What do we need We are seeking a Senior Full Stack Engineer with advanced Python skills to join our team building and advancing the Luma platform-an AI-Native Multimodal Research Platform for Scientific Intelligence. A platform that helps customers analyze and configure data within their system. This role offers the opportunity to work on cutting-edge AI/ML technology, architecting scalable microservices, and delivering production-ready systems that integrate with enterprise data platforms. You will build AI agents that perform real work-systems that plan tasks, call tools, execute workflows, interact with APIs, and integrate with real-world data sources. You'll be working in a collaborative, agentic coding environment where modern development tools support your workflow, enabling rapid iteration while maintaining high code quality standards.

In this role you will get to

Development & Implementation

• Design and implement AI agent workflows and tooling using LangChain/LangGraph, enabling AI models to plan actions, call tools, use APIs, search information, and reliably complete multi-step workflows.
• Build and maintain the tools, function interfaces, and system connectors that AI agents use to interact with databases, document stores, enterprise apps, and external APIs.
• Ensure AI agents operate safely, follow rules, respect permissions, and reliably execute within defined constraints.
• Lead and execute the design and implementation of core workflow orchestration and tooling features, including automated tasks and background processes.
• Build scalable FastAPI services with well-defined RESTful APIs and real-time streaming endpoints.
• Create modular, reusable service components with strong authentication, error handling, and pagination patterns.
• Develop and guide React frontend components for real-time interactions and data visualization.
• Implement multi-tenant architecture with secure isolation, resource boundaries, and long-term scalability.
• Provide technical guidance to other engineers during implementation, ensuring high-quality, maintainable solutions.
• Evaluate risk when implementing new features or refactoring, and propose safe rollout strategies.

Architecture & Design

• Clean Architecture principles with clear separation of concerns
• Microservices design patterns including service discovery, API gateways, and interservice communication
• Event-driven architecture with message queues and async processing
• Subprocess isolation patterns for credential management and security boundaries
• Influence architectural direction across teams, helping bring clarity and structure to ambiguous problems.
• Architect robust AI agent execution layers that ensure determinism, observability, and reliable stepwise execution.

Quality & Operations

• Write comprehensive automated tests using pytest and Jest, including integration and behaviour-driven tests.
• Implement structured logging, correlation IDs, and observability patterns to ensure system clarity and operability.
• Contribute to and improve CI/CD pipelines with automated testing, linting, and deployment workflows.
• Set up effective monitoring and alerting for production systems.
  Lead or support critical incident resolution with calm, context-driven decision-making.
• Drive platform-wide improvements in performance, reliability, and technical quality.
• Exercise independent judgment in methods, techniques, and evaluation criteria to ensure robust outcomes.
• Instrument AI agent systems with monitoring, tracing, and guardrails to ensure safe and predictable behaviour in production.

Collaboration & Documentation

• Document architectural decisions, engineering patterns, and approaches that become long-term references for the team.
• Provide approach summaries and technical proposals before major implementations to ensure alignment with product and engineering partners.
• Participate in planning and estimation, applying deep technical judgment and strong product awareness.
• Mentor engineers, raise team capabilities, and guide others through complex engineering workflows (feature branches, PRs, ticket management).
• Build relationships across engineering and product groups, influencing roadmaps and cross-team initiatives.
• Communicate risks, challenges, and opportunities proactively and clearly to stakeholders.
• Document and evangelize best practices for safe, reliable, and maintainable AI agent design.

We are looking for people who have 10+ years of professional software development experience, including significant experience owning and delivering large-scale technical systems. You should bring the ability to design durable architectures, independently lead high-impact engineering efforts, and mentor other engineers while maintaining exceptional coding standards. You should enjoy architecting clean, resilient services, solving complex systems problems, and shaping long-term technical direction for the areas you support.
