Principal Product Engineer

Mission

Finch was started by 2 friends (Nino & Steph 🙇🏾‍♂️🙇🏻‍♀️) who struggled with anxiety and depression and found self-care challenging to stick with. We decided to build Finch hoping to make self-care fun and accessible after seeing many others share similar struggles. Finch was launched in 2021, and our team is grateful to have helped over 20 million people on their mental health journeys.

Finch is profitable and we believe in responsible growth. We are a small but mighty team who are passionate about mental health.

Role Summary

At Finch, we’re reimagining how wellness meets gaming — making self-care not just easy, but irresistibly fun. As our Principal Product Engineer, you’ll blend creativity, product intuition, and technical skill to identify and execute high-impact opportunities that fuel our growth. You won’t just ship features — you’ll run bold experiments, uncover new growth loops, and engineer delightful experiences that stick. If you thrive at the intersection of data, design, and rapid iteration, we’d love to meet you.

We’re a small but mighty team, and as our 6th engineer, you’ll have an outsized influence on product direction, growth strategy, and engineering culture. This is a high-autonomy, high-impact role for someone who can both dream big and execute fast.

• Own the end-to-end lifecycle of product initiatives — from ideation and technical architecture to launch, analysis, and iteration.

• Build and optimize engagement and retention loops that drive sustainable user growth.

• Rapidly prototype and A/B test new ideas to validate assumptions and scale the winners.

• Collaborate with designers, animators, and founders to craft experiences that delight and convert.

• Shape engineering best practices, tooling, and culture for speed without sacrificing quality.

• Partner with product and data teams to uncover insights, prioritize opportunities, and measure impact.
  

• Invent new interaction patterns that make mental health support as addictive as social media—without the downsides.

• Engineer viral social features that drive organic growth and deepen community bonds.

• Transform wellness exercises like CBT into gamified, sticky daily rituals.

• Experiment with onboarding flows that double activation rates without adding friction.

• Build infrastructure to personalize experiences at scale, from beginners to power users.

• 5+ years of experience shipping consumer products (mobile or full-stack).

• Building products or features from 0-1

• Comfort with rapid iteration — you derisk ideas fast, ship often, and measure everything.

• Proven track record running A/B tests and making data-informed tradeoffs.

• Ability to simplify ambiguous problems into elegant, impactful solutions.

• Strong knowledge of mobile engineering best practices; bonus if you’ve scaled a product to millions of consumers.

• Availability for at least 6 hours overlap with 8am–6pm PST.
  

Nice to have: Flutter experience, wellness or gaming industry background, familiarity with behavioral design or habit formation frameworks.

• Competitive salary and benefits.

• High-impact work at a mission-driven company.

• A small, fast-moving team where your ideas directly shape the product.

• An inclusive, creative environment that values both innovation and execution.
