About the Position

Frontend Product Engineer to Bryntum

What do UEFA's Euro championship, Red Bull's marketing operations, and Coca-Cola's production planning have in common?

They are all powered by Bryntum's JavaScript components.

Our components (Gantt, Scheduler, Calendar, Grid) live embedded in business-critical systems at 5,000 companies across 80 countries. That puts extreme demands on every release, every API decision, and every trade-off.

• Experience taking product ownership, shaping requirements, prioritizing work, and driving technical decisions.
• Experience with API design and backwards compatibility.
• Experience leading technical customer conversations and product discussions in English.
• Strong written communication skills: specs, product documentation, and clear requirements.

Nice to Have

• Experience from an SDK or component library company is a plus.
• Comfort and ambition around modern AI coding tools such as Claude Code or Codex.
• Fluent English, Swedish is a plus.

We Offer

• 6 weeks of vacation
