We’re looking for a senior Full Stack Engineer to join our fast-moving Product-Led Growth (PLG) team. You’ll take full ownership of building user-facing products that help people and companies reduce emissions, from backend logic to polished UIs.

Responsibilities

• Be part of our PLG team, transforming electricity data into applications used by millions.
• Build and own features and systems, including:
  • Our Interactive Map for real-time electricity data exploration.
  • The Developer Hub covering the API, documentation, onboarding, and usage tools.
  • The Data Explorer for visually querying and building dashboards.
  • Downloadable Datasets for carbon accounting and analysis.
• Manage the infrastructure behind the self-serve journey:
  • Signup flow, onboarding, billing, and CRM integration.
  • Product usage tracking, success automation, and enrichment tooling.
• Collaborate with designers and product leads to shape and build solutions.
• Ship quickly, iterate based on real feedback, and own your work in production.
• Help refine our building, deployment, and scaling processes.

Work Environment

• We move fast, stay focused, and give builders real ownership.
• We run 5-week cycles inspired by Shape-Up, with a 1-week cooldown for reflection.
• Engineers help shape the work and define how to solve problems.
• We prioritize learning and protect your time from interruptions.

Qualifications

• Senior experience in building and shipping full stack products end-to-end.
• Proficient in React/TypeScript and capable on the backend (Python, SQL, or similar).
• Ability to scope solutions based on fixed appetites rather than endless estimates.
• Experience in fast-paced, high-impact cycles focused on delivering value.
• Strong decision-making skills with a focus on usability and performance.
• Collaborative mindset with a willingness to take ownership of projects.

Bonus Points

• Experience with Stripe or payment systems.
• Familiarity with product analytics and data tooling (e.g., PostHog, BigQuery).
• Background in climate/energy domains.

Benefits

• Competitive salary + stock options.
• 6 weeks vacation + full health insurance.
