Founding Principal Engineer

Department: Engineering

Location: New York City

Compensation: $200K – $240K • Offers Equity

Employment Type: FullTime

Who we are

Today, 1 in 5 children in the U.S. has a diagnosable mental health disorder, yet about half who need care never receive it. Handspring is a virtual mental health clinic for children, young adults, and families, and weve set out to rebuild this system from the ground up. Were a team of diverse, mission-driven people dedicated to making quality mental healthcare accessible to every young person and their family.

About the role

Were hiring our first senior engineer onshore: a Founding Principal Engineer who will sit beside the CEO and lead engineering.

Until now, our engineering team has been offshore. We ship fast, but weve reached the point where we need a senior technical leader in the building to help accelerate our roadmap, make architectural calls as we scale, and lead the adoption of AI across the organization.

Handspring values doers who can lead. Youll write production code on our most important systems, and youll lead: setting engineering standards, reviewing and mentoring, directing the offshore team, and shaping how engineering operates as we scale past Series B.

We move fast, operate with deep empathy, and value clarity, experimentation, and humility. If you want to be the senior engineer who builds the foundation rather than inherits it, wed love to meet you.

Key responsibilities

• Set the technical direction. Own architecture across telehealth, EHR, therapist onboarding, patient dashboard, and AI usage.

• Help make the build/buy decisions. We do not build for the sake of building, and are thoughtful about what to outsource vs build.

• Write the code that matters. Stay hands-on as a top individual contributor on the hardest, highest-stakes problems.

• Lead the team. Direct and level up the offshore engineers, establish how we work (code review, testing, on-call, incident response), and bring rigor without bureaucracy.

• Own reliability and security. Be accountable for the uptime and correctness of clinical systems, and for engineering practices that hold up to HIPAA and payor scrutiny.

• Build the eng org. As we grow, hire onshore engineers, define how the team is structured, and set the culture and standards a larger team will inherit.

• Define the stack. Currently use TypeScript across the stack, Node and React, deployed on AWS. You will help define the stack as we scale. We adopt new tech for leverage, not novelty

• Partner closely. Work directly with the CEO and translate clinical, growth, and operations needs into technical plans the team can execute.

Who you are

• You are energized about solving logistically complex problems

• 8+ years building production software, including time at the staff/principal level. Youve been the most senior engineer in the room and owned systems end to end.

• Deep full-stack strength. Youre comfortable owning everything from schema to UI.

• Youve led while staying hands-on: set standards, mentored strong engineers, directed teams, and raised quality without stepping away from the code.

• Experience working with distributed or offshore teams, or strong instincts for how to make that work.

• Youve built in regulated, high-reliability, or data-sensitive environments (healthcare experience is a plus) and take security and correctness seriously.

• Youre comfortable with ambiguity and limited resources, biased to ship, and energized by being the one who figures it out.

• You want to build in person

Success in this role means

• Increase in engineering velocity

• Acceleration of AI adoption across the organization

• Architecture decisions are made deliberately and hold up as we scale

• We can hire and onboard onshore engineers into a team with real standards and culture

Position details

• Full-time

• 3 days/week in-person in NYC

• The salary range is $200K – 240K, plus meaningful early-stage equity

• You must be based in the United States and have U.S. work authorization
