About the role

๐Ÿš€ Senior ML Engineer (Systems) | AI Agents & Distributed Systems

Location: Sunnyvale, CA โ€” On-site

Employment Type: Full-time

Experience: 5+ years

Compensation: $150Kโ€“$230K + up to 1% equity

Visa: H-1B transfers, new H-1B applications & TN visas supported

Weโ€™re hiring a Senior ML Engineer (Systems) to join an early-stage AI company building infrastructure for the next generation of multi-agent enterprise workflows.

This is a highly hands-on role for an engineer who can bridge ML systems research, agentic AI, distributed infrastructure, full-stack development, and product engineering.

Youโ€™ll work closely with the CEO and Chief Architect to turn research-grade ML systems ideas into products that developers and enterprise customers genuinely enjoy using.

๐Ÿ”ฅ What Youโ€™ll Do

Build and productionize multi-agentic AI systems

Design scalable agent orchestration and infrastructure

Develop full-stack applications primarily using Python

Work with agent frameworks such as LangGraph, LangChain, AutoGen, CrewAI, Semantic Kernel, Google ADK, or equivalent

Deploy and optimize model-serving infrastructure using technologies such as vLLM, SGLang, Ray, NVIDIA Triton, or NVIDIA Dynamo

Build systems involving APIs, distributed systems, asynchronous jobs, queues, containers, deployment platforms, and cloud infrastructure

Develop intuitive developer-facing products around complex ML infrastructure

Create visualizations and product experiences using tools such as Tableau and Grafana

Work extensively with open-source software, with opportunities to contribute upstream

Translate research-grade concepts into documentation, examples, onboarding experiences, and product language

Collaborate directly with technical leadership in an ambiguous, fast-moving startup environment

Help shape architecture, engineering practices, and the product itself

๐Ÿง  Ideal Candidate

Youโ€™ll be a strong fit if you have:

(academic years can substitute if PhD from top institution in relevant ML systems field)

5+ years of professional software engineering experience

5+ years of ML systems engineering experience in production

Strong experience building multi-agent systems

Experience deploying multi-agent systems into live production environments

Strong understanding of agent scaling, distributed systems, or AI infrastructure

Hands-on experience with one or more agent frameworks:

LangGraph, LangChain, AutoGen, CrewAI, Semantic Kernel, Google ADK, or custom agent frameworks

Experience with model-serving platforms such as vLLM, SGLang, Ray, NVIDIA Triton, or NVIDIA Dynamo

Strong full-stack engineering capabilities

Experience with containers, cloud infrastructure, deployment systems, APIs, async jobs, queues, and distributed systems

Experience developing with open-source software

Strong product instincts and the ability to make sophisticated backend capabilities understandable and useful to developers

Excellent written communication skills

Ability to operate independently in an early-stage, ambiguous, rapidly changing environment

โญ Strong Plus

Candidates with any of the following will stand out:

Experience as a Solutions Architect

Experience as a Forward Deployed Engineer

Contributions to open-source projects

Experience working at an AI agent development company or inference provider

Experience building products sold to enterprise CTO/CIO buyers

Experience with products combining an open-source core + managed cloud/service layer

Experience scaling AI compute or agent orchestration systems

Experience in startup or high-growth technical environments

PhD or MS in ML Systems / Computer Science / a closely related field from a strong program

๐Ÿšซ This Role Is NOT a Good Fit If You Are:

Primarily from a traditional enterprise/non-technical background

Focused only on the application layer without systems, scaling, or infrastructure experience

Looking for a role where you are primarily managing rather than coding and building hands-on

Too far removed from day-to-day technical implementation

๐ŸŽ“ Education / Experience Flexibility

Professional experience is highly valued. A PhD or MS from a top institution in a relevant ML systems field may substitute for some professional experience.

๐Ÿ“ Work Arrangement

On-site in Sunnyvale, California, with limited flexibility considered on a case-by-case basis.

๐Ÿ’ฐ Compensation & Benefits

Base Salary: $150,000โ€“$230,000

Equity: Up to 1%

Position: Full-time

Hiring: 1โ€“2 engineers

๐Ÿ›‚ Visa Support

The company is open to:

H-1B transfers

New H-1B applications

TN visas

OPT / eligible visa transfers

๐ŸŒŸ Why This Opportunity?

This is an opportunity to work at the intersection of agentic AI, ML infrastructure, distributed systems, and enterprise software at an early-stage company.

You wonโ€™t simply maintain an existing platformโ€”youโ€™ll help design, build, scale, and productize the systems that power the next generation of enterprise AI workflows.

If youโ€™re an engineer who enjoys going deep technically, working directly with technical leadership, solving ambiguous systems problems, and turning cutting-edge AI research into production software, weโ€™d love to hear from you.
