Senior Backend Engineer | London | Scale-up, DTC & E-commerce Tech
I'm hiring for a fast-growing tech company that's changing how leading DTC and e-commerce brands reach the customers they struggle to get through to: the ones who ignore emails, scroll past retargeting ads and don't respond to SMS.
Their platform plugs straight into tools like Shopify and Klaviyo, and it's already delivering measurable incremental revenue for some of the best brands in the world. Now they need a Senior Full Stack (Backend) Engineer to help shape the architecture behind it.
What you'll be doing:
Designing and building robust, scalable backend systems
Architecting infrastructure for job processing, analytics and event tracking
Building internal tooling for rate limiting, quotas and authentication
Developing and maintaining APIs and backend services
Working closely with product, design and customer experience to ship great features
Owning your work end to end: code, infrastructure, tests and monitoring
What you'll bring:
4+ years building production-grade backend systems
Strong Python and TypeScript
Experience with AWS (ECS, SQS), Docker and GitHub Actions
Postgres and Redis
Experience with high-throughput systems or background job queues
A passion for clean, maintainable code and great developer experience
Nice to have: rate limiting or auth systems, analytics and attribution engineering (dbt, Snowflake), WYSIWYG editors, PDF generation and render jobs, SSR frameworks (Next.js, Remix)
📍 On-site, 5 days a week, London
