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 design hires inherit a system. You'll build it. As a founding designer, you'll partner with the founders and engineering to define how Mutiny looks, feels, and behaves, from the first interaction with the creative agent to the final published asset. They have high standards and strong opinions and you'll hear from them constantly. The patterns you set become the shared language for what AI-native GTM software feels like. This role is in person in New York City, five days a week. What you'll own The end-to-end product. From the first interaction with the creative agent to the final published asset. Design new surfaces, rethink existing ones, and figure out which tedious parts of GTM work AI should take over so customers spend their time being strategic. The creative agent's output. The work the agent produces matters as much as the surface around it. Partner with engineering on better defaults, smarter constraints, and stronger adherence to brand guidelines. An AI that's genuinely creative and knows how to color inside the lines when it needs to. Taste as a system. Curate what good looks like. Build the feedback loops that make the model's output sharper every week. Decide what ships and what doesn't. The design system. Components, patterns, and guardrails that let prod

The opportunity We're looking for a Head of GTM to bring Mutiny to millions of users. You'll sit shoulder-to-shoulder with the founders, own revenue end-to-end from first touch to retention, and help shape the decisions that define the company’s brand and culture. You’ll be building the AI infrastructure layer that reshapes how every GTM team operates. This role is in person in New York City, five days a week. What you'll own Revenue. PLG self-serve signups and conversion, sales-led motion including pipeline and ARR, retention and expansion. Marketing. Build the engine from zero to inevitable, including hiring the team and building the channels. GTM engineering. Build the agent-powered growth stack (including Mutiny!) that lets 5 people out-ship a team of 50. Sales and CX.

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

The opportunity Most CS roles are graded on how few problems the customer has. You'll be graded on how much they grow. As a growth strategist at Mutiny, you'll own a book of managed accounts and become the reason teams at customers like Rippling, Uber, and Snowflake get more out of AI than their peers. CS isn't a support function here. It's how we turn early traction into the customer base that defines a category. You'll build the playbooks as you go and shape what customer success looks like at an AI-native company from the ground up. This role is in person in New York City, five days a week. What you'll own Your book. Onboarding, adoption, retention, and expansion across your managed accounts. Every customer outcome runs through you. Customer expertise. Become the expert on how each customer's business works and where Mutiny fits in. Translate that into "aha" moments that move their roadmap. The AI motion. Teach customers how to use our agent-first platform to create assets that actually move the needle for their sales and marketing teams. Their team uses Mutiny because you made it obvious how.

As our AI strategist lead, you'll own Mutiny's managed account book and lead the technical solutions function that backs up our most complex customers. The teams running Mutiny (Rippling, Uber, Snowflake, Zendesk, and Gusto) are betting hard on AI, and they need post-sales partners who move their roadmap forward, not just their renewal date. You'll set the bar for what great support looks like, build the playbooks that let CS scale, and step into people management as we hire AI strategists underneath you.

The Opportunity Most brands hire creators to make content. We're hiring one to define how Mutiny shows up in the world. As our social media creator, you'll own the brand voice across every channel, build the AI workflows that let you move at the speed of culture, and place the bets other B2B brands are too scared to take. You'll partner with the founders to turn a fast-growing AI company into one people actually want to follow. What You'll Own The numbers. Brand awareness, impressions, and sign-ups from the social channels you own. The creative bar. Be the person whose work everyone secretly screenshots. Turn raw ideas from founders, product, and customers into content with a point of view so strong it travels on its own. Our social presence. Own how Mutiny shows up across LinkedIn, X, YouTube, and TikTok. Grow what's working, launch what isn't there yet. The AI workflow. Build agent pipelines that turn one podcast into a week of content. Train voice models so drafts sound like us. Run evals so the stack gets sharper every week. Brand campaigns. Read the room, read the data, then make the call. Place the swings other brands are too scared to take, and know exactly why they worked when they do. Product marketing media. Content that helps people understand what we do and how our product work

About Bolna Bolna is Voice AI infrastructure built for India - and now for the world. We help businesses deploy intelligent voice agents that can call, converse, and convert in any language, at scale. From collections to customer support to sales, our agents handle millions of conversations so humans don’t have to. We’re a YC F25 company, backed by General Catalyst, with 1,050+ paying customers and growing fast. Our team of ~25 is based in Bengaluru. The Role Every voice AI agent Bolna deploys makes real-time judgment calls - when to speak, when to go silent, when a customer is done talking, when to hand off. We’re building automated systems to grade these calls at scale, using LLMs as judges of call quality. But before you trust a model’s judgment, you verify it against a human’s. That’s this role. You’ll listen to real calls, annotate what actually happened, and check whether our automated systems - LLM-as-judge evals and quantitative signal detection - got it right. It’s precise, high-attention work, and it sits right at the center of how we know our voice agents are actually working. This is an internship role for someone early in their career who wants hands-on exposure to how a voice AI company builds trust in its own AI. What You’ll Do Annotation Listen to and annotate real customer calls - transcription review, issue tagging, labeling - using tools like Label Studio Follow (and help sharpen) annotation guidelines for a multilingual environment (Hindi, English, Hinglish, ) Verifying LLM-as-Judge Evaluations For calls flagged by our automated eval pipeline, verify whether the model’s call was actually correct - for example, confirming whether a detected barge-in (agent/customer talking over each other) genuinely happened by listening to the audio Mark agreements and disagreements clearly, with reasoning, so we can measure and improve model accuracy over time All tools needed for this will be provided Verifying Quantitative Measures Check system-flagged quantit
