Job description

This role focuses on building scalable high-impact tools and applications. The work spans mission-critical systems and offers the opportunity to shape foundational technology choices.

As a senior developer, you'll be expected to contribute across the full software development lifecycle—architecture development, deployment, and ongoing improvement. Collaboration, shared ownership, and delivering high-quality solutions are central to the team's approach.

We're looking for someone who thrives in a dynamic environment, is comfortable wearing multiple hats, and can flex between front-end, back-end, architecture, database design, code reviews, and beyond. You might occasionally work on unconventional systems (such as spreadsheet automations) to ensure workflows run smoothly.

The ideal candidate is technically strong, open to feedback, and willing to engage in thoughtful discussion and compromise to find the best outcomes. A fast learner who adapts to shifting business priorities will thrive in this role.

Responsibilities

1. Lead or contribute to full-stack development projects from design to deployment and maintenance.
2. Explore new tools and technologies and help integrate them into the tech stack when appropriate.
3. Apply best practices across front-end and back-end systems, including architectural decisions.
4. Conduct code reviews and support a culture of knowledge sharing.
5. Select appropriate testing strategies based on project complexity and risk.

Qualifications

• 10 years developing websites and web applications.
• Experience with core frameworks or similar technologies.
• Proficiency in modern HTML, JavaScript, and CSS.
• Experience with build tools such as Webpack or Grunt.
• Experience with API integrations (REST) and API testing tools.
• Experience with database systems such as MS SQL Server, BigQuery, and advanced SQL queries.
• Applied knowledge of web and mobile development best practices.
• Understanding of cross-browser compatibility issues.
• Understanding of programming fundamentals, development processes, and strategies (e.g., SDLC, software development models, database systems, TDD, unit tests, domain-driven design).
• Excellent verbal and written English communication skills.
• Team-oriented with strong interpersonal skills.
