- Optionales Büro in Leeds
At Parallax, we celebrate the curious. The people who love getting stuck into tough challenges and building technology that genuinely moves the needle and demonstrates the art of the possible.
We’re looking for a Senior Software Engineer with a passion for building great products to join our growing team.
You’ll spend most of your time writing code, solving complex technical challenges, and working collaboratively with UX designers, engineers and others across multiple projects — with some of your time focused on improving how we deploy, scale, and monitor our applications.
Our clients are diverse, operating across multiple sectors and geographies, often targeting global audiences. We’re innovators at heart, we work with technology that we’re passionate and excited about and use it to produce software and products that our customers love.
Key Responsibilities
- Work as part of a cross-functional squad to design, build and ship high-quality digital products for our clients
- Take ownership of complex technical challenges — unpicking problems and proposing well-structured, pragmatic solutions
- Write clean, maintainable, and well-tested code in languages and frameworks such as Node.js, TypeScript, and React. We also use other open-source languages and frameworks.
- Contribute to estimates and technical planning alongside your team and the Client Lead
- Communicate clearly and confidently with both technical and non-technical people — from clients to internal stakeholders — to explain ideas, trade-offs, and recommendations
- Implement and improve CI/CD pipelines using GitHub Actions
- Support the design, deployment, and monitoring of cloud infrastructure - primarily on AWS (ECS, ECR, Lambda, CloudFront, RDS, etc.) and Azure (you don’t need to be an expert but being interested helps!)
- Promote strong engineering practices around code quality, automated testing, peer reviews, observability, and security and help instil a culture of quality and accountability in engineering.
- Collaborate closely with designers, product managers and QA to ensure solutions are user-focused, technically sound, and aligned with client needs.
Skills & Experience
What you need to have:
- A passion for technology and continuous learning
- Strong software engineering background with ideally 3+ years experience building and maintaining production systems
- Strong hands-on experience with modern JavaScript/TypeScript frameworks, especially Next.js, React and React Native, other languages like Python/C#/PHP, a bonus
- Excellent communication skills and emotional intelligence — able to collaborate effectively and adapt your style when working with technical and non-technical people
- A collaborative mindset. You enjoy working closely with UX designers, delivery managers, product managers and other engineers
- Confident problem-solver able to troubleshoot complex systems and guide others to effective technical solutions, while being able to balance quality with delivery
- Flexibility to adapt your technical approach to fit existing technology stacks and standards
- Proficient with CI/CD pipeline design and automation using tools such as GitHub Actions
- Passion for code quality, with a strong understanding of TDD, automated testing, and peer review processes
- Familiarity with security best practices in cloud environments
- Familiar with Agile/Scrum methodologies and iterative delivery in cross-functional teams
Nice to haves: (don't worry if you don't have any of the following experiences, we'd still like to hear from you)

- Curiosity about mentoring or progressing toward a Principal Tech Lead role
- Experience working with AWS and/or Azure cloud environments
