Senior / Staff Software Engineer

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.

If that mindset energizes you, read on.

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.

• 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.

• 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.

• A mission-obsessed crew shipping with speed and sky-high standards.

• Competitive salary + meaningful equity

• On-site culture in San Francisco with bi-annual off-sites for deep strategy & team bonding

• Time-off-as-needed vacation & generous parental leave

• Monthly wellness stipend (mental + 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.
