Senior Machine Learning Engineer

AgentPlatform - Adobe Experience Platform

THE OPPORTUNITY

Build the Agent Platform That Powers Enterprise AI

Adobe Experience Platform powers personalized experiences for the world's largest brands.Our AI team is building a production-grade platform for autonomous AI agents - not a wrapper around an LLM API, but a full agent runtime with sub-second orchestration, tool and skill layers spanning thousands of endpoints, long-term memory, sandboxed execution, and a multi-tenant Agent-Ops stack, all runtime-swappable acrossproviders.

We're hiring Senior ML Engineers to own major components end-to-end. You'll work at the intersection of applied ML and systems engineering, and your decisions will shape a system that serves Fortune 500 marketing teams.

Multiple roles, one team:The team is growing fast to match the scale of whatwe'rebuilding -we'reactively hiring multiple Senior ML Engineers across the focus areas described below.We'llmatch your strengths to the right domain during the interview process.

WHAT YOU'LL DO

Your Impact

You'llspend most of your time building platform infrastructure, with regular exposure to customer needs that shapes what you build.

• Build core agent infrastructure.Own major components of the platform - the agent runtime, tool execution layer, memory systems, sandboxed execution, or control plane - and ship production-ready code against real constraints: sub-second orchestration latency, cost-aware model routing, and high-throughput inference pipelines.

• Design ML workflows at enterprise scale.Build the systems for model customization, serving, and lifecycle management that let the platform adapt to diverse customer workloads.

• Innovate,don'tjust build.You'llhave room to explore newapproaches toagent reasoning, tool orchestration, memory, or evaluation - and carry the best ideas from experiment to production. We value engineers who push the platform forward with original thinking, not just execute on a spec.

• Close the loop with customers.Join regular customerengagements to see how your systems perform in real deployments, then feed those insights back into the platform roadmap. This isn't a customer-facing role, but your work is directly shaped by the people who use it.

• Own what you ship.Architecture through production operations - deployment, monitoring, observability, and incident response. No throwing code over the wall.

Example Focus Areas

Most engineers go deep in one or two areas while collaborating across the broader platform:

• Agent runtime and orchestration

• Tool execution infrastructure

• Retrieval, memory, and context systems

• Evaluation, observability, and agent quality

• Sandboxed execution and security

• Fine-tuning, serving, and model lifecycle infrastructure

WHAT YOU BRING

Core Requirements

• Ph.D. or M.S. in Computer Science or related fieldrequired.

• 5+ years of experience building and deploying production ML systems, withdemonstratedwork on models and AI-powered applications that serve real users at scale.

• Strong software engineering fundamentals:proficiencyin Python and/or Java, experience designing APIs and microservices, and comfort owning production systems end-to-end (deployment, monitoring, incident response).

• Deep hands-on experience with at least one modern deep learning framework (PyTorch, TensorFlow, JAX).

• Production experience with LLMs: prompt/context engineering, working with LLM APIs, fine-tuning, or building LLM-powered applications.

• Experience with cloud platforms (AWS or Azure) and data infrastructure (Postgres, Redis, Elasticsearch, Snowflake, or similar).

• Self-motivated with strong communication skills and the ability to influence technical decisions in a collaborative, multi-functional environment.

What Sets You Apart

Youdon'tneed all of these - depth in one or two is what matters.We'llmatch you to the domain where your experience has the most impact.

• Agent or LLM infrastructure depth.You'vebuilt agent loops, tool-use orchestration, RAG pipelines, long-term memory systems, or fine-tuning/serving infrastructure - not as a prototype, but in production systems handling real traffic.

• Platform-scalesystemsthinking.You'vedesigned catalog systems, plugin architectures, or intent routing that work across hundreds or thousands of endpoints, andyou'vedealt with the messy reality of overlap resolution, versioning, and cost-aware routing at that scale.

• ML-Ops or Agent-Ops experience.You'vebuilt eval frameworks, execution tracing, drift detection, guardrails, or HITL intervention systems - the operational backbone that makes autonomous AI trustworthy in production.
  Builder who innovates.Youdon'tjust implement -you'veprototyped novel approaches, run experiments, and improved systems in ways thatweren'ton the original roadmap. Publications or open-source contributions are a plus, not a requirement.

• Multiplier instincts.You'vementored engineers, shaped a team's technical roadmap, or built internal tools and practices that made the people around you more effective.
