Role description

About Atira
Atira builds the commercial brain for industrials.
Our agents 10x the sales engineers of today by offering the complete toolbox of tasks needed in complex environments. They handle everything from extracting and classifying requirements from incoming RFQs, orchestrating communication and information retrieval across multiple stakeholders and systems, while generating outcomes like documentation, production system inputs, or configuration recommendations.
CRM. Atira. ERP.
We are one of the fastest growing teams in Munich and are looking for you to join us!

Why UX Engineers Are Foundational To What Atira Ships
As a UX / Front-End Engineer at Atira, you turn frontier AI from "demo-able" into "usable" inside the daily work of a sales engineer. Our agents handle some of the hardest workflows in industry: parsing 1000-page RFQs, reconciling specs against ERP tables, generating outputs that flow into SAP, Salesforce, and PLM systems. None of that matters unless a human can review, trust, and intervene in the agent's work at the right moment.

You will design and build the surfaces where agents and humans meet and interact: Chat with human-in-the-loop, document review UIs that render complex multi-modal inputs (tables, drawings, configurator rules), agent timelines and trace views, diff and approval flows, internal tooling for our FDEs and AI engineers, and the design system that ties it together.

A misread requirement can cost a manufacturer six figures, so the UI that surfaces that requirement to a human reviewer is crucial. The challenges are real and the margin for error is thin.

Where you trained matters less than what you've built and the taste you bring. Atira is at a stage where you must own problems end to end, because what you ship today is what our customers use tomorrow.

What You Will Do

  • Own the surfaces where agents meet humans. Chat with HITL, agent step-by-step traces, approval flows, inline reviewing, editing of agent outputs and generative UI. The best agentic functionality is only as good as its usability & the underlying user trust
  • Lead our frontend architecture and design. You will own our frontend architecture and be responsible for our team shipping UI / UX in a scalable, consistent framing
  • Render complex, data-heavy documents. Industrials live in 1000-page RFQs, Excel pricing lists, BOMs, technical drawings, configurator outputs. You'll build the UIs that make these reviewable, diffable, and editable without dragging the browser to its knees
  • Build full-stack features end to end. From the React component to the route to the API contract, you ship vertical slices. You partner with FDEs and backend engineers but you do not wait on them
  • Set the bar for craft. Motion, interaction, latency, polish. You define the design system, component primitives, and patterns the rest of the team builds on. You care that a button feels right, not just that it works
  • Reliability and tests. Playwright coverage on the flows that matter. You think about loading states, error states, empty states, and what happens when the agent stream stalls at token 4,732

What We Are Looking For
Taste, depth, and taking problems personally, go deep until the interaction feels right, and own the outcome including the parts that broke.

Your profile

  • Very strong frontend fundamentals. Excellent TypeScript / React skills. You understand rendering behaviour, suspense, server components, concurrent features, and the gap between "code that works" and "code that won't haunt the next person." You can read someone else's production frontend, understand why it was built that way, and ship changes that make it more scalable
  • Strong taste. You understand and are opinionated around the right way of designing UI / UX to reduce user friction & unlock feature adoption
  • Experience with our stack or close alternatives: React, Next.js, the Tanstack ecosystem (Query, Table, Router and Start), Vite, Playwright. Tailwind, shadcn/ui, Radix etc.
  • You've gone further than most with AI-assisted development. Whether it's Claude Code, Cursor, Codex, or your own setup, you've invested seriously in building the skills, context, and workflows to get maximum leverage from coding agents
  • You are a strong technical decision maker who knows how to make tradeoffs on rendering strategy, state management, data fetching, and component architecture, and can explain the pros and cons of every solution
  • You've demonstrated ownership and initiative: a company you started, a serious open-source contribution (UI library, design system, real commit history), a side project that grew to production scale, or a role where you owned a user-facing surface that others would have delegated. We want to see evidence that you build things without being told to
  • Degree in Computer Science, HCI, Design Engineering, or a related technical field from a strong technical university, or an equivalent record of shipped work
  • Full working proficiency in English. German is not required

What you'll get

  • Real ownership: you'll be one of the early team members and shape both product and architecture, while working closely with customers
  • Strong peers: work with people who have built and shipped AI systems in industrial environments at scale before, and the chance to learn directly from them
  • Impactful work: your code is deployed all across Europe's and the US's industrial backbone, affecting how complex products and services are sold and configured worldwide
  • Competitive salary & equity package and additional benefits including Wellpass, JobRad, and company dinners
  • Most importantly: collaborate and thrive in a high-performing but caring culture. We will own the industrial sales function but will do so with modesty and integrity

What Success Looks Like After a Few Months

  • You've shipped the agent and human interaction surfaces that customers spend their day in, and FDEs cite them as a reason deals close faster
  • You own a core surface (chat, document review, agent trace, internal tooling, the design system) and the team trusts your judgment on how it should evolve
  • When something breaks on the frontend, you can trace issues across React, Next.js or Tanstack Start, the API contract, and the backing services, and fix them end to end
  • The frontend is fast under real load: Your architectural decisions have held up and you can explain the tradeoffs you made and what you'd do differently

Frontend Engineer

Product Engineer — Working Student

SumUp

Berlininternship

Apply on the employer's site

Role description

Working Student - Product Engineer
Over 4 million merchants use our card readers to process payments in 34 countries. As we build a world where every business can thrive, we continually expand our range of products and services. We are a truly global fintech company, with 3,000+ people from 93 nationalities spread across 22 offices on four continents.

As the People Tech team, our mission is to enable long-term scalability by fostering a data-informed culture through seamless systems and a people-centric employee experience. As our Product Engineer - Working Student, your first mission will be to help us rethink Feedback and Team Reviews: learn how the process works today, find the friction and turn promising ideas into product experiences that colleagues can test.

The work starts frontend-first: build realistic prototypes in React, Next.js or similar and explore a simpler product layer over Workday, our system of record. If a direction proves valuable, you may help grow it into a standalone internal app - from interface and APIs to data models, authentication and integrations - alongside People Tech and engineering partners.

This is a real product challenge, not a side quest: you will learn across discovery, UX, frontend, testing and product decisions, supported by mentorship and code review. You will collaborate with Product Owners, process owners, people tech and workday specialists, sumuppers, managers, people partners, people analytics and senior stakeholders, with potential exposure to backend development, integrations and production delivery. If your favourite way to answer “what if?” is to build it, you will fit right in.

What You’ll Do

  • Find the right problem: Speak with process owners, employees and managers to understand Feedback and Team Reviews, identify friction and decide what is worth solving first.
  • Shape a focused product slice: Turn requirements, questions and constraints into clear user journeys and an MVP that can teach us something useful.
  • Prototype and iterate quickly: Build realistic frontend experiences in React, Next.js or similar; compare directions, test assumptions and adjust when the evidence points somewhere better.
  • Design for different kinds of work: Create accessible, intuitive flows for office-based teams, metrics-driven Field Sales colleagues and on-site teams without building three separate products.
  • Think end to end: If the concept is validated, help evolve it towards a standalone app while considering APIs, data, authentication, privacy, deployment, integrations and what should remain in Workday.
  • Use AI as a co-pilot, not an alibi: Use tools such as Cursor, GitHub Copilot, v0, Lovable or similar to accelerate development while still understanding, checking and owning the result.
  • Make the learning visible: Demo your work, explain decisions and trade-offs, respond to feedback and document the findings and technical choices that should shape the next version.

You’ll be great for this role if

  • Student status. You are currently enrolled at a university and available for a part-time role based in Berlin.
  • Modern web development skills. You have built web applications with React, Next.js or a similar frontend framework. Coursework, internships, hackathons, personal projects and portfolio work all count.
  • Product-minded builder. You care about the user’s goal and accessibility, and can turn an ambiguous problem into the simplest useful solution, test it and iterate.
  • Full-stack and AI curiosity. You want to learn how APIs, data and services turn an interface into a reliable product, and can use AI-assisted tools while still understanding, checking and owning the result.
  • Clear, team-first communication. You can explain what you built end to end, make technical choices understandable, ask for input and respond well to feedback.

Nice to have

  • Backend and integration foundations. Some experience with Node.js, TypeScript, Python, databases, APIs, serverless functions, Supabase, Firebase, AWS or comparable technologies.
  • Identity and data concepts. A basic understanding of OAuth, SSO, permissions or responsible data handling.
  • What we don't expect: years of professional experience, previous Workday knowledge or a perfect first attempt. If you do not tick every box, please apply anyway and show us what you can build, how you think and how you learn.

Job Application Tip
We recognise that candidates feel they need to meet 100% of the job criteria in order to apply for a job. Please note that this is only a guide. If you don’t tick every box, it’s ok too because it means you have room to learn and develop your career at SumUp.
