The Role
You 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 do
First 30 days:
- Get deep into the Sharpist product: the AI Coach, the coaching platform, the learner journey
- Audit existing solution concepts and PRDs; understand what's shipping and why
- Shadow one full problem-to-delivery cycle with the engineering team
- Ship your first small improvements or bug fixes
First quarter:
- Own your first problem end-to-end: define the problem space, design the solution, write the PRD
- Use LLMs as a core workflow tool: prompt for specs, evaluate for efficiency and soundness, iterate
- Work directly with engineers to ensure what gets built matches what was intended
- Talk directly to users and stakeholders to ground each problem in real insight, not assumptions
- Give structured feedback on PRDs from others: technical feasibility, scope, edge cases
Year one:
- Own multiple features end-to-end: define, ship, measure, and know what worked and what didn't
- Contribute to the team's weekly give & take: share what you learned, pick up what others discovered
- Make the developer experience meaningfully better: tooling, workflow, or process improvements the team actually uses

Working Model
Hybrid in Berlin, 3 days per week in the office. We find that being together in person is what builds the kind of relationships where real conversations happen: the ones that change how you think, how you work, and how the product evolves.
Who You Are
Must-haves:
- You think like a Product Engineer: you've had full ownership of feature development, defining the solution, not just building what someone else specified
- You can write a clear, technically grounded PRD, and you know what makes one bad
- You have a strong intuition for UX: what confuses users, what creates friction, what feels right
- You use AI/LLM tools as a core part of how you work, across specs, prototyping, and implementation, not as a gimmick. Self-directed experiments and side projects count as evidence
- You can spot what LLMs miss: a wrong abstraction, a brittle data model, a spec that looks fine until it hits production
- Fluent English (written and spoken)
Nice to have:
- Experience building AI/LLM product features (prompting, evaluation, guardrails)
- Worked in a B2B SaaS or HR tech environment
What We Value
- Ownership: When ownership is unclear, you step forward. When you're blocked, you find a solution; you don't shift the problem up
- Clarity: You write specs that don't need a meeting to explain
- Judgment: You know when something is technically sound vs. technically plausible-but-painful
- Speed: You move fast without creating rework for others
- Mission belief: You genuinely care about helping people. That's why you're here
What We Offer
- Unlimited Coaching: Access certified coaches to support your personal and professional growth whenever you need it.
- Hybrid working model: Enjoy the flexibility to work both remotely and on-site.
- Growth Budget: 1000 EUR per year dedicated budget for courses, workshops, and certifications.
- Pension Scheme (bAV): Attractive retirement savings program.
- Quarterly Magnetic Week: Connect with your colleagues at exciting events that inspire and excite.
- The "Builder" Environment: A culture that values shipping, learning, and outcome over output.
