WHY THIS ROLE Concourse is building the operating system for State and Local governments. Our platform is a configurable approach to tackling fragmented government data and workflows and turning them into smooth operations for public servants and the constituents they serve. As a Concourse Platform Engineer, you're not building a marginal feature for one product. You're contributing to the infrastructure that scales to our hundreds of products serving millions of Americans. You own the foundational layer: the data ingestion pipelines, AI workflow orchestration engine, and configurable primitives that support everything above them. Your role is to empower our Forward-Deployed PMs who sit alongside city and county teams, understand their specific workflows, and assemble each agency's solution. A bail management system for a county courthouse. IT Helpdesk for a school district. A water utility operations dashboard. An ERP for a mid-sized city. The FDPMs build those. Your job is to make sure they can. You're working on the deep infrastructure questions that make every deployment possible: how to reliably ingest data from a 30-year-old mainframe, how to run multi-step AI workflows that government users can audit and trust, how to expose primitives flexible enough to model any government process but constrained enough that non-engineers can build on them. These are hard, novel problems. The people solving them will define the next generation of government software serving us. WHAT YOU'LL DO - Design and own the connectors, ingestion pipelines, and data modeling primitives that normalize government data from legacy systems (mainframes, Oracle, flat files, proprietary APIs) into a consistent, queryable foundation - Build the infrastructure for long-running, multi-step AI workflows: task queuing, state management, retries, human-in-the-loop checkpoints, and the audit trails government compliance requires - Build and maintain the core primitives FDPMs build on top of: the workflow engine, role-based access model, form and action framework, and event system that let a non-engineer assemble a bail system or permitting platform without writing the plumbing from scratch - Bake in data isolation, access controls, and auditability as core platform features from the start, with a path toward compliance certifications (FedRAMP, CJIS, HIPAA) as we grow - Work directly with the founder on architecture decisions that will compound across every deployment we ever ship WHAT WE'RE LOOKING FOR - A portfolio: what have you built end-to-end, from scratch, under pressure? - Strong backend fluency in Python and/or Node, with solid instincts for data modeling, API design, and building systems that stay reliable and extensible over time - Enough frontend ability to build and reason about a UI, even if you won't own it - Hands-on experience using AI coding tools (Claude Code, Codex, Gemini CLI, Factory, etc.) as a core part of your daily workflow - Good instincts for abstraction: knowing when to generalize something into a platform primitive vs. when to just ship it - US citizen (required for government work) - Willing to work in-person in Flatiron, NYC (5 days/week) NICE TO HAVE: - Experience building developer platforms or internal tooling, devops/infrastructure, agentic AI orchestration, or work in regulated industries like healthcare, finance, or legal. ABOUT CONCOURSE Concourse is an early-stage startup with significant, accelerating revenue building AI-native software for state and local governments. This is the CEO's second venture after a successful exit. The government software market is enormous ($100B+), almost entirely unmodernized, and structurally underserved. Existing vendors built for Fortune 500 companies. Palantir built for defense agencies with unlimited budgets. Nobody has built the right platform for the thousands of state and local agencies running essential public services on systems older than the internet. Our team members, bolstered by the latest in agentic engineering and modern software design, are fixing that. Our team is based in Flatiron, NYC.
