About Us

At Medius, we believe managing finance should be about strategy, not stress. That same mindset shapes not only the solutions we build, but also the culture we create for our people. We remove complexity, embrace innovation, and give our teams the freedom to focus on what truly matters — whether that’s transforming the future of finance with AI or finding balance to go home on time.

Founded in Sweden in 2001, Medius has grown from a local startup into a global leader in cloud-based spend management solutions. Today, thousands of organizations worldwide trust us to simplify accounts payable and spend management processes. Our journey has been driven by continuous innovation, a passion for technology, and above all — the people who make it happen.

We’re more than a software company. We’re a team of problem-solvers, innovators and collaborators working together to reinvent the category of accounts payable. Our solutions use Artificial Intelligence to eliminate manual work, bring clarity, confidence, and control, and empower finance teams of the future.

At Medius, our values guide how we work and grow together:

• Connect – We believe in the power of people—individually and collectively—and our success depends on understanding and respecting each other.
• Question – We enjoy the challenge of our work and the thrill of collaboration. We are not afraid to question ourselves and each other because we believe diverse perspectives can lead to better outcomes.
• Own – We are thorough, thoughtful, and decisive. We anticipate what’s next, what a customer might need, and then we deliver.

At Medius, you’ll join a diverse, global community where curiosity is celebrated, ideas matter, and innovation never stops. If you’re passionate about technology, eager to make an impact, and ready to grow alongside a team that lives its values, Medius is where you can do your best work — your impact is global.

Job overview

We automate accounts payable, invoicing, and payments for organisations that need precision and control over how money moves. We're in a significant period of product investment, with AI reshaping how we build, what we ship, and how our customers work. The design team is central to that, and this is a good moment to be part of it.

You will work as a product designer embedded in a cross-functional team, taking real ownership of feature design from problem framing through to shipping. This is a role where you'll move beyond execution and start developing your own design voice: forming views on what the right problem is, not just how to solve it.

Responsibilities and Duties

• Design features end-to-end: taking a problem brief, exploring solutions, building prototypes, and working with engineers through to delivery.
• Contribute to user research and usability testing, building confidence in running sessions and translating findings into design decisions.
• Use AI tools as part of your day-to-day practice, including Figma's AI features and generative prototyping.
• Work closely with a product manager and engineers as a full member of a squad, contributing to decisions beyond the design brief.
• Contribute to the Medius design system: following and improving patterns, flagging gaps, and helping maintain consistency across the product.
• Give and receive design critique in formal crits and async reviews.

Qualifications

• 2+ years of product design experience, ideally in B2B SaaS or fintech.
• Solid UX and UI foundations: you understand the research-to-spec journey and have done it.
• Proficient in Figma, including components, variants, and auto-layout.
• A genuine interest in AI, both as subject matter and as a craft tool.
• Clear communicator: able to explain design decisions to engineers and product managers and take feedback constructively.
• A portfolio that shows reasoning, not just finished work.

Nice to have:

• Experience designing for complex data workflows, approval flows, or financial products.
• Some exposure to design system contribution or component library work.
• Experience with AI-assisted design or prompt-to-prototype workflows.
