsibilities
- Leading and coordinating team-level projects to improve system reliability across our massive distributed architecture.
- Driving the design and implementation of complex reliability solutions and internal platforms, heavily utilizing our core ecosystem.
- Designing and building an AI agent to revolutionize our incident response workflow, alongside acting as a senior Incident Commander during major outages and leading blameless post-mortems.
- Developing and scaling our self-service performance testing platform, empowering engineering teams to run large-scale, distributed load tests with real-time observability.
- Building an automated resiliency platform for continuous fault injection and driving high-stakes, quarterly full Data Center failover experiments.
- Owning the reliability of the team's systems, managing technical debt, and automating infrastructure.
- Mentoring less experienced engineers and setting the standard for team code quality.
- Influencing how the team communicates and makes decisions on difficult system architecture problems at the Allegro scale.

- You will become part of Allegro Tech - We speak at industry conferences, cooperate with tech communities, run our own blog (it's been over 10 years!), record podcasts, lead guilds, and we organize our own internal conference - the Allegro Tech Meeting. We create solutions we love (and can) to talk about!
