Placer.ai is a location analytics platform that provides visibility into locations, markets, and consumer behavior for Fortune 500 companies, governments, and nonprofits. The company reached $100M ARR in 6 years, achieved unicorn status ($1B+ valuation) in 2022, and is one of North America's fastest-growing tech companies.
You will be the first engineer on Placer's new B2C team, working directly with the Vice President of Consumer Apps. This is a founding engineer role building consumer-facing mobile applications that allow users to contribute data to the Placer platform. You will own the technical product end-to-end: native mobile apps (iOS and Android), backend services, permission and consent flows, and integration with Placer's core data pipeline.
The team operates lean and fast, leveraging AI development tools to ship quickly. You will architect and build Placer's first consumer apps on a scalable foundation, own the quality of the consumer experience from onboarding through engagement, and build permission and consent flows compliant with App Store and Google Play policies in partnership with Legal and Privacy.
Key responsibilities include: architecting and shipping native mobile apps and backend services; owning the full consumer experience and UX quality; building permission and consent flows; instrumenting the complete funnel (attribution, install, registration, permission grant, engagement, retention); setting up analytics and A/B testing; shipping on a move-fast-fail-fast cadence with releases in days; using AI-first development practices; embedding Placer's data collection technology; building fraud and abuse controls; making technical decisions on stack and architecture; owning production reliability and monitoring; and helping hire and mentor future engineers.
REQUIREMENTS:
- Bachelor's degree in Computer Science or related field, or equivalent practical experience
- 6+ years of software engineering experience, including at least 4 years on B2C products (consumer-facing mobile apps shipped to general public)
- Genuine passion for UX with shipped consumer experiences you can walk through screen-by-screen and explain design choices
- Comfortable in move-fast-fail-fast environments: shipping imperfect first versions, reading data, and discarding work that doesn't perform
- Mastery of AI development tools (coding agents, AI-assisted design, testing, code review) with concrete examples of multiplying output on small teams
- Track record taking at least one consumer app from zero to launch as founding or early engineer, and scaling it post-launch
- Deep expertise in one native platform (Android/Kotlin or iOS/Swift) and working fluency on the other, or equivalent cross-platform experience with native modules
- Experience integrating SDKs into consumer mobile apps
- Backend experience building APIs and data services on cloud platforms (Python and GCP preferred)
- Direct experience with App Store and Google Play review, including data-safety declarations and handling policy rejections
- Clear written and verbal communication with judgment to raise risks early
NICE TO HAVES:
- Demonstrated use of AI tools for efficiency (professionally or personally)
- Comfort integrating generative AI into daily workflows
