Senior Software Engineer – Front-End

At Speechmatics, we’re expanding our user platform offering. We're looking for a Senior Front-End Software Engineer with a strong product mindset to help drive that growth. This is an opportunity to own end-to-end feature development at a leading-edge AI company, from shaping the user experience through to shipping and iterating based on real user feedback and analytics data.

What you'll do

• Own product features from ideation through to delivery, contributing to UX thinking, frontend execution, and post-launch iteration
• Build polished, accessible user interfaces using React, JavaScript, HTML, and CSS
• Make UX and UI decisions independently, collaborating closely with designers and PMs rather than waiting on detailed handoffs
• Design and run A/B tests to validate product decisions and surface insights that improve the user experience
• Use analytics tooling such as Mixpanel to understand how people interact with the product and feed that learning back into what gets built
• Partner with backend engineers, product managers, and designers to ship features that genuinely move the needle for users and the business
• Write and maintain robust UI tests, taking ownership of quality in production and at scale
• Run user interviews and meet customers to understand how people use the product and what drives adoption

What you'll need

• Proficiency in React, JavaScript, HTML, and CSS with a track record of shipping production-quality frontend code
• A product-minded engineering approach
• Comfort owning UX and UI decisions independently
• Hands-on experience with iterative development practices, including A/B testing and feature experimentation
• Familiarity with user analytics tools such as Mixpanel or a comparable platform
• Experience with UI testing frameworks and a solid grounding in frontend engineering best practices
• Confidence collaborating cross-functionally with designers, PMs, and backend engineers
• A track record of using user feedback and data to improve features

Nice to have

• Experience using coding agents (eg Claude, Codex, OpenCode) to improve productivity and code quality
• Exposure to backend development, including RESTful APIs and cloud deployments
• Experience conducting or participating in user interviews as part of a product discovery process

From Private Medical, and Dental for you and your family, through to global working opportunities, a generous holiday allowance and pension/401K matching, we want to make sure our employees and their families are looked after. Every employee will receive a working from home allowance for tech or home office equipment (on top of your choice of laptop and accessories of course). Our approach to parental leave is designed to support employees globally. While this varies by geo, we have support in place for parents (including adoption assistance and reproductive health services) to ensure they have the time and financial resources needed to care for their growing families.

But we don’t just open the door to diversity – we actively welcome it. Why? Because we believe every unique voice adds something special to our team, leading us to smarter solutions and a better workplace.

So, come as you are and join our Speechling community. We’re building a place where every voice not only gets heard but is also respected and valued.
