Responsibilities
About the Team The Security and Information Technology team is missioned to run and operate security infrastructures, platforms and technologies, as well as to support cross-functional teams to protect our users, products and infrastructures. In this team you'll have a unique opportunity to have first-hand exposure to the strategy of the company in key security initiatives, especially in deploying and maintaining scalable and secure-by-design systems and solutions.
Our challenges are not your regular day-to-day technical problems; you'll be part of a team that's developing new solutions to new challenges of a kind not previously addressed by big tech. It's working fast, at scale, and we're making a difference.
You are an Engineer first, and an AI-builder second. While your output will be autonomous AI agents, the day-to-day responsibilities include building the robust, scalable, and secure distributed systems that allow those agents to operate. This role will join a "Tiger Team". You will own the full vertical—from the React frontend where humans supervise agents, to the Python/Go backend services that power them, down to the Kubernetes infrastructure they run on.
ResponsibilitiesTo succeed in this role, you are expected demonstrate mastery of the following engineering fundamentals:
- Language Proficiency:
Expert-level fluency in Python (FastAPI, Django, or Flask) is mandatory for AI orchestration. - API Design:
Extensive experience designing RESTful APIs and GraphQL schemas. You understand idempotency, rate limiting, authentication (OAuth2/JWT), and API versioning strategies. - Distributed Systems:
Deep understanding of microservices architecture, message queues (Kafka, RabbitMQ, or SQS), and asynchronous task processing (Celery, Temporal). You know how to handle race conditions and ensure data consistency across services. - Database Design
- Relational:
Expert SQL skills (PostgreSQL/MySQL). You can design normalized schemas, optimize complex queries, and understand indexing strategies for performance. - No
SQL:
Familiarity with key-value stores (Redis for caching/session management) and document stores (MongoDB/DynamoDB) for flexible agent memory.
- Relational:
- Containerization:
You live in the terminal. Experience writing multi-stage Dockerfiles and managing container orchestration with Kubernetes (Helm charts, kubectl). - CI/CD Pipelines:
Experience setting up comprehensive CI/CD pipelines (Git Hub Actions, Git Lab CI) that include automated linting (flake8/black/ESLint), unit testing (PyTest/Jest), and integration testing before deployment. - Observability:
You build systems that are easy to debug. Experience integrating observability tools (Prometheus, Grafana, Datadog, Sentry) to trace requests and monitor system health.
While the skills above are the foundation, the following are the "force multipliers" highly preferred for this specific team:
Agentic Workflows- Vector Infrastructure:
Experience running vector databases (Pinecone, Weaviate, Milvus) in production, including hybrid search (keyword + semantic) strategies. - Agent Orchestration:
Practical experience with Lang Chain or Lang Graph to manage agent state, memory, and tool execution loops. - LLM Integration:
Deep familiarity with OpenAI/Anthropic APIs, specifically Function Calling (structured output) and context window management.
- Modern Frameworks:
Deep expertise in React (Type Script) ecosystems. You are comfortable using Next.js for server-side rendering and static site generation. - State Management:
Proficiency with complex state management libraries (Redux Toolkit, Zustand, or React Query) to handle real-time agent status updates without UI lag. - UI/UX Implementation:
Ability to implement responsive, accessible designs using modern styling systems (Tailwind CSS, Styled Components, or Material UI). You aren't just "patching" UIs; you build intuitive dashboards for non-technical operators.
Minimum Qualifications
- 5+ years of experience in software development with a strong focus on backend systems.
- Bachelor’s degree in Computer Science, Engineering, or a related field; OR equivalent practical experience (we value your Git Hub commit history more than your diploma).
- Proven proficiency in full stack web development using languages like Python and JavaScript for building robust, scalable applications.
- Demonstrated ability to work collaboratively and drive technical initiatives…
