Location: UK & Ireland
We’re looking for a Senior Frontend Software Engineer to help us scale and evolve a fast‑growing notifications platform. This is a new role, opened to increase capacity as the team builds on a recently launched first phase and moves quickly into its next stage of development.
You’ll work primarily on the frontend, building high‑quality, user‑facing experiences that sit at the heart of customer engagement. This role is ideal for someone who enjoys ownership, working in new problem spaces, and shaping systems that operate at massive scale.
About the TeamThe Notifications team owns a central platform that powers how customers are engaged across HubSpot. Our mission is to build a unified engagement platform that delivers the right message, at the right time, through the right channel, while actively reducing noise and spam.
We work on high‑impact areas such as in‑app notifications and pop‑ups. Under the hood, this includes evolving an existing platform and building new capabilities, including smarter decision making and a recommendation engine that helps teams serve customers more effectively.
Notifications are one of the biggest points of contact between HubSpot and its customers with millions being sent every day, which makes this a uniquely high‑scale, high‑responsibility area to work in.
What You’ll Do- Design, build, and maintain frontend features using React and TypeScript
- Evolve a newly launched notifications platform as it scales to millions of daily interactions
- Partner closely with product managers, designers, and backend engineers to deliver cohesive user experiences
- Help reduce notification noise by building smarter, more intentional engagement patterns
- Contribute to technical direction, frontend architecture, and best practices across the team
- Review code, mentor teammates, and raise the overall quality bar of the frontend codebase
- Participate in async‑first collaboration, with clear communication and timely feedback
In the first few months:
- You’re shipping production frontend code confidently
- You understand the notification ecosystem and customer impact deeply
- You’re contributing ideas to improve usability, performance, and scalability
After one year:
- You own major areas of the frontend experience within the notifications platform
- You influence technical decisions and frontend standards
- You’re helping shape how HubSpot engages customers at scale
- You’ve grown in scope, impact, and leadership
- Strong experience building frontend applications with React and TypeScript
- Solid understanding of frontend architecture, performance, and state management
- Experience working on products at scale, or a strong interest in doing so
- Comfort operating in ambiguous, fast‑moving problem spaces
- A collaborative mindset with a bias toward ownership and impact
- Massive scale & visibility: Millions of notifications sent daily across critical customer touchpoints
- High impact: Your work directly affects how customers experience HubSpot
- Greenfield energy: Build on a new platform that’s still being shaped
- Growth opportunities: A chance to grow technically and in scope as the platform and team expand
- Async‑friendly culture: Clear expectations with a 24‑hour SLA for responses and scorecards
