Company Description

Caplight is building the real-time data and trading infrastructure for private markets, bringing transparency to historically opaque and illiquid assets. Based in San Francisco, Caplight provides institutional players with the pricing and tools needed to move quickly on private securities, transforming fragmented data into actionable financial intelligence.

Job Description

Join Caplight’s founding team as a Full Stack Engineer to build the infrastructure powering private market trading. You will own entire product areas, from real-time pricing data surfaces to institutional-grade trading interfaces. This high-impact role requires a blend of technical depth, product instinct, and a strong design sense to create sophisticated financial tools.

Location

San Francisco, USA

Why this role is remarkable

Join a high-leverage founding team in San Francisco with significant influence over the product’s direction and the company’s ultimate culture.

Tackle deep technical challenges in private market infrastructure, turning fragmented, stale data into real-time, institutional-grade trading and pricing tools.

Experience a unique "AGI-pilled" environment where you are encouraged to max out parallel agent management to accelerate development and product delivery.

What You Will Do

Own and build end-to-end product features, from the underlying data infrastructure to the sleek, intuitive interfaces relied on by institutional users.

Collaborate closely with the small founding team to translate complex business requirements into high-performance financial infrastructure and data surfaces.

Leverage advanced AI workflows and agent management to ship features rapidly without compromising on design quality or technical robustness.

The ideal candidate

At least 5 years of full-stack engineering experience with a proven track record of shipping complex, user-facing products at scale.

Strong product instincts and an exceptional eye for design, capable of building beautiful, functional features without needing a dedicated designer.

An entrepreneurial, "AGI-pilled" mindset with high business acumen and the ability to move fast on ambiguous, cross-disciplinary problems.

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

How does this work?

Jill is the AI recruiter working for the company. She recruits from Jack's network.

If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
