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.

What you'd do

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.
Honesty: We are truth seeking in our approach to business problems. Business is a repeat game and we believe that human relationships generate alpha. We understand that trust is earned over a lifetime and can be lost in an instant.
Hunger: We play to win.
We hold ourselves to high standards and will not be outworked.
We take pride in having a deep sense of responsibility to ourselves, each other, our partners, and our customers.
We believe to whom much is given much is expected.
Horizon: We seek to build a generational software company. This will take decades. We manage our expectations and those of our partners to take advantage of the 8th wonder of the world - compounding growth.

What they want

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.

What you get

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.
