Our mission is to transform complex AI and distributed systems into reliable, secure, and high-impact infrastructure that supports the daily work of public servants and decision-makers. We design solutions that operate in contexts where usability, reliability, security, and regulatory compliance are non-negotiable. You will join the team responsible for developing a multi-tenant agentic platform that combines structured LLM workflows, tool orchestration, and distributed execution. The goal is not experimentation — it is delivering production-grade systems capable of operating in demanding public and B2B environments. This role requires autonomy, technical ownership, and responsibility in architectural decision-making. You will play a key part in evolving the system from advanced architecture to resilient, scalable infrastructure — ensuring performance, security, confidentiality, and operational robustness at scale. We are entering a critical phase: scaling users while hardening the system for production-grade reliability. We are not looking for someone to execute tickets. We are looking for someone to help shape and elevate the system. What You’ll Do Strengthen the robustness and scalability of an event-driven, multi-tenant architecture Evolve a product intended to operate at meaningful scale across public and enterprise environments Design and implement new AI agent capabilities (planning logic, execution orchestration, tool control, reasoning flows) Improve idempotency, delivery guarantees, and failure handling over Redis Streams and consumer groups Define and enforce concurrency control, resource isolation, and tenant boundaries Improve lifecycle management of ephemeral Docker workers Design safe replay and recovery mechanisms in distributed workflows Ensure confidentiality, integrity, and secure handling of user data Contribute to architectural decisions balancing scalability, cost efficiency, and resilience Help evolve the platform from advanced architecture to battle-tested production system You will directly influence how the system behaves under real-world load, failure scenarios, and growth. What We’re Looking For Core Requirements 7+ years of backend engineering experience, including ownership of systems in production Proven experience evolving systems into stable, production-grade environments Real-world experience with distributed systems under load Strong understanding of: Concurrency and async programming Event-driven architectures Message brokers / streaming systems Idempotency and retry patterns Failure modes in distributed systems Experience with Docker and containerized execution Experience designing secure, multi-tenant systems Understanding of security best practices in distributed and multi-tenant systems AI & Engineering Mindset Comfortable using AI-assisted development tools (Copilot, Cursor, Claude, etc.) Experience integrating LLM APIs into production systems Interest in designing systems where AI components are part of the execution logic — not just UI features Pragmatic about balancing innovation with reliability Nice to Have Experience with Redis Streams Distributed tracing (OpenTelemetry or similar) Experience in regulated or public sector environments Cost-aware architecture design What We Value Engineers who have solved problems that don’t appear in tutorials Systems thinking and architectural awareness The ability to anticipate failure before it happens Pragmatism over hype Ownership and autonomy What We Offer Full-time employment contract High autonomy and direct architectural impact on product evolution and strategic technical decisions Clear opportunity for professional growth and career progression A collaborative environment with close proximity to product and strategic decisions Access to modern tooling and infrastructure, including state-of-the-art AI technologies Continuous learning and exposure to real-world challenges within Public Administration contexts Hybrid work model (remote + on-site presence in the Guimarães region) Start date: to be defined according to candidate availability Profit sharing and equity participation aligned with long-term commitment and contribution Join Whiteflow If you’re ready to take on a role with real technical depth, meaningful impact, and strong growth potential — we’d love to hear from you. This is an opportunity to work on complex AI-native infrastructure, contribute to systems that operate in demanding public sector environments, and help shape the evolution of a product with long-term strategic relevance. 🔗 Apply here: https://forms.gle/ESSWJWZp7ebpov5Z6
