Self-directed experiments and side projects count as evidenceYou can spot what LLMs miss: a wrong abstraction, a brittle data model, a spec that looks fine until it hits productionFluent English (written and spoken)Nice to have:Experience building AI/LLM product features (prompting, evaluation, guardrails)Worked in a B2B SaaS or HR tech environmentActivitiesYou get a business problem and you own it from there: solution concept, PRD, implementation, release, and measuring whether it worked. 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.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.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.What you’ll doFirst 30 days:Get deep into the Sharpist product: the AI Coach, the coaching platform, the learner journeyAudit existing solution concepts and PRDs; understand what's shipping and whyShadow one full problem-to-delivery cycle with the engineering teamShip your first small improvements or bug fixesFirst quarter:Own your first problem end-to-end: define the problem space, design the solution, write the PRDUse LLMs as a core workflow tool: prompt for specs, evaluate for efficiency and soundness, iterateWork directly with engineers to ensure what gets built matches what was intendedTalk directly to users and stakeholders to ground each problem in real insight, not assumptionsGive structured feedback on PRDs from others: technical feasibility, scope, edge casesYear one:Own multiple features end-to-end: define, ship, measure, and know what worked and what didn'tContribute to the team's weekly give & take: share what you learned, pick up what others discoveredMake the developer experience meaningfully better: tooling, workflow, or process improvements the team actually usesThe StackTypeScript, React, React Native, Node.js, MongoDB, Redis, Docker, Google Cloud, BigQuery, Google Dataform, Lightdash, Prometheus, Grafana.TeamYou will join an engineering team that values a 'builder' culture, focusing on shipping, learning, and outcomes.
