About the Role
We are seeking a Senior Frontend Engineer to join a domain-focused product team within a large financial services client. You will operate within a mature micro frontend ecosystem where architectural complexity is abstracted away by robust tooling. This allows you to focus your day-to-day efforts on delivering well-tested, resilient features that integrate seamlessly against GraphQL and REST APIs.
As a Senior individual contributor, you will own your user stories from conception to failure modes. While you will not be designing the platform itself, you are expected to push back with evidence when a story introduces fragility, leaky abstractions, or untested edges. You will work inside a single workspace with one CLI, one bundler, and one runner, respecting the platform's boundaries without needing to know its internal mechanics on day one.
The Environment
The client operates an SSR-first micro frontend architecture. Modules are independently deployable, isolated at runtime, and composed at request time. You will be expected to demonstrate fullstack awareness, understanding why issues like N+1 problems in GraphQL resolvers are frontend concerns, and possessing the ability to read schemas to infer upstream query costs. You will collaborate closely with backend engineers on contract design, navigating HTTP semantics, auth boundaries, and idempotency.
