Our platform processes billions of API requests per month and supports applications with millions of concurrent users, while delivering highly reliable, low-latency services and a great developer experience.

We're looking for a Sales Development Representative dedicated to our AI Moderation product to join Stream on our mission of elevating the quality of apps for billions of users globally. You'll build the top of our pipeline and set the tone for how prospects first experience Stream.

This is a full-time role based in our Boulder office, three days a week in the office.

It's a fast way to learn technical sales and own real revenue impact early. You'll report directly to the GTM Lead for AI Moderation, working as part of a dedicated product team rather than a general sales pool, a fast way to learn technical sales in a high-demand category and own real revenue impact early.

You'll partner with our Account Executives on moderation outbound, and work with managers to test new outbound ideas. Day to day, you'll write outbound messaging that's worth reading, run sharp qualification on cold calls, and personalize your outreach rather than blasting templates.

Responsibilities:

• Identify, research, and qualify new business through targeted outbound prospecting
• Run strong discovery to understand a prospect's needs and connect them to Stream
• Book qualified meetings with ICP prospects across phone, email, LinkedIn, and creative outreach
• Work closely with AEs: join intro calls and make the handoff clean
• Hit your activity and pipeline goals by keeping the top of funnel healthy
• Keep CRM data accurate in Salesforce
• Know Stream's AI moderation product, value, ICP, and competitors well enough to speak to them naturally

You're motivated, curious, and comfortable with a "no" on the way to a "yes." You think about outbound strategically, you like running experiments, and a fast-changing environment suits you. You're a self-starter who wants to learn the fundamentals of technical sales and contribute to revenue from the start.

You have:

• 6+ months of SDR or outbound lead-gen experience at a tech company
• Cold calling and emailing skills you can point to results for
• Experience with CRMs and sales engagement tools
• Strong business sense and the ability to think on your feet
• Clear, persuasive written and verbal communication
• Resilience: you handle rejection and stay motivated
• Experience in a fast-paced, goal-oriented environment

Bonus points:

• Experience at a SaaS startup
• Exposure to API-driven or developer-focused products
• Exposure to Trust & Safety, content moderation, or risk/fraud

You're the first impression prospects get of Stream, and you influence how companies keep their platforms safe at scale. You sit at the start of the pipeline, so your work shows up directly in how Stream grows. You'll join a strong GTM team across EMEA, APAC, and the US and talk to recognizable brands. You'll learn fast from people who sell a genuinely technical product, and there's real room to grow into an AE or other GTM roles.

Stream blends a supportive, social culture with deeply technical, world-class talent. You'll work with global colleagues across 35+ countries and learn from experts who build infrastructure trusted by top apps worldwide. You'll grow fast. You'll be challenged. You'll make an impact from day one.

We're a Series B company with offices in Amsterdam, Boulder, Toronto, Skopje, and a team of around 135+ people from more than 35 countries.

We're backed by Felicis Ventures, GGV Capital, 01 Advisors, Techstars, and Arthur Ventures, with angels including Dick Costolo (ex-CEO of Twitter), Olivier Pomel (CEO of Datadog), Tom Preston-Werner (co-founder of GitHub), and Nicolas Dessaigne (co-founder of Algolia).

We'll be straight with you: a startup is more demanding than a large company. There's no fixed playbook, you'll own your results, and you'll sometimes pick up work outside your title. That's also what makes it a fast place to grow. If you want real ownership more than structure and a set path, you'll feel at home here.
