Ability to use AI as part of the engineering workflow while maintaining ownership over architecture, code quality, testing, and technical decisions.
Experience building complex product interfaces involving
forms, tables, filters, dashboards, and multi‐step workflows
.
Strong understanding of modern frontend development practices and component‐driven architectures.
Experience with modern bundlers such as
Webpack, Rspack, or Vite
.
Experience with
Tailwind CSS
or similar modern styling frameworks.
Experience consuming
REST APIs
and working with
OpenAPI‐based services
.
Ability to debug and troubleshoot issues across frontend and backend boundaries.
Experience with modern state management and server‐state patterns such as
TanStack Query, React Context, and hooks
.
Strong debugging, problem‐solving, and technical decision‐making skills.
Ability to collaborate effectively with
Product, Engineering, and operational stakeholders
.
Advanced English proficiency, both spoken and written.
Nice to Have
Experience designing or integrating
AI‐agent workflows, AI‐powered interfaces, or automated support operations
.
Experience with
micro‐frontends
or
Module Federation
.
Experience working with
monorepos
using pnpm, Turbo, Nx, or similar tools.
Familiarity with
Refine, react‐intl
, or admin/operations‐focused internal platforms.
Experience developing
BFF layers with Node.js / Fastify
.
Experience with
Python / FastAPI
, particularly the ability to understand APIs, propose schema changes, or implement small backend endpoints.
Experience working with
PostgreSQL‐backed services
and transactional or domain‐oriented APIs.
Experience in
FinTech, payments, remittances, customer support platforms, or high‐volume operational systems
.
Experience with
GCP
, including technologies such as OIDC or Pub/Sub.
