Staff Software Engineer, Product (Florianópolis)

Senior Product Engineer at LawnStarter (Remote - Florianópolis, Brazil)

About

LawnStarter is the nation's leading on-demand marketplace for lawn care and outdoor services, with over $100M in annual bookings. We are expanding to become the one-stop shop for all home services across three brands on a single shared platform. Our engineering teams build in small, focused initiative teams, working alongside Product Managers and Designers. AI coding agents are a key part of our workflow, enabling a small, senior team to ship more, faster, and with higher quality. We hire engineers who are driven by ownership and energized by shipping to a real marketplace.

• Collaborate closely with Product Managers and Designers as a true product partner.
• Make most technical calls with architect review for significant architectural decisions and input from peers.
• Ensure implementation quality through prompts, guardrails, evaluations, tests, and review loops for agent-authored code.
• Own the initiative's outcome and the metric it was designed to move.
• Maintain a high bar for production correctness, security, performance, and observability.
