[Remote] Staff Platform Engineer

Note: The job is a remote job and is open to candidates in USA. Charlie Health is a rapidly growing organization focused on connecting individuals to life-saving behavioral health treatment. As a Staff Platform Engineer, you will own critical platform primitives, ensuring the reliability and safety of code while collaborating with engineering teams to enhance their capabilities.

Responsibilities

• Own one or more platform primitives end to end, from architecture and build through production operation and long-term evolution
• Build the deterministic quality gates that let agent-written code ship safely: automated end-to-end testing, golden test datasets, spec templates, and schema change safety
• Deliver core services on the team's own paved roads, finding the potholes before any product squad does
• Write specs that name invariants, error cases, security implications, and acceptance criteria, and orchestrate agent swarms on hard multi-system work
• Coach Senior engineers and product squad engineers on spec writing, agent orchestration, and platform patterns
• Define the reliability conventions for your area: SLO definitions, observability standards, and incident response practice, including a seat in the on-call rotation
• Steward the security and compliance posture of your primitive, and stay aware of what it costs to run
• Partner with product squads as they federate into the supergraph and adopt the event substrate during the migration onto the new platform
• Design cross-service patterns that product squads adopt, and treat adoption as the measure of success rather than delivery alone
• Document the standards in your domain as architecture decision records and bring them through our Architecture Advice Guild

Skills

• 7+ years of software engineering experience, including several years designing and operating distributed systems or platform components that other teams build on
• Depth in at least one of these areas, enough to own it end to end: GraphQL federation, real-time stream processing (Flink, Spark, KsqlDB, or similar), graph databases (Memgraph, Neo4j, Amazon Neptune, Dgraph, or similar), or authorization systems with ReBAC and RBAC models (Zanzibar, OpenFGA, Cedar, or similar)
• Experience with skills, MCPs, harnesses, agentic tooling ecosystems, or agent orchestration for software development
• You build with AI agents as part of your daily work. You write specs agents can implement, run agents for real delivery, and know where agent output needs human judgment
• Experience with data modeling for systems of record, including safe schema changes against live production data
• Proficiency in the stack we run: TypeScript and/or Python services, Postgres, and AWS managed primitives
• A track record of driving workstreams that span multiple engineers and quarters without people authority
• Comfort operating production critical-path systems, including on-call, in a regulated environment
• Clear, direct communication with engineers, product partners, and leadership
• This is a remote role. Our teams work across time zones and are available during core meeting hours (12PM to 5PM EST)
• Event streaming systems such as Kafka, including schema governance and production operation
• Healthcare data standards (FHIR, HL7v2) and engineering in a HIPAA-regulated environment
• A strangler-fig migration or large platform cutover you contributed to
• Time on a platform or developer experience team
• Fluency with domain-driven design or event storming
