partsbase - Forward Deployed Engineer

Remote - USA2w ago

Requirements

• · Bachelor’s degree in Computer Science, Engineering, or equivalent experience. • · 10+ years building and shipping production software across backend, frontend, and integration work. • · At least 5 of those years operating systems you built yourself, on call for them, living with design decisions you made years earlier. • · Direct experience in a billable consulting, professional services, or solutions engineering capacity: scoping, estimating build effort and running cost, and owning a customer relationship. • · This role builds and certifies. A candidate strong in only one of the two is not a fit. • · Demonstrated production use of Claude Code, including CLAUDE.md http://CLAUDE.md, subagents, skills, hooks, MCP servers, and the Claude API. We ask for evidence, not years. • · Command of context engineering, tool use, model selection, and the failure modes of non-deterministic systems. • · Proven ability to catch AI output that is confidently wrong, and the automated checks you built so it does not reach a customer. • · Deep experience verifying data integrations: reconciliation strategy, parity at scale, sampling versus full comparison, and records that legitimately differ. • · Agent-driven testing and evaluation of non-deterministic behavior, including designing verification with Claude rather than hand-writing every case, eval design and scoring, and regression detection across prompt and model changes. • · Test automation at scale (Playwright, Cypress, or equivalent; API and contract testing), including flake elimination. • · A defect that escaped to a customer on your watch, that you owned, and that led you to change something systemic rather than add a test case. • · Instinct for when to stop solving a problem one customer at a time and productize it, and for when a pattern is not yet real enough to generalize. • · Experience evolving a partner-facing API, including the versioning and deprecation consequences of getting it wrong. • · C# and .NET including .NET Framework 4.6-era code, plus Python, TypeScript, and React with Next.js or React Native. • · AWS: deploying, operating, and debugging production workloads. • · REST integration at scale, and data integration across the maturity spectrum, from spreadsheet and flat file to batch, webhook, event-driven, and direct API. • · SQL Server, PostgreSQL, DynamoDB, and Elasticsearch. • · CI/CD with test automation in the pipeline, production observability (New Relic or equivalent), and automation platforms such as n8n. • · Credible in front of a customer: able to run a discovery session and leave them more confident than when you arrived, including when their entire process turns out to be a spreadsheet. • · Experience being overruled, or talking an organization out of something it wanted, and handling the aftermath professionally. • · Fluent in English language. • · Nice to have: aviation, aerospace, or defense exposure including ITAR/EAR awareness, and ERP integration (SAP, Oracle, Dynamics, or aerospace-specific systems). • · Nice to have: security testing practice, including OWASP Top 10 and the OWASP Top 10 for LLMs.

Responsibilities

• · Run technical discovery with customers and turn what you find into a technical scope, a risk assessment, and an estimate that covers both build effort and what the solution costs to run at their volume. • · Partner with Sales on scoping, and own the solution design. • · Build integrations end to end with Claude Code: agents and MCP servers, ERP and third-party connectors, file and batch ingestion, webhooks, and data mapping. • · Certify your own work, with parity against the customer’s source of truth, automated regression, and evidence the customer can sign off on. • · Build reusable verification tooling: parity harnesses, reconciliation, agent-driven test generation, and reporting a customer will accept. • · Define how we test agentic components, including prompt injection paths, tool and MCP permission scoping, and what an agent can do without a human in the loop. • · Design guardrails for agentic components in customer environments: scoped credentials, approval gates, output validation, audit logging, and rollback. • · Act as the primary technical interface for the engagement, and get through customer security review and change control without working around it. • · Hand off cleanly with documentation, runbooks, and monitoring. • · Convert what recurs across engagements into product: API capability, reference implementations, connectors, and an official Partsbase MCP server. • · Own developer experience for the integration surface, including documentation written for agents as well as humans, worked examples, and a self-service path. • · Between engagements, contribute across the full stack to the core platform. • · Build and maintain internal agentic tooling, including CLAUDE.md http://CLAUDE.md, subagents, skills, hooks, MCP servers, and n8n automations.
