Marketing Systems Engineer

What we're building Mutiny is the self-improving AI infrastructure for GTM teams to execute faster and close more revenue. Our ambition is to do for revenue velocity what Cursor and Claude Code did for engineering velocity. With Mutiny, everyone in sales and marketing gets a bench of GTM athletes that handle any work across their revenue motion and learn from what's actually moved their deals. In April we re-launched the product as an agent-first platform. Anthropic showcased us as a leader in AI GTM. MRR is growing more than 70% month-over-month, with customers like Uber, Rippling, and Snowflake. We're backed by Sequoia, YC, and Insight, and we're building a generational company. The opportunity Most engineers spend their career making predictable systems faster. You'll spend yours making non-deterministic ones trustworthy. As a senior engineer on our AI product team, you'll architect the Campaign Builder and Agent experiences marketers and sellers open every day to go from idea to personalized assets in minutes. You'll partner directly with product, design, and the founders to define what an agent-first GTM platform should feel like, and your calls on architecture, evals, and guardrails compound across thousands of customer accounts. This role is in person in New York City, five days a week, and we ship weekly. What you'll own The core agent surfaces. Architect and ship the Campaign Builder and Agent experiences end-to-end. Frontend, backend, prompts, evals, the whole stack. Reliability on top of LLMs. Make non-deterministic models feel deterministic at the surface. Build the retries, fallbacks, and orchestration so the customer never sees the failure mode. Evals and guardrails. Define how we measure quality, catch regressions, and keep brand and tone consistent across thousands of customer accounts. Speed and feel. AI products live or die by latency and the loop between intent and output. You'll obsess over both, and use coding agents and agent networks to ship f

The opportunity The best CEOs don't scale alone. As Executive Assistant to our CEO, Jaleh, your job is to scale her time and energy across every Mutineer, customer, and investor she touches. This is the traditional EA role and then well past it: you'll manage the calendar, inbox, and travel, but you'll also spot trends, build the processes and communication systems that make her better at her job, and act as her voice when it counts. You'll run the physical and social heartbeat of the company too, from the office to the events that keep a fast-growing team connected. Do this well and you become the person Jaleh and the whole company can't imagine operating without. What you'll own Jaleh's time. Calendar, email, travel, expenses, and event coordination. Be the trusted partner who responds fast and resolves every internal request before it becomes a problem. The inbox, in her voice. Build playbooks for processing email on Jaleh's behalf and route only what truly needs her. This takes sharp judgment, strong writing, and a real feel for how she thinks and how the company works. The calendar as strategy. Work with Jaleh each quarter to shape a calendar that reflects her actual priorities. Help Mutineers show up with the right pre-reads and prep so every meeting earns its place. Playbooks and pr
