Jobs at 25madison

Build products from concept to production across multiple startups. Responsibilities include prototyping, full-stack development, data modeling, integrations, AI-enabled workflows, testing, deployment, production reliability, and customer-informed product decisions. The role requires extensive use of AI coding tools, strong engineering judgment, independent execution, and collaboration with founders, designers, customers, and the CTO.

The Controller will build and lead StealthCo’s accounting and finance infrastructure, overseeing financial reporting, monthly close, AP, AR, payroll, cash management, reconciliations, controls, forecasting, and financial systems. The role supports acquisition accounting, entity integration, compliance, audits, tax coordination, executive decision-making, and finance-team expansion. Reporting to the CEO, the Controller will partner with leadership, investors, board members, and branch accounting teams in a fast-growing, private equity-backed platform.

Lead and grow the engineering organization, drive architecture and roadmap with the CTO, recruit and develop engineers, ship production software, establish processes for speed and quality, and collaborate with clinical stakeholders to translate needs into product.

Work directly with the CEO to turn strategy into execution: own OKRs, lead post-acquisition integrations, build scalable processes, analyze platform performance, support diligence and financial modeling, manage change communications, and develop marketing collateral to scale N43.

The role involves owning the architecture and initial product development for a system that interprets user behavior and makes real-time decisions in commerce. Responsibilities include defining system architecture, hands-on building, leading engineering teams, and collaborating with the founder on product direction.
