Role description

As a Senior Software Engineer, reporting to the Engineering Manager, you will design, build, and evolve our customer-facing portal and related web experiences, delivering features and improvements that provide direct value to our users.

You will focus on the portal front end, responsive UIs, workflows, and integrations, while partnering with backend and platform teams. Where product direction includes intelligent capabilities, you will help surface AI-assisted experiences in the portal (e.g., integrating AI-powered APIs, copilot-style features, or ML-driven insights) with attention to usability, trust, and performance.

You are also expected to use AI-assisted development tools as part of your day-to-day work, responsibly and in line with team standards, to improve productivity, explore solutions, and ship quality code faster.

Key Responsibilities

  • Gather requirements, design, develop, test, and ship portal features while collaborating in a dynamic and results-driven environment.
  • Lead and contribute to portal development using React, TypeScript, and JavaScript, including component architecture, state management, routing, and integration with REST or GraphQL APIs.
  • Leverage AI-assisted development tools (e.g., coding assistants, generation, refactoring, or test suggestions) as part of the engineering workflow—while validating outputs, preserving security and privacy, and following code review and organizational policies.
  • Take an active role in mentoring junior engineers.
  • Make a direct impact on the success of WatchGuard as a company.
  • Participate in on-call rotation approximately once every 2 months.

Ideal Candidate Profile

  • 5+ years of professional front-end development experience, including substantial production experience with React.
  • Strong proficiency in TypeScript and modern JavaScript (ES modules, async patterns, typing for scalable UIs).
  • Comfort applying AI tools in the software development lifecycle (e.g., for implementation, debugging, documentation, or reviews), with sound judgment about verification, security, and intellectual property.
  • 2–4 years of experience with AWS or similar cloud platforms (e.g., front-end hosting, CDN, serverless APIs, or consuming cloud services from browser-based apps).
  • 3+ years of experience working with CI/CD pipelines.
  • Familiarity with infrastructure-as-code or deployment tooling (e.g., Terraform, Serverless, or Ansible) as it relates to environments and releases.
  • Experience with SQL and relational databases such as PostgreSQL or MySQL (e.g., understanding data models for portal features or working with backend teams on queries and performance).
  • A proven track record of success building cloud-based, highly automated systems and customer-facing experiences.
  • A desire to contribute to a collaborative engineering culture through mentoring and knowledge sharing.
  • An innovative and passionate spirit, an ability to overcome technical issues in a cooperative environment, a commitment to ship quickly, and familiarity with agile software development practices.
  • The ability to deal with ambiguity, communicate well with partner teams, and a compassionate understanding of the customer experience.
  • Proficiency in writing unit, integration, and end-to-end tests for front-end applications (and collaboration on API contracts where applicable).
  • A passion for building scalable and maintainable code that supports growth and future-proofing of systems.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
