Key Responsibilities
Technical Leadership & Architecture

• 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.

Stablecoin Protocol Development

• 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.
• Deliver secure, auditable operator workflows for:
• Multisig approvals / policy-controlled actions (approve/reject, quorum visibility, signer status)
• Real-time price feeds and reserves verification views and alerts
• Monitoring dashboards for on-chain and off-chain operations
• 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.

Payments & Settlement Infrastructure

• 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.
• Ensure strong audit trails and immutable logging UX for regulatory reporting, and collaborate with Legal/Compliance on VASP, MiCA, and Travel Rule implementations.
• Build "safety rails" into the product: circuit breakers, anomaly cues, and risk control workflows.

Compliance & Risk Management

• 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

System Integration & Operations

• 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.

Team Leadership & Collaboration

• Mentor engineers, set engineering standards, and raise the bar through reviews focused on security, performance, and maintainability.
• Partner tightly with Product, Operations, and Compliance; contribute to hiring and technical interviews; document architecture/runbooks/specs.

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.

Technical Skills

• Expert in Angular (TypeScript-first) for large-scale applications: architecture, performance, state management, complex forms, routing/guards, and building reusable UI systems.
• Perfect/Expert knowledge: able to design, implement, and review production React codebases (modern hooks patterns, performance, component architecture) even if Angular is the primary stack.
• Expert-level proficiency in backend development (or ) - must)
• Experience with blockchain integrations and transaction types; ability to contribute across services that power the frontend workflows.
• Strong foundations in cryptography concepts, key management approaches (HSM/MPC), and wallet infrastructure (sufficient to build safe UI + service flows).
• Event-driven/distributed systems mindset; strong SQL + NoSQL skills; familiarity with Docker/Kubernetes and CI/CD.

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.

Stablecoin & Blockchain Expertise

• 10+ years of software engineering experience, including 2+ years working directly with stablecoins/blockchain.
• Deep understanding of stablecoin models (fiat-collateralized, crypto-collateralized, algorithmic).
• Hands-on experience integrating with blockchain/stablecoin infrastructure providers (e.g., Infura, Alchemy, Fireblocks, or similar).
• Strong knowledge of EVM chains (Ethereum, Polygon, Arbitrum, Optimism, Base) and familiarity with at least one alternative L1 (e.g., Stellar/Solana/Algorand).

Payments & Financial Systems

• 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
• Understanding of FX markets, liquidity management, and market-making fundamentals

Security & Best Practices

• 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

Leadership & Communication

• Ability to execute technical initiatives and influence architectural decisions
• Strong communication skills, capable of explaining complex technical concepts
• Experience working in fast-paced startup or fintech environments
• Track record of mentoring engineers and elevating team capabilities
• Comfortable with ambiguity and ability to make pragmatic trade-offs
