Senior AI/ML Engineer

About the role: We’re looking for an experienced Backend engineer to help drive and evolve our product, focusing on high-impact innovation projects as part of our Linea AI team. You will be working on cutting-edge technology and ideas and bringing AI prototypes to production. You will work closely with Labs team to operationalize and scale AI prototypes across many customers.

What you’ll do:

• Design and scale distributed systems: Architect, build, and optimize highly scalable and fault-tolerant systems that process large graph datasets at enterprise scale, handling billions of events in real time from tens of thousands of endpoints with sub‑second latency.
• Solve complex scaling challenges: Tackle real-world performance and reliability problems through deep analysis, profiling, and systematic troubleshooting in high-throughput distributed environments.
• Build with modern infrastructure: Develop and evolve a microservices‑based architecture using technologies such as Go, Kubernetes, Docker, and Redis, in a continuously improving production stack.
• Engineer secure‑by‑design software: Write hardened, security‑first code capable of safely processing untrusted data, resisting real‑world attack vectors, and operating reliably across large‑scale, internet‑facing systems.
• Productionize AI systems: Partner with research and product teams to operationalize AI prototypes, turning experimental models into robust, scalable, and production‑ready services.

Who you are:

• Proven Backend Expertise: 6+ years of experience building and scaling backend systems, with strong proficiency in Python and/or Go, powering production applications used at scale.
• Full‑Stack Impact: Demonstrated track record of designing and delivering full‑stack applications that are actively used in real‑world, high‑traffic environments.
• Generative AI & ML at Scale: Hands‑on production experience with large‑scale foundational models and transformer‑based architectures, including deploying, monitoring, and iterating on GenAI systems.
• Agent & Workflow Systems: At least 1 year of experience building AI agents and orchestration workflows using frameworks such as LangChain, LangGraph, Genkit, or similar technologies.
• ML Systems & Data Pipelines: Experience delivering machine learning systems at scale, including robust model evaluation, continuous quality improvement pipelines, and data processing using columnar databases and large messaging systems (e.g., Pub/Sub, Kafka).
• Ownership & Innovation Mindset: Comfortable working in remote, fast‑paced environments, with an entrepreneurial mindset‑driven to solve complex, real‑world problems through innovation and breakthrough technology.

Good to have:

• Security & Product Domain Experience: Background building products in data security, DLP, or application security environments.
• Cloud Data & AI Workflows: Experience with GCS and BigQuery, and familiarity with LangGraph or similar frameworks for AI agent orchestration.
• LLM Evaluation & Quality Systems: Hands‑on experience designing or operating LLM evaluation pipelines, including automated testing, monitoring, and continuous quality improvement.
