Job Description:

We are looking for a passionate Senior Engineer who wants to join our growing team, helping us to transform and scale our payments platform. This role will involve ownership of the entire engineering lifecycle from concept to production and release, being involved primarily in backend development with contribution to the frontend as well. As a Senior team member you will have influence with technical direction, work collaboratively with stakeholders and drive high standards for code quality and performance. To help us drive success and achieve business goals you will be responsible for designing, building, deploying and maintaining new long-term features and services that are both scalable and reliable.

Job Responsibility:

  • Own the frontend architecture for a stablecoin platform supporting multiple currencies and blockchains, with a focus on scalability, reliability, and maintainability
  • Lead the technical strategy for custody, treasury management, and liquidity optimization experiences—turning complex workflows into clear, safe, fast UIs
  • Establish and enforce frontend security standards and best practices across development, deployment, and monitoring (especially for high-risk financial workflows)
  • Build UI foundations: shared component patterns, state management conventions, API contract standards, performance budgets, accessibility, and observability
  • Build and maintain end-to-end integrations surfaced through the product—stablecoin rails, blockchain infrastructure, and related APIs—with robust UX for failure modes and reconciliation
  • Participate in backend/smart-contract-adjacent work where needed (e.g., shaping flows for escrow/settlement), while keeping ownership of the customer/operator UI quality bar
  • Build frontend experiences for reconciliation and settlement across blockchain + banking rails, including transparency into statuses, exceptions, and recoveries
  • Create operator tooling for transaction routing, fee optimization, and continuity (failover/DR visibility and controls)
  • Implement compliance-facing workflows and admin consoles for transaction monitoring, screening, AML/CFT controls, sanctions screening, and address allow/deny lists
  • Integrate transaction monitoring, screening, and compliance controls for AML/CFT requirements
  • Collaborate with legal and compliance teams to implement VASP and MiCA requirements and travel rule protocols
  • Shape and implement APIs/webhooks (as a consumer and contributor) to ensure frontend needs are met cleanly and safely
  • Integrate with banking partners, liquidity providers, and DeFi protocols, providing robust UI/admin tooling for operational reality
  • Lead incident response, debugging, and post-mortems with strong production discipline

Requirements:

  • Prior fintech/regtech product exposure with understanding all the vocabulary, tooling, objects and user journeys and transaction flows together with understanding that UX correctness is as critical as system correctness
  • Expert in Angular (TypeScript-first) for large-scale applications: architecture, performance, state management, complex forms, routing/guards, and building reusable UI systems
  • React.js knowledge: able to design, implement, and review production React codebases (modern hooks patterns, performance, component architecture) even if Angular is the primary stack
  • Good proficiency in backend development (Nest.js (or Node.js) - must)
  • Experience with blockchain integrations and transaction types
  • ability to contribute across services that power the frontend workflows
  • Event-driven/distributed systems mindset
  • strong SQL + NoSQL skills
  • familiarity with Docker/Kubernetes and CI/CD
  • Understanding of payment systems architecture (clearing, settlement, and recs)
  • Knowledge of banking APIs, payment networks (SWIFT, ACH, SEPA, Faster Payments), and treasury operations
  • Experience with financial compliance requirements, KYC/AML processes, and transaction monitoring
  • Strong security mindset with experience in secure coding practices
  • Experience with security auditing processes and working with external audit firms
  • Knowledge of secure key generation, storage, and rotation practices
  • Candidates will need to have the right to work in the jurisdiction that they are looking to work in

Nice to have:

  • Experience building high-stakes operator tooling (approvals, permissions, audit logs, incident tooling)
  • Familiarity with real-time UI patterns (streaming updates, websockets) for trading/treasury/compliance dashboards
