Platform/DevOps Engineer — Remote, AI-Powered Infra

Lekta; Kraków; Hybrid; PLN 180,000 - 260,000; Full time

Job summary

Lekta is building the next generation of conversational AI platforms with a platform-focused Platform / DevOps Engineer who will own end-to-end infrastructure across public and private clouds. You will ensure sub-second latency, multi-tenant isolation, and deterministic compliance for enterprise clients.

We value hands-on, ownership-driven engineers who ship production work and collaborate closely with founders and leadership.

Qualifications

• Significant production experience running Kubernetes at meaningful scale.
• Multi-tenant SaaS architecture background, with isolation/pooling trade-offs.
• Hands-on experience operating across both public and private cloud environments.
• IaC fluency and configuration-level networking depth (ingress, mTLS, service mesh, DNS).
• Fluent in English (B2) and Polish (C1).

Responsibilities

• Design, run and evolve Lekta's multi-tenant production infrastructure on Kubernetes across public and private cloud environments.
• Own the infrastructure for real-time conversational channels, where latency is part of the product spec.
• Build the routing, fallback, and reliability layer for inference workloads across multiple model providers.
• Run cost engineering for the platform — per-tenant attribution, budgets, and optimization of inference and infrastructure spend.
• Establish observability that lets on-call engineers reason about agent behaviour, not just request timing.
• Own the CI/CD pipeline that protects production deploys, with quality and regression gates.
• Establish the compliance baseline for regulated enterprise customers — secrets, PII handling, audit trails.
