Senior AI Infrastructure Engineer

Role Description

The Senior AI Engineer will serve as a technical cornerstone of VideoAmp's AI Infrastructure team, driving the design and execution of agentic workflow systems that bridge VideoAmp's platform APIs and AI-powered customer experiences. This is a high-impact individual contributor role at the intersection of LLM infrastructure, API design, production reliability, and developer enablement.

You will architect and own production-critical systems serving live customers, operate in a rigorous evaluation-driven culture, and help VideoAmp safely scale its agentic platform to direct enterprise consumers.

What You'll Do

• Own multi-tenant tool layers. Design and implement multi-tenant isolation, rate limiting, and caller-attribution systems as direct enterprise customers use MCP tools.
• Extend A2A interfaces and experiences. Enable customer and internal agents to invoke other agents in support of new initiatives.
• Build and own durable agent runtimes, including long-running execution, task lifecycle management, and failure recovery.
• Lead evaluation-driven development. Design golden scenario suites, automated CI/CD evaluation pipelines, and regression detection across all workflows.
• Implement progressive discovery strategies for context, tools, agents, and skills, using deferred loading, search, categorization, and semantic filtering.
• Design the agent harness and orchestration loop, leveraging isolated context, shared memory, and multi-agent coordination.
• Drive new agentic capabilities from design to launch for customer experiences, owning production rollouts.
• Participate in on-call rotation for customer-facing production systems; contribute to incident response, postmortems, and reliability improvements.
• Partner with internal engineering teams to negotiate and promote API-first designs that serve both programmatic and agentic consumers.
• Contribute to multi-provider LLM abstraction layers, ensuring flexibility among LLM providers.
• Facilitate AI office hours and cross-team enablement, serving as the internal expert on LLM tooling, agentic patterns, and tool configuration for teams across VideoAmp engineering.
• Author, review, and drive clear technical requirements documentation for new solutions: design docs, architecture diagrams, and postmortems.

Qualifications

• 6+ years of software engineering experience, with 1+ years in AI/ML infrastructure, LLM platform engineering, or agentic system development.
• Strong Go (Golang) engineering skills; backend systems are Go-first. Proficiency in Python and SQL is also expected.
• Production API design and operations: strong background in resource-based API design and experience building or consuming developer-facing platform APIs at scale, including on-call and incident response.
• Multi-tenant system design: experience implementing rate limiting, caller attribution, tenant isolation, and external support surfaces for shared production APIs.
• Deep experience with LLM APIs such as Anthropic or OpenAI, including prompt engineering and tool use/function calling.
• Practical experience designing agent loops for production systems, including context and state management across turns, prefix caching for latency and cost, and coordinating multi-step task execution.
• Experience with MCP or equivalent tool-layer abstractions for exposing platform capabilities to AI agents, or for building agents that consume them.
• Familiarity with A2A protocols and long-running, durable workflows.
• Experience building automated test and evaluation suites for LLM-based systems, including golden scenarios, regression detection, and quality gates in CI/CD.
• Track record of working across engineering, product, and operations teams to drive alignment and rollout of shared infrastructure and capabilities.
• Ability to produce design documents, postmortems, and system diagrams that create shared understanding across technical and non-technical stakeholders.

Nice to Have

• AdTech or media measurement familiarity, including linear TV, OTT, CTV, and digital video.
• Open-weights model experience such as Llama or Mistral.
• Fine-tuning experience such as LoRA or PEFT.
• Familiarity with Rust.

Compensation & Benefits

• Base Salary: $150,000 to $180,000 (commensurate with experience)
• Equity: Equity participation included
• Time Off: Discretionary & flexible PTO + Spring, Summer & Winter company breaks
• Health: Inclusive and comprehensive medical, dental & vision
• Financial: 401(k) with matching · HSA & FSA
• Family: Paid Maternity & Parental Leave for all family additions
• Perks: Cell phone & wifi reimbursement · Commuter benefits

Our Values

• One VideoAmp: We win together. We operate as one team, prioritizing shared success over individual wins.
• Own the Outcome: Accountability + Empowerment. We take full responsibility for results, not just tasks.
• Raise the Bar: Quality · Trust · Excellence. We hold ourselves and each other to a high standard.
