Job description

Job Description
About us- Cognex is the largest, most successful and recognized global player in industrial machine vision! We are a financially strong, international company with no debt and have been in business for over 40 years. Using advanced optics, image sensors and artificial intelligence software Cognex vision and ID systems capture an image then analyze it to make sense of what's being seen. We are deeply committed to fostering an inclusive and equitable work environment, guided by our "Work Hard, Play Hard, Move Fast" culture, which celebrates employee innovation, determination, and dedication in a dynamic, fun, and distinctive atmosphere.
We are working on a hybrid schedule, 3 days in the office, 2 at home.
We are looking for a Senior Frontend Software Engineer to join our engineering team. In this role, you will design and build intuitive, high-quality user interfaces that power industrial automation systems used by customers around the world. You will take ownership of the frontend experience - crafting responsive, maintainable, and user-focused web applications - while collaborating closely with backend engineers to deliver end-to-end solutions.
If you enjoy building polished user interfaces, care deeply about user experience, thrive in an Agile environment, and are open to contributing across the stack when needed, we'd love to hear from you.
What You'll Do
  • Lead the design, development, and evolution of frontend-focused web applications using Angular (v14+).
  • Own and improve frontend architecture, design patterns, and technical standards across multiple applications.
  • Build responsive, accessible, and highly intuitive user interfaces for industrial automation solutions.
  • Collaborate closely with backend engineers to design and integrate frontend applications with Python-based APIs.
  • Drive UI/UX quality through performance optimization, maintainability, and accessibility best practices.
  • Write and champion unit, integration, and end-to-end (E2E) tests to ensure long-term reliability and confidence in releases.
  • Provide technical leadership through code reviews, design discussions, and mentoring of junior and mid-level engineers.
  • Partner with designers, product owners, and global engineering teams to translate complex requirements into elegant solutions.
  • Influence CI/CD pipelines, DevOps practices, and tooling to improve development velocity and software quality.
  • Actively participate in Agile/Scrum ceremonies, helping shape sprint goals and technical execution.
  • Balance delivery speed, technical excellence, and thoughtful user experience to produce high-impact results.

What You Bring
  • Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent experience).
  • 5+ years of experience building modern frontend web applications, with demonstrated technical leadership.
  • Deep expertise in Angular (v14+), TypeScript, HTML, and CSS, including advanced patterns and performance optimization.
  • Strong understanding of UI/UX principles and responsive design.
  • Proven experience designing and maintaining scalable frontend architectures.
  • Extensive experience with automated testing strategies and frontend test frameworks.
  • Solid experience integrating frontend applications with backend APIs and distributed systems.
  • Comfort working in Agile/Scrum environments and collaborating across disciplines.
  • Experience with development tools such as Jira, Bitbucket/Stash, TeamCity, and Confluence (or similar).
  • Excellent communication skills, a strong sense of ownership, and a collaborative mindset.

Bonus Points For
  • Meaningful experience contributing to backend services using Python (e.g., FastAPI).
  • A passion for automation, data visualization, or machine vision technologies.
  • Experience working with distributed or international teams.

Why You'll Love Working Here
At Cognex, our culture is built on ten core values - from Customer First to Fun - and you'll see them in action every day. We take pride in what we do, celebrate our wins, and never stop pushing for excellence.
Here's what you can expect:
  • A hybrid work model with coordinated home-office days.
  • A dynamic, multicultural team that thrives on collaboration and creativity.
  • The chance to make an impact in a fast-moving, global technology leader.
  • Competitive compensation, performance recognition, and opportunities for growth.
  • A workplace that's serious about results - and just as serious about having fun.

Cognex believes in fair and equitable pay. A reasonable estimate of the base salary range for this role is 130,000 USD - 180,000 USD. Please note that actual salaries may vary within the range, or be above or below the range, based on factors including, but not limited to, education, training, experience, professional achievement, business need, and location. In addition to base salary, employees will participate in either an annual bonus plan based on company and individual performance or a sales incentive plan.
This position provides a comprehensive benefits package, including health, dental, and vision insurance; a 401(k) retirement plan with company matching; employer-paid disability, family leave, and life insurance; paid time off (including holidays); optional voluntary benefits; and recognition and wellness programs.
