Platform Engineer

About the role

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
