Beacon 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.
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.
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 directly with senior engineers, including our CTO and Staff Engineers, on code review, system design, and technical decision-making.
Pair with the operations team to understand the problem before writing the code. Engineering at Beacon is operator-facing, and you will learn how to ship software that someone actually uses.
Currently enrolled in a Software Engineering, Computer Science, Computer Engineering, or related undergrad or graduate program.
Comfortable writing production-quality code in at least one of TypeScript, Python, or Go. You do not need to know all three, but you should be able to pick up a new language quickly.
Comfortable working in someone else's codebase. You can read code as well as you write it.
Curious about data systems, APIs, and the practical mechanics of LLM-driven applications. Prior exposure is a plus but not required.
Strong written communicator. Beacon runs on writing, and interns are expected to write design docs, PR descriptions, and updates that hold up to senior review.
Operator instincts. You take the time to understand the problem before reaching for a solution.
Prior co-op or internship experience shipping production software.
Exposure to modern data tooling (dbt, Snowflake, Databricks, Postgres at scale).
Experience with LLM APIs (OpenAI, Anthropic) or agentic workflow frameworks.
Side projects or open-source contributions that demonstrate independent technical curiosity.
Direct mentorship from senior engineers and the Beacon CTO.
Real ownership. You will ship code that the operating team depends on, not throwaway prototypes.
Exposure to a unique operational problem: building software that scales across a portfolio of very different businesses.
Competitive co-op compensation.
Remote-friendly, with travel to Beacon HQ in Toronto for onboarding and key in-person sessions.

Humility: We acknowledge that the path to getting to the right answer involves being wrong along the way. We have strong beliefs which are weakly held. We actively seek new ideas and believe we can learn from anyone at any time.

AI does not make hiring decisions: Every application is reviewed by a member of our team, and all decisions throughout the process are made by humans. We use AI to support efficiency and consistency, not to replace human judgment. We are committed to a fair, thoughtful, and equitable experience for every candidate.
