Frontend Product Engineer to Bryntum

Om tjänsten

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.

Bryntum is now looking for a Frontend Product Engineer who understands exactly what that means and wants to own those decisions.

About the role This role covers product strategy, prioritization and backlog ownership as well as hands-on frontend development. You are a developer who is driven by product questions and strategy. You keep track of incoming requests and bugs, hold the big picture together without losing sight of the details. You turn real feedback from our active developer community into improvements that balance long-term direction with short-term delivery.

Our customers are developers, not end users. You'll read bug reports, screenshots and code snippets and translate them into improvements that actually matter. We also want you to build a tighter feedback loop directly with customers, to learn how people actually use and experience our product.

What we're looking for

• 8+ years of experience as a frontend developer, with strong skills in JavaScript/TypeScript and modern frameworks (React, Angular or Vue)

• Experience taking product ownership for what you build, 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: specs, product documentation and clear requirements

Meritorious Experience from an SDK or component library company is a plus. A big bonus is comfort and ambition around modern AI coding tools such as Claude Code or Codex, it's something we genuinely care about.

Fluent English is a requirement, Swedish is a plus.

Who you are To thrive in this role, you're genuinely tech-curious, someone who loves having many touchpoints and brings real ambition to everything you take on. You will make decisions that affect thousands of production systems. You listen, read the room and know how to handle demanding customers in a way that builds relationships. You're comfortable with high ownership and like keeping things organized. You enjoy working independently and act proactively even in uncertain situations.

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
