Full Job Description
ABOUT BEACON SOFTWARE Beacon https://beaconsoftware.com is acquiring and operating a portfolio of vertical SaaS companies. Most private equity firms scale by adding people. We are building Beacon to scale by adding software. The thesis is simple: portfolio operations, value creation, and deal sourcing are bottlenecked by human attention, and an agentic operating system can lift that ceiling by an order of magnitude. We are building that system. It has two pieces. A sensing layer is a cross-portfolio data lake on open table formats with a feature store on top that makes the data agent-readable. An action layer runs workflows across three domains: how we run the portfolio, how we grow the portfolio, and how we acquire into it. Underneath both sits a feedback loop that captures every action and outcome with stable identifiers. ABOUT THE ROLE We are hiring a Software Engineering Intern to join the Beacon HQ engineering team for the Fall 2026 co-op term. You will work directly with our senior engineers on the platforms that power how we operate the portfolio: data ingestion across 25+ portcos, internal tools used by our operating team every day, and AI-powered workflows that we are embedding into both Beacon HQ and the portfolio products themselves. This is not a fetch-coffee internship. We are a small team and interns ship real code into production. Past interns have owned services end-to-end, written features that the entire operating team now depends on, and built tooling that meaningfully changed how a specific portco runs. The bar is high. The autonomy is real. WHAT YOU'LL DO - Ship production code into Beacon's internal platform. You will own a meaningful piece of work end-to-end, from design through deployment. - Build integrations between portco source systems (QuickBooks, HubSpot, Salesforce, Stripe, Postgres, and similar) and our central data platform. - Prototype and ship LLM-powered internal tools that our operating team uses to manage the portfolio. - Work
