Staff Software Engineer, Backend Stream powers real-time Chat, Video, Activity Feeds, and AI Moderation for more than 1 billion end users across 4,000+ apps, from Strava and Bumble to eBay and Patreon. Our platform processes billions of API requests per month and supports applications with millions of concurrent users, while delivering highly reliable, low-latency services and a outstanding developer experience. We’re looking for Staff Software Engineers . You’ll join our Chat or Activity Feeds team and own backend systems that thousands of developers build their products on, from how they’re structured to how they scale. This is a full-time role based in our Amsterdam (visa & relocation support possible), Toronto, or Skopje office. We are also open to hiring the right person remote from the EU. Maybe you led a team for a few years and chose to go back to hands‑on work. That’s welcome here: this is an individual contributor role, and you’ll write code and touch databases yourself. You won’t enjoy it if you want to manage people, or if you’d rather stay away from infrastructure and database work. We’re also hiring Senior Engineers on these teams. If your experience fits Senior better than Staff, we’ll say so openly and talk it through with you. Extensive backend engineering experience, including technical leadership on systems in production. Proficiency in Go, Python, or in another backend language plus the willingness to switch to Go. Experience building features used by a large number of users, and scaling them as usage grows. Strong experience with a relational database. We use PostgreSQL, but any relational database counts. Hands‑on experience with Redis or a similar in‑memory data store. Experience building public APIs or SDKs that other developers use. Comfort with infrastructure and database work as part of your normal week, including Kubernetes. Good written and spoken English. It’s our working language. Bonus points PostgreSQL in production at scale, including sharding, partitioning or large migrations.



Experience improving or redesigning legacy parts of a system that’s serving live traffic. Experience running workloads on GCP or AWS. Impact: cost per message and query latency show up directly in our margins and in the apps of customers like Strava and Patreon. Stack: Go, gRPC, RocksDB and Python; PostgreSQL and RabbitMQ; Starting point: you’ll ship to production in your first weeks and own a meaningful area within your first months. Generous compensation Amsterdam office

benefits:
~28 days paid time off plus Dutch public holidays. ~ Pension plan with a company contribution. ~ EUR 500 per year for personal development. ~ Catered lunches in the office. ~ Relocation support if you move to Amsterdam, including visa sponsorship as a recognised IND sponsor. Toronto, Skopje and remote EU: local benefits depending on your country of employment. We’re backed by Felicis Ventures, GGV Capital, 01 Advisors, Techstars, and Arthur Ventures, with angels including Dick Costolo (ex‑CEO of Twitter), Olivier Pomel (CEO of Datadog), Tom Preston‑Werner (co‑founder of GitHub), and Nicolas Dessaigne (co‑founder of Algolia). We’ll be straight with you: a startup is more demanding than a large company. If you want real ownership and high scale more than structure and a set career ladder, you’ll feel at home here.
