serverfarm - Platform Architect

• 10+ years building back-end and platform systems, and in the last three years you have personally shipped a multi-tenant SaaS platform or control plane on Kubernetes, writing production code, as the technical decision-maker. • You have designed the domain data model for a complex operational system (assets, hierarchies, time series, events) and owned its evolution across releases, with the compatibility, versioning and migration decisions that came with it. • You have delivered retrieval performance at telemetry scale: chosen time-series and relational storage (PostgreSQL with TimescaleDB or equivalent, with a columnar engine such as ClickHouse for analytical and AI workloads), designed queries for live and analytical workloads over long histories, and met API latency targets. • You have built hands-on on a major public cloud (GCP, AWS or Azure) with Kubernetes and Helm, with judgment about when a managed service is the right call and when portability matters more. • You have built identity, tenancy and security by design into enterprise SaaS. • You have designed and published an API or data-model specification that other teams, and ideally external organisations, built against, and written architecture decisions that engineers worked from. • You have been a senior individual contributor on a platform's foundational production code. • Used agentic coding tools and directed and reviewed agent-written code at volume. • Knowledge of or experience with DCIM products: the data they manage and how data-center operators use them. • Designed platform ingress with Kafka-compatible streaming (Kafka, Redpanda or equivalent) and MQTT brokers (EMQX, HiveMQ or equivalent). • Instrumented a platform with OpenTelemetry for its own observability. • Integrated large language models into a platform: a model gateway, retrieval over operational data, tool interfaces an assistant can call. • Run a platform across public clouds, or shipped software both as a cloud service and in customer-hosted or air-gapped environments. • Serverfarm is committed to providing an equal opportunity workplace and offers paid time off, paid holidays, 401k and FULL coverage medical, dental and vision.
