Looking for a Senior who owns features end to end and picks up new things fast. Java is the main skill, Vue.JS & Angular are the second.

What the work looks like:

• Features end to end: DB migration, backend endpoint, and the frontend.
• Lots of API integrations with external providers (payments, verification, KYC). Needs to be done reliably — retries, idempotency, webhooks.
• Money logic and KYC.
• Take part in architecture decisions, not just implement them.
• Pick up new tech and problem domains fast — the stack and requirements will keep changing.

Stack:

• Backend (main): Java 21, Spring Boot 4, Spring Security, JPA/Hibernate, Flyway, PostgreSQL.
• Frontend (secondary): Vue.JS 3, Angular, Vite, zod, tailwind, shadcn.
• Infra: Docker, Jenkins.

Requirements — Backend:

• Strong Java/Spring: JPA/Hibernate, transactions, Spring Security.
• Concurrency: threads, race conditions, synchronization, distributed locks, ShedLock.
• Solid with the Java library ecosystem (Guava etc.) and knows when to use what.

Requirements — Frontend:

• Strong TypeScript and modern frontend development with Vue 3 and Angular.
• Vue 3: Composition API, composables, reactive state, component composition.
• Angular: standalone components, Signals, dependency injection, component composition.
• Data fetching and server state.
• Forms with VeeValidate + Zod.
• Client-side state management with Pinia and Signals.
• Routing with Vue Router and Angular Router.
• Comfortable with Tailwind CSS and component libraries, building responsive and accessible UI from designs.
• Working in a Vite + Turborepo monorepo.

Requirements — Common:

• Fintech experience (payments, accounts, money flows). This matters, not a nice-to-have.
• Multiple API integrations with external services: auth, retries, idempotency, webhooks.
• Real understanding of networking: TCP/UDP and how they actually work.
• Data formats and protocols: JSON, Protobuf, HTTP, gRPC.
• AWS and Git/GitHub.
• English B1+.

Nice to have:

• KYC providers (Sumsub, Onfido or similar).
• Crypto experience (blockchain, wallets, on-chain payments, stablecoins).
• Terraform, ECS/IAM/RDS in production.
• Comfortable using AI tools.

We Offer:

• 100% remote work.
• Competitive salary.
• Paid vacation and sick leave.
• Friendly and innovative work community.
