Senior Front End Developer - React, TypeScript - FinTech

Excellent opportunity for an experienced Front End Developer with extensive React and TypeScript experience opens at a leading digital asset firm. The successful candidate will thrive on working with autonomy and to be heavily involved in innovative ideas for UX and Front End development., Core application development

• Design and build React applications using TypeScript for their internal and external user interfaces.
• Implement complex, stateful workflows tied to settlement cycles, approvals, statuses, and exception handling.
• Consume and integrate with Back End APIs that represent financial processes, not CRUD toys.
• Build components that prioritise clarity, auditability, and correctness.

Front End architecture and quality

• Own Front End application structure, state management, and data-fetching patterns.
• Establish and maintain sensible abstractions, avoiding over-engineering while preventing entropy.
• Write testable, maintainable code with clear separation of concerns.
• Ensure deterministic behaviour under partial failures, slow responses, or stale data.

UX in a regulated, operational context

• Translate complex domain concepts into interfaces that are unambiguous and hard to misuse.
• Design for professional users, not consumers. The goal is speed, accuracy, and confidence.
• Work with product and operations to refine flows based on real usage and operational risk, not guesswork.

Reliability, security, and correctness

• Handle edge cases deliberately: retries, timeouts, stale data, conflicting states.
• Ensure Front End behaviour aligns with Back End guarantees and regulatory expectations.
• Treat security as a baseline: authentication flows, authorisation boundaries, safe defaults.

Collaboration and ownership

• Work closely with Back End and platform engineers to influence API design and system behaviour.
• Take ownership of Front End decisions end-to-end: design, implementation, review, and maintenance.
• Contribute to engineering standards, code reviews, and technical discussions across the team.

• Strong commercial experience building React applications in TypeScript.
• Solid understanding of modern Front End architecture, including component design, state management, and data flow.
• Experience integrating front ends with non-trivial Back End systems and APIs.
• Ability to reason about edge cases, failure modes, and data consistency from the UI layer.
• Comfort working in a small, senior team with high ownership and minimal process theatre.
