At Lago, we're on a mission to make Monetization simpler for tech companies.
As the leading open-source billing platform, we help businesses build flexible pricing models and scale with confidence. We've raised over $22 million in funding from top-tier investors including Y Combinator and FirstMark.
Our platform has garnered around 10K stars on GitHub, a testament to our active and growing developer community. Companies such as PayPal, CoreWeave, Synthesia, and Mistral.ai choose Lago for their billing. And we have barely spent any money on Marketing or Ads so far.
We're a team of ambitious, focused individuals who solve hard problems with excellence and accountability. At Lago, we value reliability and proactivity. We trust each other to own tasks, drive them to completion, and continuously improve them. While we encourage you to try fast and “fail fast”, we also expect you to learn fast: make mistakes, but don't make the same one twice.
If you're excited by challenges and want to grow alongside a high-performing, supportive team, this is the place for you.
What you'll do
Own product design end-to-end, from problem framing to shipped product.
Design complex B2B workflows across billing, pricing, metering, invoicing, subscriptions, wallets, and analytics.
Turn messy, technical, and ambiguous problems into clear, intuitive product experiences.
Prototype quickly to test ideas, clarify direction, and accelerate decision-making.
Partner closely with engineers during implementation to make sure design quality survives shipping.
Who you are
You ship fast and stay in motion: you'd rather get something in front of users this week than perfect it for a month.
You elevate craft while moving fast: pixels, copy, empty states, edge cases, and interaction details matter to you.
You're AI-native in how you work: you use AI tools to extend what you can design, prototype, write, research, and build.
You stay close to the market: you design for where product and AI capabilities are heading, not only what Lago can do today.
You communicate clearly: you align people, challenge assumptions constructively, and create clarity when things are ambiguous.
Requirements
5+ years of experience designing and shipping high-quality digital products, ideally in B2B SaaS, developer tools, fintech, infrastructure, or complex workflow products.
A strong portfolio showing end-to-end product thinking: problem framing, UX exploration, visual design, interaction details, and shipped outcomes.
Exceptional visual and interaction design skills across typography, layout, information hierarchy, states, microcopy, and accessibility.
Ability to prototype quickly in Figma, code, AI-assisted tools, or other environments to explore ideas and accelerate decisions.
Strong communication skills in English, both written and spoken, with the ability to align people, explain trade-offs, and defend a design direction clearly.
Work with top-tier international talent: Join a team that values excellence, slope over intercept, and accountability. We have convinced top-tier investors and companies to trust us with mission-critical systems like billing. We have 12+ nationalities on the team and are building a global company with a global culture.
Shape the future of monetization and fintech: The world is changing. Monetization systems are shifting with AI, and you will be at the forefront of this revolution.
Fully remote: Work from anywhere in Europe
Competitive package: Competitive salary and stock options
Make an impact: Your work will directly shape how customers like Mistral, Groq, Synthesia, and established enterprises monetize and grow.
