## Job Description

## Responsibilities
- Build customer-facing workflows that streamline the research, sourcing, and purchasing of environmental commodities.
- Partner with Product and Design to converge on 80/20 solutions—prioritizing fast learning and high impact.
- Act as the DRI on initiatives: clarifying scope, sequencing work, aligning stakeholders, and driving projects to the finish line.
- Raise the quality bar through thoughtful reviews, pragmatic architecture, and a bias toward getting the right things live.
- Communicate clearly and in writing, using meetings primarily for active collaboration and decision-making.

## Requirements
- Product engineer's mindset: care about the user, ask “what problem are we actually solving?”, and turn messy requirements into crisp scope.
- High ownership and urgency: proactively propose what the next 3–12 months should look like and hold yourself to a high bar.
- Collaboration with accountability: communicate directly with respect, disagree and commit, and prefer a DRI model over consensus-by-default.
- AI-native workflow: routinely use AI to tighten feedback loops and unblock yourself, without lowering the bar for quality or judgment.
- Excellent engineering fundamentals: build reliable, secure, and maintainable software, making pragmatic trade-offs that protect long-term velocity.
