Primis is partnered with a wealthtech startup building the first data orchestration platform for financial advisors. They sync client data across an advisor's entire tech stack, solving a painful, expensive problem that touches an $80T market. Backed by strong institutional investors, with real momentum and a fast-growing early team.
They're hiring a Senior Software Engineer to lead development of their early product, with heavy influence over architecture and the product roadmap.

* Help build and maintain a strong, enjoyable developer experience
* Ensure the product runs smoothly in production, using observability and monitoring tools to triage and resolve issues
* Help hire and mentor engineers as the team grows
What they are looking for
* 7+ years of engineering experience with a strong track record of shipping high-quality, high-complexity systems at scale
* Experience building high-quality, delightful user-facing web applications
* Experience working closely with a cross-functional product team
* Excited to primarily be an individual contributor with a high degree of ownership
* Comfortable operating in an early-stage, fast-paced environment with real ambiguity and agency
* Impact-driven, with a bias towards action and ownership
* Customer-centric approach and a fast working pace
* Experience building B2B software and/or fintech software
* Experience at seed or early-stage startups (for example, being a first-3 engineer at a company)
* Experience building and maintaining open source software
* Previously started a company or launched personal projects
* Experience with AI prompting, models, and tools, both in your own work and helping level up a team
