We're talking about the real environmental impact here, not another app for ordering avocado toast. Your tasks What we do Tasks What you'll actually do * Build the backbone and frontend (~80% backend, some full-stack adventures) * Design and ship features that can ensure we can have a stable system and that we sleep better at night * Own deployments because "it worked on my machine" isn't a strategy * Keep our cloud infrastructure fast, reliable, and cost-effective * Be the guardian of code quality (constructive gatekeeping is an art form but we swear by it) * Solve real problems * Turn "the sensor network is acting weird" into "here's what happened and here's the fix" * Make architectural decisions that scale with us * Help shape our tech stack because we value pragmatic sustainable solutions over resume-driven development Your profile Requirements You're probably a good fit if you: * Write backend code that doesn't make future-you cry * Have strong opinions about API design (and can defend them over coffee) * Actually enjoy diving into cloud infrastructure (AWS/Azure/GCP) * Know when to ship fast and when to refactor * Believe documentation is a love letter to your colleagues and your future team * Have shipped features with React/Vue or similar (you'll touch frontend sometimes) Tech you'll work with React js ; Python Django ; Docker ; CI/CD pipelines ; REST APIs ; OAuth2 ; PostgreSQL ; Git workflows that don't cause existential dread ; Whatever else makes sense for the problem We offer Our values (not just wall decorations) * Excellence: We ship quality, not excuses * Empowerment: Own your domain, make decisions, learn from mistakes * Achievement: Measurable impact > busy work * Impact: Every release saves water and makes water management more efficient (no pressure though) Benefits What you get * Autonomy to work how you work best * A team that actually reads your release notes and loves to have fun while working * Tools and resources that don't make you want to use your personal laptop * People who care about why we're building, not just what The vibe Small team. Real problems. No bullshit. We pair-program, we debate (respectfully), we ship, we iterate.

Please include something you've built that you're proud of (even if it's a side project). Shayp is committed to building a diverse team.
