Lead Software Engineer (API) (m/k)

Nasze wymagania: Strong experience designing scalable API platforms on AWS (API Gateway, Lambda, ECS/Fargate, ALB, Cognito, EventBridge, IAM). Deep knowledge of contract-first API design, versioning, and schema governance. Expertise in authentication and authorisation (OAuth2/OIDC, JWT, SigV4). Hands-on experience with Terraform and infrastructure-as-code. Solid understanding of CI/CD, DevOps, security automation, and dependency management. Experience with event-driven architectures and observability tooling. Proven ability to define platform-wide standards and lead large-scale architectural change. Experience creating opinionated templates and enablement tooling. Strong stakeholder communication and ability to influence across teams. Hands-on builder with a pragmatic approach. Strong focus on security, automation, and API quality. Comfortable modernising legacy systems while designing for scale. O projekcie: We are building a next-generation Network-as-a-Service (NaaS) platform, transforming traditional network solutions into scalable, cloud-native services. The project focuses on redesigning and standardizing APIs to enable seamless integration, automation, and faster product delivery. A key part of the work involves defining API contracts, governance, and data models to support a consistent and reliable platform experience. The system operates in a distributed, event-driven environment with high requirements for performance, scalability, and reliability. This is an opportunity to shape the technical foundations of a modern, API-first platform used across global enterprise environments. Zakres obowiązków: Own and evolve the target API architecture across domains using AWS-native services. Define contract-first API standards (OpenAPI/GraphQL), versioning, schema governance, and CI/CD quality gates. Design and govern API Gateway patterns, routing models, Terraform modules, and policy-as-code guardrails. Architect identity and security models, including OAuth2/OIDC, JWT, AWS SigV4, rate limiting, and WAF controls. Enable teams through paved-road service templates (.NET, Python, TypeScript) with built-in auth, observability, and pipelines. Define integration patterns for event-driven and synchronous APIs, ensuring reliability and backward compatibility. Establish observability and reliability standards (logs, metrics, tracing, SLOs). Lead API modernisation, reducing technical debt and aligning legacy APIs with new standards. Partner with engineering, product, security, and SRE teams to drive adoption and best practices. Oferujemy: International, collaborative work environment. Exposure to large-scale cloud and integration platforms. Strong learning and development support. Competitive compensation and benefits. Hybrid work.
