Staff Software Engineer, Product (São Paulo)
LawnStarter is the nation's leading on-demand marketplace for lawn care and outdoor services, with over $100M in annual bookings, operating across three brands (LawnStarter, Lawn Love, Home Gnome) on a single shared platform. This is a remote role for candidates located in São Paulo. The engineer is the engineering anchor of an initiative, working in a tight team with a PM and a designer, alongside engineering peers on adjacent initiatives. You own the full lifecycle: shaping the problem, deciding the technical approach, directing AI agents to implement much of the code, shipping to production, and owning the outcome with your team. You're measured by impact, not by lines of code merged.
Responsibilities
- ▹As the engineering anchor of an initiative, own the full lifecycle: shape the problem, decide the technical approach, direct AI agents to implement much of the code, and ship to production
- ▹Own the technical approach: architecture, data model, integration choices, rollout plan, observability, and rollback strategy
- ▹Bring significant architectural decisions to architect review, document them, and revisit if the data says you were wrong
- ▹Ensure implementation quality: the prompts, guardrails, evals, tests, and review loop that let agents ship safe, correct, production-ready code
- ▹Be accountable for agent-authored code, held to the same standard as the rest of the team working in a shared codebase
- ▹Daily working contact with your PM (scope, tradeoffs) and designer (UX decisions, in-tool prototyping), regular collaboration with engineering peers, and weekly check-ins with your EM
- ▹Own the initiative outcome: with your PM, present results 2-4 weeks post-launch
- ▹Hold a high bar for what ships: production correctness, security, performance, observability
Requirements
- ▹Staff-level engineering experience and the ability to make the call independently
- ▹Ownership mindset and energy for shipping to a real marketplace
- ▹Ability to lead AI coding agents at a staff-level quality bar: prompts that encode conventions, evals that catch issues before merge, tests that exercise the edges, observability that catches regressions
- ▹A true product-partner mindset: sitting at the table with PM and design and bringing engineering judgment to product calls
- ▹Knowledge of production-ready code standards: correctness, security, performance, observability
