Senior Frontend Engineer React.js/Typescript

Location: Stockholm (office-first, flexible)

Salary: Up to 70,000 SEK/month

Employment: Permanent

About the Company

This is a VC-backed technology company building a white-label Web3 platform within the iGaming space.

The product enables operators (e.g. streamers, influencers, brands) to launch and scale fully licensed online casino platforms without needing to build the underlying technology themselves. The platform handles complex areas such as payments, compliance (AML/KYC), licensing, and on-chain transparency.

The product is already live with paying customers and proven product–market fit. Following strong investment this year, the company is now focused on scaling the platform and growing an in-house engineering team in Stockholm.

The Role – Senior Frontend Engineer

The company is looking for a Senior Frontend Engineer to take significant ownership of the frontend as the product continues to scale.

The wider engineering team is largely full-stack with a backend focus, so this role will be frontend-led and highly influential. You’ll work closely with UX/UI and product stakeholders, shaping both the user experience and frontend architecture.

This is a key hire with a high degree of autonomy and a clear opportunity to grow into a lead role over time.

What You’ll Do

• Take ownership of frontend architecture and implementation
• Build and evolve complex, high-traffic user interfaces
• Work closely with UX/UI, product, and backend engineers
• Translate product requirements into scalable, maintainable frontend solutions
• Influence frontend standards, best practices, and technical direction
• Contribute across the stack when needed (start up environment)

Tech Stack

• React
• TypeScript
• Next.js
• Tailwind CSS

What We’re Looking For

• Senior-level experience as a frontend or frontend-focused full-stack engineer
• Strong hands-on experience with React, TypeScript, Next.js, and modern frontend tooling
• An eye for good UI/UX and frontend quality
• Experience taking ownership of features or entire frontend areas
• Comfortable building from scratch without heavy hand-holding
• Experience in product-led or high-traffic environments is a plus
• Pragmatic, collaborative mindset suited to a scaling start-up

Nice to Have

• Experience in Web3, blockchain, payments, or iGaming
• Full-stack experience (Node.js / APIs)
• Experience working with data-heavy dashboards or real-time systems

Ways of Working

• Office-first as the in-house team grows, with flexibility when needed
• Modern office near Stockholm Central Station
• You won’t be the only engineer in the office, product, data, and engineering roles are already based there
• Existing remote engineers will remain remote; new hires are ideally Stockholm-based

Why This Role?

• VC-backed company with strong financial runway
• Live, revenue-generating product with validated market fit
• Interesting technical challenges: high traffic, large data volumes, on-chain transactions
• High degree of ownership and autonomy
• Clear opportunity to grow into a Frontend Lead / Tech Lead role
• Unique product in a fast-growing, technically complex domain

Interview Process

1. Initial technical discussion with engineers (no coding test)
2. Conversation with the CTO (experience, mindset, culture)
