Full Stack Engineer ($250k-$300k + Equity) at Caplight

About the role

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.

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.

Requirements

• 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.
