Software Engineer (Senior / Staff +)

Why Patch, why now Patch exists to put the planet back in balance by scaling unified climate action through software, market infrastructure, and culture‑driven execution. Every day our platform not only curates the world’s most trusted carbon‑removal and environmental datasets—it also moves 100s of millions of dollars to projects that cut, capture, or store CO₂ for good. Our culture is built on three non‑negotiables We build the future we want – we don’t wait for permission; we shape the market. We’re all in this together – direct, empathetic teamwork inside Patch and across the climate ecosystem. We amp it up – urgency and unreasonably high standards because the planet can’t wait. The mission for this role Join the small team designing and scaling the data‑and‑transaction backbone of Patch’s climate‑finance engine. You'll turn a messy, global market into one that's structured, accelerated for AI and primed for climate impact. What you’ll tackle Own the climate‑commerce core – architect systems that ingest price & inventory data and settle high‑value payouts across currencies and rails. Prototype & harden – know when to sprint with a quick POC and when to engineer for fault‑tolerant, audited scale. Lead with context – mentor peers, review designs, and raise the bar while staying hands‑on. Partner across the org – white‑board with Product, Climate Science, and GTM to turn market pain points into elegant product experiences. What makes you a great match Track record building customer‑facing, data‑and‑transaction‑heavy products (startup speed or small, high‑ownership teams). Fluency in at least one backend language (we lean on Ruby + TypeScript) plus cloud‑native data stacks (Postgres, Kafka/PubSub, Snowflake, dbt) and payment/settlement systems. Daily driver of AI tools (Cursor, Windsurf, Claude Code) and hunger to push the frontier of AI‑assisted engineering. Product sense: you enjoy stitching user journeys as much as optimizing a query plan. Bias toward impact, humility, and teaching—you lift the whole team by sharing context relentlessly. What you’ll get A mission‑obsessed crew shipping with speed and sky‑high standards Competitive salary and meaningful equity On‑site culture in San Francisco with annual offsites for deep strategy and team bonding Unlimited vacation and generous parental leave Monthly wellness stipend (mental and physical) If building the transactional rails and data engine to scale climate finance—while using AI as a force multiplier—sounds like your kind of challenge, we’d love to meet you. Let’s rebalance the planet together.
