Title : Senior Full Stack Developer

Cognizant is one of the world's leading professional services companies, transforming clients' business, operating, and technology models for the digital era. Our unique industry-based, consultative approach helps clients envision, build, and run more innovative and efficient businesses. Headquartered in the U.S., Cognizant (a member of the NASDAQ-100 and one of Forbes World's Best Employers 2025) is consistently listed among the most admired companies in the world.

This role is part of Cognizant IOA (Intelligent Operations and Automation) and more specifically, a product team with its own origin story. We started as Matterway, a German startup building automation software from scratch. We were acquired by Cognizant, but we kept our team, our culture, our pace, and our way of working. We move like a startup, think like a startup, and now do it with the backing of a global company.

We combine human expertise with intelligent automation, ML operations, and digital experience solutions to help technology and digital-native companies build smarter, more adaptive operating models.

What's the opportunity?

We are looking for Senior Product Engineers to join our team. We're a tight crew of 4 engineers, all sharp, all from different corners of the world. We're doubling : hiring 4 more people, and those people will shape what this team becomes.

We're building a platform to support the agentification of our operations. You'll work across a suite of products including a cloud platform for process optimization, AI coding agents, and specialized AI agents. This is genuinely frontier work: we don't follow AI trends, we implement them. New model drops on a Monday, we've prototyped with it by Wednesday.

We believe this is the most exciting time to join. Be part of the founding R&D talent in this area, and help set the technical bar for everything that comes next.

Your day-to-day responsibilities :

- Participate in the full development lifecycle: scoping, design, estimation, coding, testing, debugging, code reviews, maintenance, and support

- Evaluate and implement proofs of concept using the latest AI tools and models

You will know you're successful if :

- You develop projects independently until they deliver their intended business value

- You keep top-notch software quality standards in regard to design, implementation and documentation

Nice-to-haves :

- Experience in frontend development using JavaScript and modern frameworks such as Vue.js or React

- Experience with Puppeteer or Playwright

- Familiarity with AI-coding tooling (Claude Code, Cursor, Open Code, etc.)

Why join us?
