Staff Software Engineer

Join Twilio as a Staff Site Reliability Engineer in our Platform Engineering organization. In this hands-on engineering role, you will own the reliability posture of significant parts of our production estate, define and operate against SLIs and SLOs, and drive improvements in service reliability. You will work without day-to-day guidance, applying deep subject-matter knowledge and industry-leading practices to improve Twilio's products, processes, and services.

• Assurer la santé et la résilience de la production chez Twilio, en étant responsable de la disponibilité, de la latence, de la capacité, de l'efficacité et des performances des services.
• Définir, instrumenter et opérer en fonction des SLIs et SLOs, et utiliser les budgets d'erreur pour orienter les priorités d'ingénierie.
• Écrire et déployer du code qui améliore la fiabilité du service, orchestrer des changements complexes entre les systèmes, diriger la réponse lorsque la production est dégradée.

• Twilio values diverse experiences from all kinds of industries, and we encourage everyone who meets the required qualifications to apply. If your career is just starting or hasn't followed a traditional path, don't let that stop you from considering Twilio. We are always looking for people who will bring something new to the table!
• A track record of improving the engineers around you through code review, design feedback, and mentorship
• Depth in production operations: incident command, post-mortem analysis, capacity planning, and observability
• Experience driving changes that span multiple teams, and the communication skills to build alignment without formal authority
• Demonstrated accountability for production systems — you have carried a pager for services that mattered and owned the outcome when they failed
• A record of preventing recurrence — reducing incident classes and operational toil, not just closing tickets
• Experience defining and operating against SLIs and SLOs, and using error budgets to inform engineering priorities
• Strong software engineering fundamentals: you build and ship production code, not only configure tooling
• 8+ years of related engineering experience, with a substantial portion focused on reliability, infrastructure, or platform engineering
• Experience with large-scale distributed systems in a cloud environment
• Familiarity with infrastructure-as-code, container orchestration, and GitOps-style delivery
• Experience with multi-region architecture, failure-domain design, or regional expansion work
• Background in chaos engineering, game days, or other proactive resilience validation
