SRE/Site Reliability, AWS
About the role Sygnum’s Platform team builds and operates the cloud foundation that every product engineering team ship on: the AWS landing zone, our Kubernetes platform, and the shared services (API gateway, event streaming, secrets, observability, delivery) that turn raw cloud into a product-ready runway. We’re a small team with a large surface area, and we run a regulated fintech environment where every change is auditable.
We’re hiring a Senior Platform Engineer to help evolve that platform — pushing the developer experience forward while keeping reliability, security, and cost under control. You’ll split your time roughly between building (new platform capabilities, module work, self-service tooling) and running (upgrades, on-call, incident response, hardening).
What you’ll do- Design and ship improvements to our AWS multi-account landing zone and shared networking / IAM baselines, all through Terraform and a PR-driven plan/apply workflow — no click-ops in production.
- Operate and evolve our managed Kubernetes platform: cluster lifecycle, workload identity, autoscaling, node image hardening, and Git Ops-based delivery.
- Own or co‑own shared platform services: API gateway, event streaming, service mesh, certificates, secrets management, and the metrics/traces/SLO stack.
- Improve the paved road for product teams — templates, modules, guardrails, and self‑service — so the safe path is also the easy path.
- Participate in the platform on‑call rotation, lead incident response when needed, and drive blameless postmortems that actually change how the system behaves.
- Contribute to our reliability posture: SLO tiers, backup and DR readiness, and security baselines (encryption, TLS, least‑privilege IAM).
- Keep changes auditable and release‑disciplined — we operate in a regulated environment, and infrastructure changes must remain traceable.
- 5+ years in Platform / SRE / Dev Ops roles with production ownership of cloud infrastructure at meaningful scale.
- Deep AWS hands‑on experience: IAM, VPC and networking, and managed Kubernetes (EKS or equivalent).
- Terraform in production, with a PR/plan‑review workflow (Atlantis, Terragrunt, or similar).
- Solid Kubernetes operational chops: troubleshooting real workloads, autoscaling, Git Ops delivery.
- Comfortable on an on‑call rotation and leading incident response under pressure.
- Clear written communication — runbooks, postmortems, and design notes that other teams can actually use.
- Regulated‑industry experience (banking, fintech, healthcare) with audit and change‑control constraints.
- Familiarity with any of: API gateways (Kong or similar), event streaming (Kafka/MSK), service mesh (Istio/Envoy).
- Exposure to a secondary cloud (Azure/GCP) or multi‑cloud operations.
- Contributions to internal developer platforms, shared Terraform modules, or open‑source infrastructure tooling.
