Building and growing products for curious, ambitious people who want to learn and keep getting better. Wanna join the tribe?
Deepstash is a micro-learning platform with millions of users consuming bite-sized insights on everything from psychology to productivity. Paladin teaches history through interactive, narrative-driven experiences. Protocol focuses on longevity and personal optimization, helping people make better decisions for their long-term performance. Together, our products serve over 10 million users worldwide.
Behind them is an awesome 60-person team based in Bucharest, led by repeat founders who’ve already built and successfully exited a global product company, but somehow decided to do it all over again. Bigger, better, even more fun this time.
We're a fast-growing consumer scaleup with strong unit economics and a proven ability to build, launch, and scale multiple products in parallel - fast, deliberately, and without unnecessary ceremony. Our current focus is on scaling what already works, expanding the product portfolio with the same core DNA, and strengthening the systems that let us move lightening-fast without breaking (too much) stuff.
This tends to be a great place and time for people who are comfortable making decisions, owning the outcome, and don’t need a committee to get good work out the door.
How We Build Product
- Outcome-driven: Every feature starts with a metric and a hypothesis, not a spec
- Mobile-first, globally distributed: Our users span Western markets and beyond
- AI-native workflows: We use AI as a force multiplier across specs, design, copy, and analysis
- Small teams, big ownership: You own problems end-to-end, from opportunity identification to post-launch measurement
- Speed over perfection: We'd rather ship and learn than polish and wait
Here is how you would fit in:
The Role
This is not a traditional design role. We're looking for a Product Designer who operates across the full product stack - someone equally comfortable analyzing a conversion funnel, writing a product spec, designing an interface, and presenting a strategy to leadership.
You'll own outcomes, not just outputs. That means you're responsible for identifying what to build, defining how it should work, making it look great, and proving it moved the needle.
A typical week might include:
- Analyzing engagement or conversion data to identify the highest-leverage opportunity in your area
- Writing a concise product spec that frames the problem, hypothesis, success metric, and proposed solution
- Designing interfaces and flows in Figma, static or interactive, that bring the spec to life
- Working directly with engineers to ship, troubleshoot, and iterate
- Running experiments, interpreting results, and deciding what comes next
- Using AI tools to draft specs, generate design explorations, write copy, or speed up analysis
- Conducting user research, usability tests, or surveys when you need deeper signal beyond the data
- Contributing to and evolving our design system and information architecture as we scale
What We're Looking For
Must-haves:
- Proven experience designing consumer mobile products that real people use at scale
- Strong design taste and UI skills - your portfolio should speak for itself
- Comfort with data: you can navigate analytics dashboards, read experiment results, and make decisions grounded in numbers
- Ability to write clear, structured product specs and communicate your thinking in writing
- Technical fluency - you don't need to code, but you understand constraints, trade-offs, and how things get built
- AI fluency - you actively use AI tools in your workflow and see them as essential, not optional
- Ownership mentality - you don't wait for someone to define the problem or hand you a brief
- Resilience to direct feedback - our team is straight-shooting and we expect you to be too
Strong signals:
- You've worked in a startup or high-growth environment where you wore multiple hats
- You can context-switch between a metrics review and a design critique in the same morning
- You have experience with growth, monetization, or retention, not just feature design
- You're already a Deepstash user who has opinions about our product
What We Offer
- Full flexibility: Work when and where you're most productive. We care about outcomes, not hours or location.
- Competitive compensation: Market-level salary plus equity, so you share in the upside as we grow.
- Founder-level context: You'll have direct access to company strategy, financials, and decision-making, not a filtered-down version.
- Accelerated growth: The scope and pace here will stretch you faster than most environments. One year here covers what takes three elsewhere.
- Real impact: Our apps have millions of users. What you ship gets used.
