Job Summary

About us - Join our mission to fight climate change

Were building the carbon accounting platform that enterprises use for compliance reporting and decarbonization strategy. Our platform processes millions of data points to calculate auditable CO2 emissions and we need technical leaders who can own entire product domains.

We are looking for a Lead Engineer to take end-to-end ownership of a core product domain in our carbon accounting platform. Youll be the technical authority for their area: making architecture calls shipping features in tight cycles and being the one who keeps their domain reliable.

This is a hands-on role - you write code daily lead by shipping and own your systems from design to production.

If you want to own a core part of a climate tech platform and see your work directly impact how companies measure and reduce emissions keep reading.

We are open to hiring fully remotely for this role.

What youll do:

Own a product domain end-to-end - architecture decisions feature delivery reliability and operational health for your area of the platform.
Ship features in 2-3 day cycles - break down projects into small deliverables write tech docs and drive them to production.
Design and build data validation and processing capabilities - ensuring customers can trust the numbers they see
Lead technical discovery for your projects - implementation approach testing strategy rollout plan risks - reviewed by peers before development starts
Own what you build through production - deployment monitoring and incident response.

Youll thrive in this role if you:

Bring 8 years of experience in software engineering with 2 years owning a product domain end-to-end.
Have experience with data-intensive backend systems in B2B SaaS.
Are a strong backend engineer fluent in TypeScript/ - experienced with NestJS or similar frameworks solid with PostgreSQL comfortable navigating a React frontend when needed.
Have owned a product domain before - not just implemented features but made the architectural calls and been the person who knew how the whole thing worked.
Care deeply about data correctness - youve built systems where wrong output is worse than no output and you think naturally about validation and edge cases.
Ship small and often - youre uncomfortable when PRs sit for days and you treat in production as the only definition of done.
Have a DevOps mindset - you own your components from technical design to release monitoring and maintainability.
Debug across layers - when somethings wrong you trace it end-to-end rather than pointing at someone elses service.
Write clear technical documents that other engineers actually use.
Familiarity with AWS (ECS Lambda SQS Aurora).

Nice to have

Experience with data ingestion pipelines ETL systems or analytics tooling ( Snowflake).
Experience stabilizing or rewriting legacy systems incrementally.
Climate tech sustainability or compliance-grade data systems.
Series A/B startup experience.
