at HubSpot  Flex - London, United Kingdom

Overview

Join HubSpot as a Senior Backend Engineer - Empower SMBs to Grow with World-Class Technology. At HubSpot, we're on a mission to help small and medium-sized businesses (SMBs) thrive with our industry-leading CRM, Marketing, Sales, and Services products. As a Senior Backend Engineer on our dynamic product team, you'll have a direct impact on the growth of businesses around the globe, empowering them to serve their customers better.

We prioritize both our customers and our engineers. HubSpot dedicates about 20% of its engineering resources to building tools and platforms designed to help you concentrate on what you love. With a hybrid work model, you can work remotely anywhere in the UK or Ireland, or collaborate in London or Dublin as a Flex worker.

Responsibilities

• Write and ship impactful production code that directly contributes to user satisfaction and company growth
• Design, build, and evaluate new features and tools that drive revenue and help businesses grow
• Collaborate in a diverse, cross-functional team of engineers, PMs, designers, and researchers, where everyone's input is valued

• Help SMBs achieve their goals through enhancements you've brought to life in our products
• Gain a deep understanding of how HubSpot functions as a business, positioning yourself for personal and professional growth

Who You Are

We're not looking for specific tech stacks — we're looking for passionate problem solvers who are excited to make an impact. You might be a great fit if you:

• Have backend development experience and are comfortable with Java, MySQL, AWS, DropWizard, Kafka, Kubernetes, or similar technologies (expertise in specific tools isn’t a deal-breaker)
• Are deeply user-focused and empathetic, understanding the challenges our customers face and how they move through our product
• Enjoy tackling both technical challenges and business problems, and thrive when you're close to go-to-market strategies
• Collaborate well with others, take ownership of your work, and are eager to “figure things out” in a supportive, innovative environment
• Have demonstrated the ability to solve complex technical problems while weighing tradeoffs, with a deep understanding of developer experience and business needs
