Responsibilities
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
Qualification
Required
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
Benefits
Competitive salary and meaningful equity
On-site culture in San Francisco with bi-annual off-sites for deep strategy and team bonding
Time-off-as-needed vacation and generous parental leave
