Principal Engineer - Platform (m/f/d) at InPost

The Platform Principal Engineer is the senior-most individual contributor in the Platform Engineering Domain. You set the technical direction for how ~80 engineers build, operate, and evolve InPost's engineering platform — spanning cloud infrastructure, developer experience, reliability, and AI foundations. You operate at the intersection of architecture and delivery: you shape the strategy and you stay close enough to the work to validate it. This is not a consulting role. You drive technical decisions that stick. What You'll Do Technical Direction • Own the long-term technical roadmap for the Platform Engineering Domain across four pillars: Platform Engineering & Delivery, Developer Experience, SRE & Reliability, AI & Cloud Foundations. • Identify architectural risks and opportunities ahead of the teams — raise them early, propose solutions, drive resolution. • Define and evolve platform-wide standards: SDLC compliance (targeting SCS ≥ 80/100), observability baselines, cloud-native patterns.Cloud & Infrastructure • Lead the technical strategy for InPost's migration from on-prem data centres to GCP — targeting a 25–50% CO2e footprint shift from the Jan 2026 baseline by year-end. • Establish reference architectures for services running on GCP; review and govern deviations. • Drive cost efficiency, reliability, and security posture at the platform layer.Developer Experience • Define the developer platform vision: what self-service capabilities engineering teams get, how they get them, and what the experience benchmark is. • Partner with the Developer Experience and Platform Engineering leads to move from bespoke tooling to a coherent internal developer platform.AI Foundations • Shape the technical approach to AI adoption across InPost Technology (AES target: ≥ 75/100 by Dec 2026). • Design the infrastructure and platform primitives that make AI tooling safe, scalable, and measurable — not experimental. • Act as a technical bridge between the AI & Cloud Foundations team and the broader engineering org.Cross-Domain Technical Leadership • Represent Platform Engineering in architecture reviews, CTO-level discussions, and cross-domain technical governance. • Mentor senior and staff engineers; raise the technical floor across the domain. • Write well: your proposals, design documents, and postmortems set the quality standard.What You Won't Find Here • A governance-heavy role where influence is measured in slide decks. • A team that treats reliability as an afterthought. • A company that treats AI adoption as a comms exercise.
