No hand-off, no shipping blind. We're working toward a one-week cycle, but we're not there yet. We'd rather ship at ~70% and learn from real usage than polish in private.</span></p><p style=";"></p><p><span style="color: #121317">The hard part isn't the coding. It's the synthesis: going from a fuzzy problem to a technically sound, scoped solution fast enough to keep the cycle moving. That's where most engineers slow down. That's the gap this role fills.</span></p><p style=";"></p><p><span style="color: #121317">LLMs handle a growing share of the implementation. What they can't replace is the judgment to know when the architecture is wrong, when an abstraction won't hold, when a shortcut becomes next quarter's incident. Catching that before it's built, not after.</span></p><p style=";"></p><p style=";"></p><h3><span style="color: #121317">What you’ll do</span></h3><p><strong><span style="color: #121317">First 30 days:</span></strong></p><ul><li><p><span style="color: #121317">Get deep into the Sharpist product: the AI Coach, the coaching platform, the learner journey</span></p></li><li><p><span style="color: #121317">Audit existing solution concepts and PRDs; understand what's shipping and why</span></p></li><li><p><span style="color: #121317">Shadow one full problem-to-delivery cycle with the engineering team</span></p></li><li><p><span style="color: #121317">Ship your first small improvements or bug fixes</span></p></li></ul><p style=";"></p><p><strong><span style="color: #121317">First quarter:</span></strong></p><ul><li><p><span style="color: #121317">Own your first problem end-to-end: define the problem space, design the solution, write the PRD</span></p></li><li><p><span style="color: #121317">Use LLMs as a core workflow tool: prompt for specs, evaluate for efficiency and soundness, iterate</span></p></li><li><p><span style="color: #121317">Work directly with engineers to ensure what gets built matches what was intended</span></p></li><li><p><span style="color: #121317">Talk directly to users and stakeholders to ground each problem in real insight, not assumptions</span></p></li><li><p><span style="color: #121317">Give structured feedback on PRDs from others: technical feasibility, scope, edge cases</span></p></li></ul><p style=";"></p><p><strong><span style="color: #121317">Year one:</span></strong></p><ul><li><p><span style="color: #121317">Own multiple features end-to-end: define, ship, measure, and know what worked and what didn't</span></p></li><li><p><span style="color: #121317">Contribute to the team's weekly give &amp; take: share what you learned, pick up what others discovered</span></p></li><li><p><span style="color: #121317">Make the developer experience meaningfully better: tooling, workflow, or process improvements the team actually uses</span></p></li></ul><p style=";"></p><h3><span style="">The Stack</span></h3><p><span style="color: #121317">TypeScript, React, React Native, </span><a rel="noopener" target="_blank" href="http://Node.js"><span style="color: #121317">Node.js</span></a><span style="color: #121317">, MongoDB, Redis, Docker, Google Cloud, BigQuery, Google Dataform, Lightdash, Prometheus, Grafana.</span></p><p style=";"></p><h3><strong>Working Model</strong></h3><p><span style="color: #000000">Hybrid in Berlin, 3 days per week in the office.
