Job Description, Responsibilities & Requirements
About the Position
Bryntum’s components are used in applications at thousands of companies worldwide, for scheduling, planning and operations. Those systems depend on infrastructure that is reliable, secure and easy to maintain.
That's where you come in.
Bryntum's JavaScript components are embedded in business-critical systems at 5,000 companies across 80 countries. Keeping that infrastructure reliable, secure and scalable is the foundation everything else rests on.
Bryntum is looking for a Senior Platform Engineer who takes that responsibility and wants to help us build for the next phase of growth.
About the Role
You'll join a small Platform and Infra team and take on a broad role spanning development, operations and infrastructure. You'll work fullstack, from database to frontend, while sharing ownership of the AWS environment and the systems our customers depend on. Alongside two colleagues, you'll have access to production servers and the systems that keep Bryntum running. We need someone who is thorough, dependable, and takes pride in doing things properly.
The role covers everything from building and maintaining internal tools, customer zone and back-office systems, to driving our cloud journey forward. We need someone who is comfortable moving across the stack and isn't afraid to roll up their sleeves on whatever needs attention. Whether that's writing application code, scripting automation or shaping our deployment setup.
We're in the middle of a maturity journey: moving towards AWS, consolidating infrastructure and replacing ad hoc solutions with more robust setups. You'll be part of shaping that transition alongside your colleagues, with real ownership over the decisions you make.
