Their product helps users save time and money through automatic cashback and coupon discovery, plus features like price monitoring, sustainability signals, and flexible payment options. The company is now scaling internationally, with a major focus on an AI‑powered shopping assistant that understands user intent and recommends the best options based on clear criteria (price, quality, and impact). What we are looking for Production scale: you’ve run and improved high‑traffic systems (observability, incidents, scalability). DevOps mindset: you make shipping faster and safer (CI/CD, releases, automation, tooling). Cost + performance: you balance reliability, latency and cloud spend with clear impact. Security basics: IAM/permissions, secrets, least privilege, pragmatic hardening. Cloud native: strong AWS (serverless) or equivalent;IaC and modern deployment patterns a plus. Engineering first: strong design, testing, maintainability, and clean platform standards. Product‑aware: you care about UX, performance metrics and real usage at scale. Clear communicator: you influence through docs, reviews, and mentoring. What you’ll be doing As Platform Engineer, you’ll own platform end‑to‑end and turn scattered infra work into a clear platform that helps every engineer ship faster and safer. Infrastructure: improve scalability, resilience, capacity, and failure handling. Observability: build metrics/logs/tracing/SLOs and low‑noise alerting. Cost + performance: reduce major cost drivers while keeping reliability and latency tight. Developer experience: level up CI/CD, releases, environments, automation, and “golden paths”. Security baseline: strengthen IAM, secrets, hardening, and security monitoring without adding friction. Technical leadership: set the platform roadmap, align teams, and drive cross‑team execution.
