About You
We’re looking for a Web3 Fullstack Engineer to build the layer where web2 and web3 meet. Our mission is seamless web2 ↔ web3 integration — letting players and developers interact with digital items and move them through their full lifecycle (mint, own, trade, transfer, redeem, retire) without ever having to think about which side of the chain they’re on. You’ll work across the whole stack: wallet-connected frontends, high-throughput backend services, and the smart contract and indexing layers that make on-chain items feel as fast and familiar as anything in web2.
This is a hands-on engineering role with broad ownership. A player buying an item with a credit card, a game granting an in-game asset, and a marketplace settling a peer-to-peer trade should all resolve to the same coherent item model — regardless of whether the item lives in a database, a custodial wallet, or on-chain. Making that experience invisible to the end user, and reliable for the developer, is the core of the job.
You care about product quality and developer experience as much as protocol correctness. You’re comfortable owning a feature end to end, reasoning about trust and custody boundaries, and making pragmatic calls about what belongs on-chain versus off-chain.

Responsibilities
Build Seamless Web2 ↔ Web3 Integration
— Design and ship the flows that let users move between traditional accounts/payments and on-chain wallets without friction: custodial and non-custodial wallets, account abstraction, gasless transactions, and fiat on-ramps.
Own the Digital Item Lifecycle
— Build the systems behind item mint, ownership, transfer, trading, and redemption — keeping on-chain state and off-chain records consistent, auditable, and fast.
Develop Fullstack Features
— Deliver end to end across wallet-connected frontends, backend services, and the smart contract / indexing layer that powers item ownership and turnover.
Model Items & Ownership
— Design data models and APIs that represent items uniformly whether they live off-chain, in a custodial wallet, or on-chain, and keep them in sync.
Ensure Reliability of Value Flows
— Anything that moves items or money must be correct under failure: idempotency, reconciliation, replay safety, and clear recovery paths.
Integrate Blockchains & Marketplaces
— Interact with EVM chains, token standards, indexers, and marketplace/settlement flows; abstract their differences behind clean internal interfaces.
Collaborate Across Teams
— Work with product, security, payments, and game-facing teams to turn business needs into well-scoped technical plans, and document decisions so they stand on their own.
What You Bring
Web3 & Digital Assets
Web2 ↔ Web3 Integration
— Hands-on experience bridging traditional systems with on-chain ones: wallet onboarding, custodial vs. non-custodial trade-offs, account abstraction, gasless/relayed transactions.
EVM & Smart Contracts
— Working knowledge of EVM chains and Solidity, including reading, integrating with, and reasoning about the safety of contracts.
Token & Item Standards
— Practical understanding of ERC-20, ERC-721, and ERC-1155, and how they map to real game items, ownership, and transfers.
On-chain / Off-chain Sync
— Experience keeping blockchain state consistent with off-chain databases: indexing, event ingestion, reorg handling, and reconciliation.
Frontend Engineering
TypeScript & React
— Strong TypeScript and React skills for building responsive, production-grade interfaces.
Wallet Integration
— Experience with wallet connectivity and web3 client libraries (e.g. wagmi, viem, ethers.js, WalletConnect) and embedded/social login wallets.
Backend Engineering
Backend Services
— Solid backend skills in Node.js and Go: clean APIs, concurrency, and performance under load.
Distributed Systems
— Experience with distributed systems and their trade-offs (consistency, availability, failure modes), especially where correctness of value transfer matters.
Data & Infrastructure
PostgreSQL
— Schema design, query optimization, and migrations at scale.
Kubernetes
— Deploying, operating, and debugging services in a k8s environment.
Message Streaming
— Kafka or NATS — event-driven patterns, consumer groups, at-least-once delivery.
Git & CI/CD
— Git and modern CI/CD practices.
Domain Context
Gaming Industry Experience
— Experience building or operating platforms for game developers, publishers, or players — especially anything touching in-game items, economies, or ownership.
Nice to Have
Experience building NFT marketplaces, item trading, or secondary-market / settlement systems
Familiarity with blockchain indexing tooling (The Graph, custom indexers) and node/RPC infrastructure
Experience with account abstraction (ERC-4337), smart wallets, or paymaster/relayer setups
Background in payments or fiat on-ramp integration bridging traditional commerce and crypto
Experience with non-EVM ecosystems (Solana, etc.) or cross-chain / bridging patterns
Familiarity with security and compliance relevant to digital assets: custody, key management, audit logging, KYC/AML touchpoints
Contributions to open-source web3, wallet, or tooling projects
Hands-on, up-to-date experience with modern AI tools (e.g. Claude, Copilot, Cursor) for code generation, review, and accelerating day-to-day engineering work
Benefits
We are passionate about fostering a supportive environment for our team, so we prioritize the physical, mental, and emotional well-being of our employees through a comprehensive Benefits Program. This includes unlimited Flexible Time Off and a personalized career roadmap for each employee. By investing in professional development through training and educational opportunities, we ensure that our team thrives both personally and professionally.

Our Engineering Culture
We believe that "Simplicity is a prerequisite for reliability." We are looking for engineers who align with our core values:
- Simplicity: We avoid over-engineering. We prefer the tools we already have and the most straightforward solutions over "shiny new toys."
- Quality: We write code that is a pleasure to read because we know code is written once but read many times. We don't cut corners, and we polish to a high level before shipping.
- Extreme Ownership: We don't just do the minimum. We expect you to understand the "why" behind your work and own the ultimate goal of fixing problems at their root cause, avoiding temporary band-aids.
- Prioritization: We focus relentlessly on what is important, not just what is urgent.

WHO ARE WE?
Welltech is a global wellness technology company with Ukrainian roots. Our mission is to build and scale wellness apps globally through state-of-the-art, tech-driven performance marketing.
We are one of the most established players in the wellness app space, and we are accelerating. Over 25.5 million people across the world use our apps — Muscle Booster, Yoga-Go, and WalkFit — to build healthier habits, move more, and feel better every day. Every subscription represents a real person making a real change in their life, and we take that seriously.
With 500+ people across hubs in Cyprus, Ukraine, Poland, Spain, and the UK, we combine the scale of a market leader and the drive of a team that's just getting started.
The Product Engineer Mindset
We don’t hire people to implement specs. We hire people who can spot the right problem to solve, talk directly to product, design, data, and users to sharpen it, and ship the thinnest version that proves the bet, then iterate. If this is you, you probably:
- Measure your work in outcomes, not output. A feature isn’t done when it merges; it’s done when the metric moves, or you’ve learned it won’t, and killed it.
- Go to the source. You don’t wait for a perfect PRD. You sit with PMs, designers, marketers, and data, and sometimes users directly, to understand what’s actually being asked.
- Own things end-to-end. From the first conversation about a problem through architecture, code, rollout, monitoring, and the follow-up experiment. You don’t hand work off at a boundary.
- Have a strong bias to ship. Prototypes, A/B tests, feature flags, kill switches. You’d rather get something in front of users this week than a perfect plan in two months.
- Treat AI as leverage, not a novelty. You use agentic workflows to compress the loop between idea and learning, for yourself and the team.
What You’ll Own
This is an ownership role, not a feature factory seat. You’ll be on the hook for outcomes across the stack, not just the code in your area:
- A cross-platform foundation, end to end. Mobile, web, BFF, and infrastructure layers, built and evolved with an AI-first, agentic development approach, and held to outcomes you helped define.
- Scalable foundations for health & fitness apps. React Native and modern web technologies, designed so product teams can ship and experiment faster without rederiving the basics each time.
- The discovery loop with stakeholders. Working directly with product, design, marketing, and data to translate business bets into running experiments, not just tickets in a backlog.
- AI-agentic workflows across the SDLC. You’ll continuously improve how the team uses AI to raise productivity, code quality, and delivery speed, and prove the impact.
- Shared platform capabilities. Internal tooling, CI/CD pipelines, and AI-assisted workflows that make every engineer at Welltech faster and the product better.
- Native mobile and media experiences. Video playback, streaming, and HLS, owned from native integration through user-perceived quality.
- Modular, reusable systems. Backend-driven UI, white-label capabilities, and the architectural choices that let one team’s work compound for the next.
- Reliable integrations. Between frontend clients, BFF services, and platform infrastructure, with you on the hook for the health of the seams.
- The engineering culture. Architecture discussions, code reviews or pairing when working on trunk based development workflows, documentation, and continuous improvement, leading by what you ship and how you ship it.
WHAT WE’RE LOOKING FOR
Key responsibilities:
- Build and evolve a cross-platform ecosystem covering mobile, web, BFF, and infrastructure layers using an AI-first, agentic development approach
- Design scalable foundations for health & fitness applications powered by React Native and modern web technologies
- Work directly with product, design, and marketing stakeholders to rapidly translate business needs into scalable technical solutions and experiments
- Develop and continuously improve AI-agentic workflows across the full development lifecycle to increase team productivity, code quality, and delivery speed
- Develop shared platform capabilities, internal tooling, CI/CD pipelines, and AI-assisted workflows that improve development speed and product quality
- Work on native mobile integrations and advanced media experiences, including video playback, streaming, and HLS-based solutions
- Contribute to modular architectures, reusable systems, backend-driven UI solutions, and white-label application capabilities
- Build reliable and scalable integrations between frontend clients, BFF services, and platform infrastructure
- Participate in architecture discussions, code reviews, documentation, and continuous improvement of engineering workflows
Required skills:
- Strong commercial experience with React Native and modern TypeScript-based application development
- Solid understanding of full-stack architecture including mobile, web, BFF, and cloud/infrastructure layers
- Experience building scalable cross-platform systems and shared application foundations
- Deep understanding of software architecture, modular systems, scalability, and performance optimization
- Experience working with CI/CD pipelines, automation tooling, and modern developer workflows
- Strong engineering mindset focused on maintainability, reliability, testability, and fast iteration
- Comfortable working in AI-assisted or agentic development environments and adopting new AI-driven workflows quickly
- Experience with backend-driven UI architectures
Nice to have:
- Experience building white-label mobile applications or multi-brand ecosystems
- Experience designing and implementing BFF (Backend for Frontend) services
- Hands-on backend development experience with TypeScript (Node.js)
- Experience building internal developer platforms, shared tooling, or scalable platform capabilities
- Familiarity with OWASP mobile security best practices
- Experience with engineering methodologies focused on rapid iteration and high developer productivity (Trunk Based Development, CI/CD mindset, TDD, BDD, XP, etc.)
- Strong experience with native mobile integrations and media/video playback technologies
- Hands-on experience with HLS streaming and native video player integrations on iOS and Android (AVPlayer, ExoPlayer, Chromecast, AirPlay)
