Description

InPost Pay is building its fintech platform from the ground up and is looking for a Staff Engineer to define the technical direction for a frontend platform area. You’ll own long-term frontend technology decisions, create and maintain frontend architecture and standards (including micro-frontends, design-system boundaries, performance and accessibility), and act as the technical throughline between engineering teams and product strategy. You’ll also evolve an agentic, data-driven development harness for frontend workflows.

Responsibilities

• Define and maintain frontend architecture across the area: component architecture, design-system boundaries, micro-frontend patterns, client-side state management, and performance budgets across multiple teams
• Author Architecture Decision Records (ADRs) and RFCs with clear trade-offs and reasoning
• Evaluate and decide on key frontend technology trade-offs (framework/library, build tooling, SSR/CSR/ISR rendering, accessibility)
• Evolve the agentic development harness for frontend workflows with instrumentation, adoption measurement, and iteration
• Drive org-wide technical change by identifying frontend patterns and design-system components to adopt or deprecate broadly
• Provide technical input into product strategy and mentor Staff-track engineers through design reviews, pairing, and technical writing feedback

Benefits

• Work in a diverse, international, cross-functional environment with leading experts
• Work and learn from a senior leader and leadership team; expanded exposure across e-commerce and logistics
• Flexible hours and an excellent working environment
• Training opportunities for professional development
• B2B type of contract
