Senior DevOps Engineer

📋 Description

• • Own the reliability, scalability, and security of Ada’s cloud-native infrastructure, serving millions of AI-powered customer conversations every month. You will architect and automate systems that keep our platform running 24/7 while enabling product teams to ship new features daily.
• • Design, build, and maintain Kubernetes clusters across multiple AWS regions, ensuring zero-downtime deployments, auto-scaling, and cost optimization. You will define Infrastructure-as-Code patterns using Terraform and Helm that the entire engineering organization can reuse with confidence.
• • Establish and continuously improve CI/CD pipelines that cut release cycles from hours to minutes. You will integrate security scanning, automated testing, and progressive rollout strategies so every commit reaches production safely and quickly.
• • Champion observability best practices by implementing Prometheus, Grafana, Loki, and distributed tracing. You will set SLOs, error budgets, and on-call rotations that balance velocity with rock-solid reliability, and you will lead blameless post-mortems that turn incidents into learning opportunities.
• • Partner closely with machine-learning engineers to optimize GPU workloads and model-serving infrastructure. You will fine-tune autoscaling policies, reduce cold-start latency, and keep inference costs predictable as demand spikes during product launches.
• • Automate operational toil away—think database migrations, certificate renewals, and secrets rotation—so the team can focus on high-impact work. You will script in Python or Go, build custom operators, and contribute reusable modules back to the open-source community.
• • Strengthen our security posture by embedding guardrails into every layer of the stack. You will manage IAM policies, network segmentation, container image scanning, and compliance evidence collection for SOC 2 and ISO 27001 audits.
• • Mentor junior engineers and create runbooks, architectural decision records (ADRs), and internal tech talks that level up the entire organization. You will foster a culture where operational excellence is everyone’s responsibility.
• • Collaborate with customer success and support teams to triage and resolve high-severity incidents, translating customer pain into systemic fixes. You will join a lightweight on-call rotation that respects work-life balance while keeping the platform resilient.
• • Experiment with emerging technologies—service mesh, eBPF, chaos engineering—and run proof-of-concepts that inform Ada’s long-term infrastructure roadmap. You will present findings in weekly engineering demos and quarterly planning sessions.
• • Drive cost-optimization initiatives that save six-figure cloud spend without sacrificing performance. You will analyze usage patterns, negotiate reserved capacity, and implement intelligent auto-scaling that aligns spend with business growth.
• • Contribute to Ada’s remote-first culture by participating in virtual coffee chats, cross-team guilds, and annual off-sites. You will help shape engineering rituals that keep us connected, inclusive, and inspired across time zones.
