Your primary playground is PHP/Laravel on the backend, with a meaningful share of work in a Java/Spring Boot service that owns parts of their payment domain. You’re also comfortable navigating a TypeScript/React frontend codebase and contributing to it when needed.

Beyond the code, they are looking for someone who genuinely enjoys thinking about architecture – someone who forms opinions, defends them with data, and changes their mind when shown a better path. They want a builder who is naturally drawn to new technologies and sees AI-assisted development not as a gimmick, but as a real productivity multiplier.

Responsibilities:

• Develop and maintain backend and frontend services for the Payment team using Laravel, Spring Boot, and TypeScript
• Design, document, and defend architectural decisions for new features and refactors, in collaboration with the other developers of the team

• Solid TypeScript skills and hands-on experience – you can read, write, and review frontend code confidently
• Strong SQL knowledge: you write queries, understand indexes, and can reason about query performance
• Proven ability to articulate and justify architectural decisions: weighing trade-offs around scalability, maintainability, and explaining the reasoning clearly to peers and stakeholders
• Fluency with REST API design and experience consuming or building JSON integrations
• Comfortable working in Git-based workflows with pull requests, branches, and CI gates
• Active user of AI development tools (Claude Code, Cursor, Copilot, or similar) – you’ve integrated these into your daily workflow and are curious about pushing them further
• A track record of working in Agile environments with cross-functional teams
• Upper-intermediate to advanced English proficiency

Nice to have:

• Experience with React and/or Next.js
• Prior exposure to payment systems (PSP integrations, 3DS, refunds, reconciliation) or other regulated/financial domains
• Knowledge of cloud infrastructure (AWS) and containerization (Docker)
• Familiarity with Keycloak (OIDC/OAuth2, B2B/B2C realm configuration, identity providers)
• Exposure to Domain-Driven Design (DDD) or hexagonal/clean architecture patterns
• Experience with state management libraries (Mobx, Redux, Zustand, etc.)

You are the right fit if:

• You get genuinely curious about new tools, patterns, and frameworks – and you act on that curiosity
• You see AI-assisted development as a craft to develop, not just a shortcut to reach for
• You take ownership of problems rather than waiting to be told what to do next
• You bring care and rigor to a domain where mistakes are visible to users and have financial consequences
• You’re direct in technical discussions and comfortable with disagreement as part of good engineering

• Perfect office location in the city-center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups

We run two companies in the online trading space — a prop firm and a brokerage. We're hiring our first dedicated backend/full-stack engineer to own the back-end end-to-end, starting with a real-time risk-monitoring & fraud-detection platform.

 ▎ What you'll build:
 - Integrations with trading-platform Manager APIs (cTrader, MetaTrader 5) over long-lived TLS/binary socket connections auto-reconnect, heartbeats).
 - Data pipelines: ingest live account/trading events → enrich (IP geolocation, VPN/proxy detection) → run detection logic (multi-accounting, impossible travel, shared IPs) → store in PostgreSQL/Supabase.
 - Secure REST APIs + live-updating dashboards for our risk team.
 - Deployment & operations: CI/CD, monitoring, alerting, backups (Fly.io / Railway / Vercel-style stack).
 

We have polished front-ends and clear specs already — we need someone to wire them to live data and ship to production. High ownership,direct access to founders, fast decisions.

▎Must-have: 3+ yrs production backend/full-stack · strong Node.js/TypeScript · solid PostgreSQL · real-time data (WebSockets / persistent sockets) · production deployment & ops · good written English.

 ▎ Nice-to-have: protobuf / TCP-TLS socket clients · MT5/cTrader or brokerage APIs · Supabase · React · fraud/risk/anti-abuse tooling  GDPR awareness.
 
 ▎ Process: intro call → technical chat → small paid trial project → offer.
