Zakres obowiązków

• Own the end-to-end architecture of an assigned system or customer journey step — maintain a current-state assessment, a target architecture, and a sequenced, costed roadmap between them.
• Produce and keep current all architectural documentation for the slice: C4 models (L1/L2), Architecture Decision Records (ADRs), ERDs, and sequence diagrams.
• Sit on the Architecture Board as the named decision authority for the slice — assess incoming proposals, drive decisions proactively, surface cross-slice conflicts, and escalate choices with material cost or strategic impact.
• Lead vendor and technology evaluations; validate team proposals against the target architecture; recommend or block technology choices within the slice with documented rationale.
• Treat AI as a default design ingredient — evaluate where AI patterns create leverage, drive their adoption, and maintain a clear inventory of AI components and their risk profiles. Ensure AI usage converges on sanctioned patterns and guardrails.
• Engage directly with product, commercial, and operations stakeholders to discover business intent before design begins. Translate business problems into technical requirements and trade-off frames — design for outcomes, not for tickets.
• Own and enforce engineering standards within the slice; serve as named DRI for at least one standard across the guild. Contribute reusable patterns and golden paths back to the wider engineering organization.
• Define SLIs and SLOs for the slice, review breach trends, and partner with Engineering Managers on quarterly reliability improvement goals.
• Coordinate with adjacent Architects to eliminate seams, duplication, and integration debt across slices.
• Actively teach architectural patterns, engineering standards, and AI guidelines across the organization — and measure adoption, not just publication.
• Provide technology and design input to Engineering Managers and teams on architecture decisions, integration patterns, and major refactors.

Wymagania

• 8+ years of hands-on software engineering experience, with at least 3 years in an architecture or principal engineering role spanning multiple teams or systems.
• Hands-on experience evolving legacy software at scale, from refactoring and performance optimization to leading phased re-architecture toward modern, maintainable platforms.
• Proven track record of owning end-to-end architecture for cross-cutting or platform domains — infrastructure, observability, developer platforms, shared services, or similar.
• Deep experience designing and evolving distributed systems at scale: service boundaries, integration patterns, event-driven architectures, and API design.
• Ability to produce and maintain living architectural documentation — C4 models, ADRs, ERDs, sequence diagrams — and hold others to the same standard.
• Experience defining and enforcing engineering standards across multiple teams, with measurable adoption outcomes rather than just published guidelines.
• Demonstrable ability to engage non-technical stakeholders — product, commercial, operations — and translate business intent into concrete technical requirements and trade-offs.
• Strong communication and influencing skills: able to drive architectural decisions through persuasion and documented rationale, without direct line authority over engineers.
• Comfort operating in a governed, multi-team environment — experienced with Architecture Boards, decision escalation paths, and structured ADR practices.
• Familiarity with modern frontend architecture patterns, including React, SSR, Next.js, and Backend for Frontend (BFF), sufficient to assess design decisions and engage credibly with frontend teams.

Nice to have:

• Experience working within or adapting scaled agile frameworks (SAFe, LeSS, or similar) in a principal engineering or architect capacity.
• Hands-on experience designing or productionising AI/ML systems — LLM integrations, RAG pipelines, agentic workflows, or model evaluation frameworks.
• Familiarity with travel, e-commerce, or marketplace platform architectures — particularly search, booking, or payments domains.
• Experience building or operating internal developer platforms, golden paths, or shared engineering toolchains adopted across a large engineering organisation.
• Background contributing to or maintaining a technology radar, vendor evaluation frameworks, or organisation-wide engineering standards programmes.
• Experience defining and operationalising SLOs at the platform level, including instrumentation, alerting, and reliability review cadences.
