Sobre a vaga
We're looking for a Senior AI Engineer to join one of our R&D teams building the AI-driven core of our product. The role involves building AI-driven features, applying judgment about the AI tooling landscape, and cloud-native architecture in Go. You will evaluate whether new tools or techniques are worth adopting and help the team decide what to build vs. buy vs. integrate.
O que vais fazer
- Design, build, and own LLM-powered pipelines and agent-based systems that find, triage, and remediate security risk in production, at scale
- Design retrieval and context strategies (RAG, tool use, memory) that ground model behavior in our product's data and domain
- Define and run evaluations for model/agent quality and use them to drive iteration and model selection
- Evaluate emerging AI tools, models, and frameworks against our product needs, producing clear build-vs-buy-vs-integrate recommendations for the team and leadership
- Stay ahead of the AI landscape: new LLM releases, agent architectures, orchestration frameworks, and techniques and translate relevant developments into concrete engineering proposals
- Own the reliability of AI features in production: guardrails, structured output validation, fallback behavior, and observability tuned for LLM-based systems
- Participate in design discussions and code reviews, bringing an AI-informed perspective to architecture decisions
O que é pedido
- 5+ years of professional software engineering experience, with strong hands-on experience building with LLMs and AI agents, not just experimenting with them
- Experience designing RAG pipelines, retrieval strategies, or context/memory systems for LLM applications
- Practical experience evaluating model and agent quality (accuracy, hallucination, latency, cost) and using evals to guide decisions
- A demonstrated habit of evaluating and comparing AI tools, models, or vendors, with informed opinions on tradeoffs
- Experience with cloud AI services (AWS Bedrock, Azure OpenAI, Vertex AI)
- Strong proficiency in Go and/or Python
- Solid understanding of distributed systems (message queues, gRPC/REST APIs, relational databases) and experience with Docker/Kubernetes
- Strong testing, CI/CD, and observability fundamentals
- Excellent English communication skills
Valorizado
- A genuine research habit, following AI research/practitioner communities
- Experience with vector databases and embedding models
- Application security knowledge
- GitOps tooling (ArgoCD, Helm), OpenTelemetry
O que é oferecido
- great work environment
- professional development
- challenging careers
- competitive compensation
- great work-life balance
- great benefits and perks throughout the year
