Jobs JavaScript / Front-End

About the Role

We're working with a company building secure infrastructure for enterprise blockchain and cryptographic systems, including multi-party computation (MPC) technology. The team is expanding its frontend capabilities and is actively moving toward agentic and AI-assisted engineering workflows.

The right person will step into a lean, self-directed engineering group and take real ownership over how the frontend is built, structured, and maintained across several products. One of the current priorities is connecting the company's digital-asset platform with a US banking partner, which involves building tokenized-dollar features and weaving the product experience into the bank's existing systems.

What We're Looking For
 

Core Technical Background

• Solid, senior-to-expert-level commercial experience in frontend engineering.
• Deep expertise in TypeScript/JavaScript and React.
• Strong Next.js background and a real understanding of modern frontend architecture.
• Hands-on experience with agentic or AI-assisted development that goes beyond simple code generation or casual "vibe coding."
• Practical testing experience: Playwright for end-to-end, and Jest, Vitest, or similar for unit/component testing.
• Comfortable with GitHub, GitHub Actions, and modern CI/CD practices.

• A security-minded approach to engineering, especially for sensitive or regulated products.

   

Nice-to-Haves

• Familiarity with Web3/blockchain concepts and associated security considerations.
• Background in FinTech or financial services products.
• Experience deploying on Vercel.
• Some exposure to TanStack Start.
• Comfort with AWS and containerized, cloud-agnostic setups.

• Time spent in regulated environments or those aligned with SOC 2 standards.

   

Domain Exposure

• Web3/blockchain knowledge is a strong plus but not mandatory if you show genuine curiosity and can pick up the domain quickly.
• FinTech or financial-services experience works well as an alternative or complementary background.
• Comfortable working in small, fast-paced product teams where engineers have a lot of autonomy.
  
   

What You'll Do

Frontend Development

• Build senior-level features across the product lineup.
• Write maintainable, scalable interface code in TypeScript, React, and Next.js.
• Turn loosely defined or high-level requirements into working solutions without needing fully detailed tickets.
• Weigh in on architectural and technical design choices for the frontend.
   

AI-Assisted / Agentic Development

• Contribute to building out mature practices and guardrails around agentic and AI-assisted engineering.
• Apply AI tooling to speed up delivery while keeping code quality, maintainability, security, and test coverage intact.
• Help introduce sensible checks and balances as AI-assisted practices spread across both frontend and backend teams.
   

Quality, Testing, and Security

• Thoroughly test your own code, covering both unit/component and end-to-end scenarios.
• Partner closely with QA throughout releases and support strong engineering practices overall.
• Stay alert to Web3-specific and general application-security risks, particularly those relevant to digital-asset products.
   

Technical Mentorship and Product Thinking

• Offer technical guidance and mentoring to a Cayman-based frontend colleague, without formal management authority.
• Bring a product-oriented mindset and make sound delivery calls when requirements aren't fully fleshed out.
• Independently dig into unfamiliar product or Web3 topics and come back with workable solutions to ambiguous problems.

- Contribute to code quality through reviews and shared standards, keeping our codebases scalable, maintainable, and reusable;
- Contribute to the design and implementation of new features, UI components, and in-game effects;
- Improve our core framework, build tools, and asset pipelines;
- Profile performance and debug across platforms (desktop, mobile, WebGL) to keep games running smoothly everywhere;
- Treat knowledge as a team asset — document your work and share what you learn with the team;
- Stay curious about modern frontend technologies and trends in the iGaming ecosystem.

💎 What you bring
- 4+ years of frontend development experience, including at least 2 years building HTML5 slot games — enough to have shipped multiple titles end-to-end and learned from real production cycles;
- Strong expertise with Pixi.js and modern JavaScript / TypeScript;
- Solid understanding of OOP, asynchronous programming, and rendering performance optimization;
- Strong knowledge of Spine animations and deep understanding of asset management pipelines;
- Experience with Vue 3 or other modern UI frameworks;

If you're a motivated Junior+ Front-end Developer looking for your next step, we'd love to hear from you.

You'll own the interface that turns raw medical data into something a clinic manager can actually act on. Today most of that data lives in exports, internal reports and half-built screens - the product works, but the front-end has grown faster than it was designed. Your job is to build and clean up the part users touch: dashboards, patient and claims tables, filters, charts, reports.

This is a hands-on product role, not a lead role. You own your tasks end to end, architecture decisions are made together with the CTO.

About the company
A European product company building a data and analytics platform for the healthcare sector - clinics, medical networks and insurers use it to see what is happening with their patients, costs and operations in one place.

• On the market since 2022
• Team of 11-50 people
• Fully remote engineering team [to be confirmed]
• Product company, no outsourcing or client rotation

What you'll do

• Build and maintain front-end features of the platform in React + TypeScript
• Develop data-heavy UI: dashboards, charts, large tables, filters, export and reporting screens
• Integrate the front-end with backend APIs, handle async data, caching and error states 
• Turn Figma designs into clean, reusable components
• Use AI coding tools (Claude Code and similar) as part of your daily workflow
• Cover your code with tests and take part in code review
• Work directly with the CTO and the designer to clarify requirements before you build
• Take a task from description to production and keep it stable afterwards

Who we're looking for
Must have:

• 3-5 years of commercial experience with React
• Strong JavaScript and TypeScript
• Practical experience with state and server data management (React Query / Redux Toolkit / Zustand - any of them)
• Experience integrating REST APIs and building complex forms and data tables
• Experience with charts and data visualization libraries (Recharts, Chart.js, D3-based, or similar)
• Daily use of AI coding assistants in real work, with hands-on experience of Claude Code
• English at B2+ - you will talk to the CTO and the team directly, without a translator
• Ability to run your own tasks without daily check-ins, and to ask questions early when something is unclear

Nice to have:

• Experience connecting AI tools to external systems
• Figma-to-code integrations or similar
• Background in healthcare, medtech or fintech - any domain with strict data rules (GDPR, HIPAA, FHIR/HL7)
• Next.js, testing (Jest, React Testing Library, Playwright)
• Experience working with design systems

Soft skills:

• Ownership - the team is small, and nobody will chase you for status updates
• Clear written communication - most of the work happens async, across time zones
• Attention to data correctness - a wrong number on a medical dashboard is not a cosmetic bug

Conditions

• Remote, flexible working hours
• 29 days of PTO (18 working days per year plus all national holidays)
  10 paid sick days
• Free English classes with native speakers or Ukrainian teachers
• People-first management, minimal bureaucracy
