Senior / Staff Platform Engineer (AWS · Infrastructure · Distributed System)

Wymagania: - 6+ years building and running production infrastructure. - Deep AWS knowledge and strong operational instincts. - Infrastructure as Code only — no manual steps, no console dependency. - Strong distributed systems thinking: ordering, retries, idempotency, recovery. - Experience with PostgreSQL, Lambda, SQS, Redis, S3, and CI/CD. - Obsessed with reliability, security, visibility, and automation. - Comfortable owning critical infrastructure end to end. O firmie: - Blue is building the trust layer the AI economy has been waiting for — a protocol for structured, verifiable, multi-party agreements that execute deterministically, leave an audit trail, and work across any system. Think smart contracts, minus the blockchain overhead. - Our products are already being built and tested with real integrations: - • PayNotes — Programmable payments with conditional capture, milestone releases, refunds, vouchers, and partner settlement. - • MyOS — SaaS orchestration layer for merchants and agents. Cross-platform trust, without writing a line of Blue Language yourself. Zakres obowiązków: - Own all AWS infrastructure end-to-end — architecture, cost, security, reliability, and compliance. No infrastructure team above you. - Design and maintain CI/CD pipelines that let engineers ship confidently and fast — zero manual steps from commit to production - Build monitoring and alerting that surfaces real problems early: queue depth, processing failures, latency spikes, delivery anomalies — dashboards that tell you what’s actually wrong - Manage PostgreSQL at scale — configuration, connection pooling, migration strategy, performance, backup and restore - Keep real-time and async processing components healthy across Lambda, SQS, Redis, S3, and the services that connect them - Enforce IAM least-privilege across the system — service-to-service trust, secrets management, network isolation - Manage environments (dev / staging / prod) with infrastructure parity and clean promotion paths - Own cost visibility and optimization across a growing AWS footprint - Use modern AI tooling to accelerate infrastructure work and experimentation Oferujemy: - Competitive B2B compensation based on experience - Equity — own a piece of what you build - Fully remote work in an async-first environment - Direct collaboration with the founding team - High autonomy and fast decision-making - Small team, outsized impact - Work on technology that is genuinely novel - End-to-end ownership across product, systems, and production - Protocols don’t get built by committees. They get built by small teams who understood the problem before anyone else did
