Senior SRE, Platform Software Engineer

Responsibilities

• Take an architect-approved design and turn it into production code that ships through Git Ops + the CICD release pipeline.
• Build and operate one or more bounded contexts of the Neo Cloud SRE platform.
• Own 1-2 of various services including collection, alert, correlation, and SLO frameworks.
• Implement fault-prediction and remediation workflows.
• Manage hardware lifecycle and data center operations.
• Develop services for identity, secrets, tenant configuration, and customer bridging.

• 7+ years of production software engineering experience, including 2 or more years operating what you built (real on‑call experience, not just shipping code).
• Production‑depth mastery of at least one systems‑grade language—Go (preferred), Rust, or Java.
• Proficiency in Python for tooling and SDK work.
• Strong grasp of at‑least‑once vs. exactly‑once trade‑offs, idempotency, back‑pressure, leader election, consistent hashing, gossip, and fan‑out.
• Experience at production scale with Prometheus, Victoria Metrics, Mimir, Thanos, Loki, Elasticsearch, Tempo, Jaeger, or Open Telemetry.
• Hands‑on experience with Argo, Flux, Helm, Kustomize, Cosign signing, signed‑bundle promotion, and blast‑radius‑aware rollouts.
• Proven experience writing a controller or CRD handling real production traffic, with a deep understanding of watch‑cache mechanics, leader election, and reconcile loops.
• Experience executing end‑to‑end mTLS bootstrap with certificate rotation.
• Hands‑on experience with Hashi Corp Vault or cloud KMS (AWS KMS / GCP KMS).
• Ability to read a Prometheus query plan, build a recording‑rule strategy, and write SQL that joins per‑tenant telemetry against analytics‑lake tables.
• Rigorous approach to unit, integration, contract, chaos, and soak testing.
• Ability to author clear design docs that align with existing platform architecture, create runbooks optimized for 3 AM on‑call responses, and write intent‑driven PR descriptions.
