MTS: AI Research Engineer
<p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>Type:</strong> Full Time, Hybrid</p><p style="min-height:1.5em"><strong>Team:</strong> Research</p><p style="min-height:1.5em"><strong>Focus:</strong> AI & Agent Systems</p><p style="min-height:1.5em"></p><h2>Who We Are</h2><p style="min-height:1.5em">We're a team of founders, engineers, researchers, creatives, and operators building what we believe will be one of the defining companies of the AI era.</p><p style="min-height:1.5em">Some of us came from startups. Some from academia. Some from hospitality, defense, design, or completely different worlds. We don’t care how you got here - we care about your energy, intelligence, curiosity, resilience, and ambition.</p><h3><br /></h3><h3><strong>Who We Are Not</strong></h3><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><em><strong>We are not remote.</strong></em> We value the spontaneous moments that happen when we’re together - over dinner, in the hallway, around whiteboards. We like being around each other because the best conversations here rarely happen in meetings.</p></li><li><p style="min-height:1.5em"><em><strong>We are not your typical team.</strong></em> It’s not just the 10 countries we’re from, the languages we speak or our non-traditional backgrounds. We’re solving hard problems with people we respect - we make the most of our time together, we make it special.</p></li><li><p style="min-height:1.5em"><em><strong>We are not another “polished” SF startup</strong></em><strong>.</strong> We value velocity over speed, raw talent over brands, and genuine human connection above all else. We value being successful, not looking successful.</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"></p><h2><strong>What You’ll Own & Build</strong></h2><p style="min-height:1.5em">As a Member of Technical Staff within the Research Tribe, you’ll be one of the early engineers shaping the core systems that power Seldon.</p><p style="min-height:1.5em">You won’t just build agents - <strong>you’ll design the infrastructure that governs how they operate: how they coordinate, how they’re evaluated, and how their behavior improves over time</strong>.</p><p style="min-height:1.5em">This is a deeply technical role bridging distributed systems, machine intelligence, and product - turning stochastic models into reliable, production-grade systems.</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Multi-Agent Systems Architecture:</strong> Design and implement agentic systems, rather than prompt chains, at scale. You’ll define agent topologies, robust orchestration layers, structured state management, persistent and scoped memory, tool-use registries and execution, and build structured, inspectable systems. <strong>You’re building a long-running harness-based agentic platform, not wiring together LLM API calls.</strong></p></li><li><p style="min-height:1.5em"><strong>Behavioral & Persona Modeling:</strong> Simulate user archetypes with goal-directed behavior. You’ll design data-grounded personas, enable “computer-use” on real interfaces, and develop agents with critique and reflection loops. <strong>You’re producing measurable, actionable behavior.</strong
