Senior Fullstack & DevOps Engineer to Bryntum

Bryntum's JavaScript components for scheduling, planning and operations are embedded in business-critical systems at 5,000 companies across 80 countries. Microsoft, Netflix, SpaceX and BMW to name a few. Keeping that infrastructure reliable, secure and scalable is the foundation everything else rests on.

That's where you come in.

Bryntum is looking for a Senior Fullstack & DevOps 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 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

What we're looking for someone that has:

• 6+ years of experience as a fullstack engineer with strong exposure to DevOps, platform or infrastructure work
• Solid experience with AWS, Docker, and cloud infrastructure
• Strong scripting and automation skills, Node.js and Bash in particular
• Experience managing virtual server environments
• A methodical, detail-oriented approach, this is a trust role with access to production

Meritorious
What matters is that you're curious of new technology and can get up to speed quickly. Experience using AI tools like Claude Code for scripting, debugging or operational workflows is a big plus. We're interested in people who actively use modern tools to move faster and reduce manual work.

Fluent English is a requirement, Swedish is a plus.

Who you are
You're driven, take pride in your work and set a high bar for yourself. You enjoy working independently and act proactively even under uncertainty. You're the kind of person who spots a problem and fixes it. You find it genuinely satisfying to keep systems clean, stable, and well-organized.

What we offer

• 6 weeks of vacation
• ITP pension and insurance
• Wellness allowance
• Freedom with responsibility. You own your day as long as the work gets done
• Hybrid model with a Stockholm hub at Epicenter
• One joint team trip per year where the whole organization comes together
