Sales Development Representative

We’re looking to hire a SDR who will own top-of-funnel via both manual and semi-automated outbound. In this strategic role, you’ll develop and execute high-velocity outreach plays, test and refine messaging, and ensure we secure access to key accounts—laying the foundation for our scalable GTM engine. About Antimetal Antimetal is building the future of infrastructure management . We're starting by creating a platform that investigates, resolves, and prevents issues—giving engineers their time back to focus on what they do best: building great products. What You’ll Do: Execute high-volume outbound: Send and manage large cadences of emails and calls, handling sequencing, throttling, suppressions, and bounce logic. Run A/B tests at scale : Rapidly design and iterate subject lines, messaging angles, and send times to optimize engagement. Develop account-based plays : Own a book of ~50 target accounts—researching personas, crafting tailored outreach, and adjusting segmentation based on response data. ● Full-stack deal origination: Source and qualify leads, book meetings, and support closing SMB deals with polished collateral (decks, one-pagers, talk-tracks). Collaborate with GTM Team : Feed manual workflows into automation pipelines; partner on tooling selection and integration. Optimize via metrics : Track SDR KPIs (volume, response rate, SQL conversion, meetings booked) and use insights to refine sequences and channel mix. What you bring: GTM pipeline development : Proven ability to launch end-to-end outbound workflows from rapid prototype to production, iterating on hypotheses with A/B tests and real-world feedback, and aligning plays against a defined set of key accounts. Stack strategy : Deep conceptual grasp of CRM, engagement, and orchestration primitives—skilled at evaluating trade-offs and stitching together best-fit systems with the GTM team to build and execute a pipeline that supports quota attainment. Outbound automation expertise : Track record designing and operating high-throughput outreach engines (tens of thousands of sends/day) with built-in deliverability controls (throttling, suppressions, retries) and driving engagement that feeds qualified leads into the closing motion. Resilient workflow design : Expert at mapping multi-stage GTM flows—from initial contact through demo to deal close—surfacing failure modes or bottlenecks, and embedding automated guardrails, alerting, and self-healing routines. Quota- and metrics-drive n: Skilled at defining and tracking KPIs (response rate, conversion, pipeline velocity, quota attainment), instrumenting real-time dashboards and alerts, and continuously tuning pipelines and close motions based on data. Deal-closing savvy : Comfortable stepping into the seat of the closer—owning qualification, negotiation, and hand-off to ensure deals progress smoothly and quota targets are met. Bonus: Prior SDR or RevOps/Revenue Engineering experience at an early-stage startup. Track record of exceeding outbound performance targets end-to-end. Who you are: Identify as a builder. Are excited to work in-person from our new and spacious office in New York. Love working in a startup environment (experience in a startup or obsession with going zero-to-one). Enjoy working with people who are ambitious, caring, and think in systems. Thrive in a fast-paced iterative environment where experimentation is essential.
