Matillion is The Data Productivity Cloud. We are on a mission to power the data productivity of our customers and the world, by helping teams get data business ready, faster. Our technology allows customers to load, transform, sync, and orchestrate their data.

We are looking for passionate, high-integrity individuals to help us scale up our growing business. Together, we can make a dent in the universe bigger than ourselves.

About the Role

The Principal Frontend Engineer has responsibility for the Matillion Codebase and its design. Their primary responsibility is to ensure longevity of the product architecture as it grows and evolves to better support work done by multiple independent teams. They work to ensure a consistent and repeatable approach is employed by all members of the engineering team in the implementation of code.

We value in-person collaboration here at Matillion, therefore this role will ideally follow our hybrid work structure where employees work 2 days a week in the Manchester office. However, we can be flexible for the right person.

What you will be doing

1. Collaborate with Product and Engineering leadership to develop and execute a high-level product roadmap, ensuring alignment with business goals.
2. Design, prototype, and validate scalable front-end architectures, working closely with the Architecture team, Senior Developers, and Product Managers.
3. Own architectural decisions, balancing innovation with maintainability, while identifying and addressing codebase inefficiencies, bottlenecks, and security vulnerabilities.
4. Support development teams in creating modular, reusable front-end components and optimizing performance across the product range.
5. Act as a technical mentor, fostering skill development, encouraging technical discussions, and promoting best practices within the team.
6. Work cross-functionally with Testing, Delivery, and Site Reliability teams to ensure efficient development, testing automation, and smooth deployment processes.

What we are looking for

1. Expert-level proficiency in React and TypeScript, with a deep understanding of the broader frontend ecosystem, including state management (Redux, Zustand) and performance optimization.
2. Strong experience in architecting and implementing scalable, real-time, event-driven applications using WebSockets, SSE, and micro-frontend architectures.
3. Proven ability to design and develop secure, high-performance frontend applications, with hands-on experience in profiling, logging, and monitoring large-scale systems.
4. Experience working closely with UX designers to create accessible, user-friendly interfaces, including implementing design systems and component libraries.
5. Demonstrated leadership in delivering complex software projects, influencing stakeholders, and driving best practices in testing strategies and agile methodologies (Kanban, Scrum).
6. Solid understanding of cloud platforms (AWS, GCP, Azure), databases, and messaging-based integrations, with hands-on experience refactoring and scaling large codebases.

At Matillion, we are committed to providing competitive salaries in line with market standards. Our estimated compensation range for this position is £93,600 - £140,400, but the final salary will be based on your relevant skills, experience, and qualifications demonstrated in the hiring process.

Matillion has fostered a culture that is collaborative, fast-paced, ambitious, and transparent, and an environment where people genuinely care about their colleagues and communities. Our 6 guiding principles shape how we work together and with our customers and partners.

We operate a truly flexible and hybrid working culture that promotes work-life balance, and are proud to be able to offer the following benefits:

• Company Equity
• 30 days holiday + bank holidays
• 5 days paid volunteering leave
• Health insurance
• Life Insurance
• Pension
• Access to mental health support
