Join the mission

Make good UX accessible to everyone.

VertaaUX exists to give teams truthful, no-bullshit UX and accessibility signals they can ship on today. We're building the UX audit engine that teams trust—not because it's fast (though it is), but because it's rigorous, accurate, and actionable.

Why this matters

Most teams ship UX decisions blind. They lack UX expertise, can't afford consultants, and don't have time for dense reports. We're changing that. One URL. One click. One clear path forward.

What we value

•Truth over vanity: We prioritize accuracy, clarity, and actionability over inflated scores. If 10 clones appear, our moat is the culture and rigor behind the signal.
•Quality as a moat: Real moat = quality + culture. Tactics can be copied; rigor can't. We raise the bar over time—good enough isn't enough.
•Ship improvements, not fluff: We respect users and ship what matters. Every recommendation must be human-readable in under 20 seconds, jargon-free, with "why it matters" and a suggested fix.
•High trust, low ego: Small, talent-dense team. Direct feedback. Shared ownership. We're building something that deserves to exist.

Technical Co-Founder

Remote (EU-friendly) / HelsinkiCo-founding role

Posted: 2025-12-15

Help us build the UX audit engine that teams trust. You'll own the technical foundation that makes truthful, no-bullshit UX signals possible—architecting systems where quality and rigor are the moat, not features. This is a chance to shape a product that deserves to exist.

Responsibilities

• Own architecture and execution across product, platform, and infrastructure—from audit engine to APIs to the systems that keep quality high.
• Build and ship core features that teams actually use: the audit engine, dashboard, APIs, scheduling, exports, and integrations.
• Set engineering standards that matter: quality gates, security, accessibility, testing, observability. Keep velocity high without sacrificing rigor.
• Recruit and lead early engineering hires as we grow. Build a team that values truth over vanity.
• Partner with product and go-to-market to align roadmap with what customers need, not what's easy to build.
• Make pragmatic tradeoffs under startup constraints while maintaining the quality bar that makes us different.

Requirements

• Strong full-stack engineering background with a bias to shipping. You've built systems that work, not just systems that look good.
• Experience designing systems that are reliable, secure, and performant. You care about the details that compound into real quality.
• Comfort operating with ambiguity and taking ownership without hand-holding. You're a founder, not an employee.
• Good product judgment and clear communication. You can explain technical tradeoffs to non-technical stakeholders and make decisions that matter.
• Willingness to take on founder-level responsibility and risk. This is a co-founder role—equity is primary compensation, and you're building something from zero to one.

Nice to Have

• Experience with Next.js/React and TypeScript in production—this is our stack.
• Background in web performance, accessibility (WCAG), or developer tools. You understand the problems we're solving.
• Experience with SaaS billing, subscriptions, and growth experiments. You've shipped products that make money.
• Prior startup experience (founder/early engineer) from zero to one. You know what it takes.

What We Offer

• Meaningful founder-level equity—this is the primary compensation component. You're building something you own.
• High autonomy and ownership over product and engineering direction. No bureaucracy, no hand-holding.
• A small, talent-dense team and direct customer feedback loops. You'll see impact immediately.
• Transparent collaboration and shared decision-making. High trust, low ego.

Senior AI Engineer (Data-heavy)

Helsinki, Finland (hybrid-friendly)Full-time

Posted: 2025-12-06

Own the predictive UX audit engine that makes truthful signals possible. You'll build the systems that extract meaning from DOMs, model user attention, normalize scores, and deliver audits in under 1.5 seconds. This is where rigor meets scale.

Responsibilities

• Design and evolve the DOM extraction + UPR pipeline (Puppeteer/Playwright) that feeds semantic, keyboard, and IA analyzers. This is the foundation everything else builds on.
• Train and productionize predictive UX models: saliency/attention, cognitive load, conversion opportunity scoring. You're building the intelligence that makes our audits accurate, not just fast.
• Build scoring normalization that fuses heuristics (usability, clarity, IA, accessibility, conversion) into consistent 0–100 outputs. No vanity scores—truthful signals teams can ship on.
• Instrument the audit engine for reliability, latency (<1.5s target), and resilience across thousands of concurrent audits. Performance isn't optional.
• Ship data contracts and schemas consumed by the frontend dashboard and PDF exports. Your work directly shapes what users see.
• Collaborate with security/governance to sandbox scans and enforce safe fetching policies. We respect users' sites and their security.

Requirements

• 6+ years building ML/AI systems in production (Python and/or Node/TypeScript). You've shipped models that work, not just models that impress.
• Hands-on with headless browser automation (Puppeteer/Playwright) and DOM parsing at scale. You understand the web at a deep level.
• Experience with saliency/vision or NLP models applied to UI/UX signals; strong model evaluation discipline. You know how to measure what matters.
• Comfort with scalable data infra (Redis/Vercel KV, vector DBs) and async pipelines. You build systems that handle load.
• Performance mindset: profiling, caching, and latency reduction for real-time user flows. Speed is a feature, not an afterthought.

Nice to Have

• Accessibility domain knowledge (WCAG), keyboard simulation, and semantic structure analysis. You understand why this matters.
• Experience with conversion optimization or UX research data sets. You've worked with the problems we're solving.
• Familiarity with Next.js App Router and serverless constraints. You know our stack.

What We Offer

• Competitive salary with equity options—you're building something you own a piece of
• Flexible hybrid work (Helsinki office + remote)—work where you do your best work
• Professional development budget—we invest in your growth
• Health and wellness benefits—we care about you, not just your output
• Latest tech stack and tools—no legacy constraints
• Impact-driven culture with autonomy—high trust, low ego

General Interest – Future Designer Roles

Remote (EMEA-friendly)Open application

Posted: 2025-12-15

We're building a product people trust for UX and accessibility decisions. If you're a designer who loves clarity, systems, and measurable improvements—who believes good UX is invisible and great UX is boring in the best way—we'd love to hear from you. Even if we don't have an exact opening today.

Responsibilities

• Tell us what kind of design work you want to lead (product design, UX writing, design systems, data visualization, research). We'll find the right fit.
• Collaborate with engineering to deliver polished, accessible, and performant UI. You understand that design and code are one system.
• Create flows and interaction patterns that are simple, scalable, and easy to understand. Consistency beats creativity in product UX.
• Contribute to a consistent design system and help raise the quality bar. Quality lives in the small decisions.
• Use feedback and data to iterate: ship, learn, and refine. You're comfortable with ambiguity and turning fuzzy goals into clear flows.

Requirements

• A portfolio that shows strong thinking (problem framing, rationale, and outcomes). Show us how you think, not just what you made.
• Ability to design for accessibility and inclusive experiences. You understand why this matters.
• Strong communication and collaboration skills across product and engineering. You can explain your decisions.
• Comfort working in ambiguity and turning fuzzy goals into clear flows. You're a founder, not just a designer.

Nice to Have

• Experience designing dashboards, analytics, or data-heavy products. You've worked with complex information.
• Familiarity with design systems and component-driven workflows. You understand systems thinking.
• Experience with UX research methods and synthesis. You know how to learn from users.

What We Offer

• High ownership and autonomy—you'll own meaningful design problems
• A small, talent-dense team that ships quickly—no design-by-committee
• Flexible remote-friendly collaboration—work where you do your best work
• Meaningful product impact—you'll see how your work helps teams make better UX decisions
