• Investigate complex production issues across distributed systems, APIs, networking, queues, databases and GPU-backed workloads, participating in our engineering on-call rotation
• Lead and contribute to incident reviews and RCAs, turning recurring failure modes into lasting engineering improvements
• Reduce operational toil through automation, automated remediation and improvements to deployment safety, recovery and system resilience
• Work closely with Engineering and DevOps teams on capacity planning, performance, scaling and architectural improvements as the platform grows

Requirements

• Have strong experience operating and troubleshooting production systems at scale in an SRE, Production Engineering, Platform Engineering or similar role
• Have a strong understanding of distributed systems and are comfortable debugging across applications, databases, queues, containers, networking and infrastructure
• Have experience designing and operating observability systems using metrics, logs and distributed tracing
• Understand SRE principles including SLIs, SLOs, error budgets, capacity planning, incident management and reducing operational toil
• Have experience with Kubernetes, containers, IaC and automated deployment practices, alongside the ability to write software and automation using languages such as Python, Go or PHP
• Take strong ownership of production problems and are comfortable participating in an engineering on-call rotation, taking issues from initial investigation through to long-term remediation

Bonus

• Experience operating high-throughput or low-latency APIs and distributed systems
• Experience with bare-metal infrastructure, GPU environments or AI and ML workloads
• Experience with RabbitMQ or other distributed messaging and queueing systems
• Experience operating MySQL, Redis, ClickHouse or similar production data systems
• Experience with global traffic management, load balancing, CDN platforms and hybrid infrastructure environments
• Experience building automated scaling, capacity management or self-healing systems

Benefits

We’re a remote-first collective, meeting in person twice a year to plan, brainstorm, celebrate wins, and enjoy some face-to-face time. We have core hours for cooperative working and calls, but outside of that your calendar is yours. Work the hours that let you perform at your peak while also building a healthy life.

Our release cycles are fast and intense, but they’re followed by real downtime. After big pushes we expect the team to unplug, recharge, and come back ready & stronger than ever for the next leap.

• Generous paid time off – vacation, sick days, public holidays
• Meaningful stock options – share in the upside you create
• Remote-first setup – work from home anywhere we can employ you
• Flexible hours – own your schedule outside core collaboration blocks
• Family leave – paid maternity, paternity, and caregiver time
• Company retreats – twice-yearly gatherings in inspiring locations
