Salary: $200,000 - $285,000 per year A bit about us: We're an early-stage AI technology company building production-grade agentic systems for complex, high-stakes environments. Our platform combines frontier AI with deep domain expertise to help organizations understand complex information, make better decisions, and take action. Backed by leading institutional investors, our team is building foundational AI infrastructure from the ground up with significant technical ownership and direct collaboration with the founders and CTO. Why join us? Equity / ownership: Meaningful upside as the company grows. Direct access to founders and CTO: This role reports directly to the CTO and works closely with the founding team. High technical ownership: Own core agent-runtime infrastructure rather than a small component of a mature product. Frontier agentic-AI work: Build production agents involving long-running workflows, memory, retrieval, model routing, tool use, evaluation, and security-not simply LLM API wrappers. Early-stage impact: Materially influence architecture, engineering standards, and product direction. Strong founding team: Leadership backgrounds include senior roles across government and major technology organizations. Well-funded startup environment: Institutional backing provides the resources to build ambitious technology while retaining early-stage ownership and impact. High-impact customer exposure: Build AI systems supporting government, policy, procurement, and other complex, high-stakes environments. SoHo / NYC office: Work directly alongside the technical and founding teams in a highly collaborative environment. Job Details Staff / Senior Software Engineer - Agent Engineering Location: SoHo, New York City Work Arrangement: In-person, 5 days per week Employment Type: Full-time Compensation: Up to $285,000 base salary for Staff-level candidates, based on experience, plus equity TWO ROLES Senior Software Engineer - Agent Engineering Looking for someone who has strong production software engineering experience plus meaningful hands-on experience building LLM/agent systems in production. They should have experience in several of the core areas-agent orchestration, tool use, RAG/context engineering, memory, evaluation/observability, model integration, or production reliability-but don't necessarily need to have owned the entire agent platform architecture themselves. Staff Software Engineer - Agent Engineering Looking for someone who has already architected and owned significant portions of production agent infrastructure. This person should be capable of setting technical direction around long-running/stateful agent execution, tool/action frameworks, persistent memory/context, model routing, evaluation, security, observability and failure recovery. They should be comfortable making architecture-level decisions and driving foundational systems across the engineering organization. About the Company We are building a new kind of technology company focused on solving complex, high-impact problems, beginning with the way organizations interact with government. Government influences nearly every consequential market, yet the infrastructure connecting public institutions and private organizations remains fragmented, manual, and difficult to navigate. Our mission is to rebuild that interaction layer. Our core platform provides organizations with the intelligence they need to understand what government is doing, why it matters, and what actions to take next. From that foundation, we design and deploy secure, mission-specific systems for government agencies, enterprises, and institutions operating in complex and highly regulated environments. We combine frontier AI, deep public-sector expertise, and forward-deployed execution. Our team includes experienced leaders and engineers from major technology companies and senior government organizations. We are backed by leading institutional investors and trusted by organizations working on high-stakes challenges across government and industry. The Mission We are seeking a Staff/Senior Software Engineer specializing in Agent Engineering to advance the agent runtime powering our platform's research, analysis, and action capabilities. Our agents must be capable of decomposing open-ended objectives, retrieving trustworthy evidence, safely using tools, coordinating long-running work, and producing high-fidelity outputs that remain traceable to their sources. You will own and improve the systems that make agent behavior reliable in production, including: Execution state and orchestration Tool use and permissions Context and persistent memory Model routing Failure recovery Evaluation and observability Security and operational controls The goal is to enable agents to perform meaningful work over extended periods without losing context, exceeding their authority, silently failing, or producing unsupported conclusions. You will also advance the platform's reasoning and memory layer, enabling agents to accumulate knowledge, recognize changes, resolve contradictions, and maintain direct source context across workflows. What We're Looking For We're looking for an experienced engineer who has beyond the prototype stage. You should be comfortable diagnosing nondeterministic failures, establishing clear boundaries between model judgment and deterministic software, and determining when workflows require autonomous execution, human approval, or conventional application logic. Ideal experience includes: Production orchestration of stateful, long-running, and multi-agent workflows Tool and action infrastructure with strong contracts, permissions, and approval boundaries Retrieval, context engineering, evidence management, and persistent agent memory Model-runtime engineering across multiple providers, latency profiles, and deployment environments Evaluation, tracing, security, and operational control of nondeterministic AI systems Designing reliable systems around LLM behavior in production environments Key Responsibilities Own and advance the platform's agent runtime and foundational systems used to build new agent-driven products. Build infrastructure that allows agents to manage long-running work from initial assignment through completion while keeping activity visible, steerable, and connected to relevant projects, people, evidence, deadlines, and deliverables. Design and build the tool and action framework agents use to safely interact with internal systems and external services. Connect agents to retrieval and knowledge systems so reasoning, memory, citations, and generated artifacts remain grounded in authoritative evidence. Build and improve persistent memory and context-management systems for complex, multi-step agent workflows. Strengthen evaluation, tracing, simulation, and release processes for agent behavior. Improve agent quality and reliability while managing latency, inference cost, security, and operational risk. Diagnose and resolve complex production failures involving nondeterministic AI systems. Nice to Have Experience deploying agent systems in government, defense, legal, healthcare, financial services, or other highly regulated environments Familiarity with policy or legal research where temporal accuracy, provenance, and citation precision are critical Experience operating self-hosted or multi-provider inference in restricted environments Experience building agents that create durable artifacts or perform permissioned actions on behalf of users Experience designing secure AI systems involving human-in-the-loop approvals and authorization boundaries Working Here This is a full-time, in-person position in SoHo, New York City, with team members expected to work from the office five days per week when not deployed with customers. Certain customer engagements may require background checks, security reviews, access approvals, or eligibility for a U.S. government security clearance. Some projects may also be subject to U.S. citizenship or other customer-specific access requirements. We're looking for driven builders who want to create systems from the ground up and push the boundaries of agentic AI, natural language understanding, document intelligence, reasoning, and personalized relevance. This is a fast-moving startup environment with ambitious goals and significant ownership. It is not a conventional 9-to-5 role. Flexibility may be required during critical deployments, customer incidents, product launches, and other company-critical periods. In return, this position offers substantial technical ownership, direct access to consequential customers and institutions, and the opportunity to build AI systems that influence how important decisions and work get done. How We Work Own outcomes, not just tasks. Identify what needs to happen and drive it through completion. Move quickly without lowering the standard. Speed and rigor should reinforce one another. Stay close to the mission and the user. The best technical decisions start with understanding the real problem. Work across boundaries. Everyone contributes beyond the narrow limits of their job title. Communicate directly. We value clear thinking, candid feedback, and low-ego collaboration. Build for the real world. Our systems must perform reliably in complex, regulated, and high-stakes environments. Interested in hearing more? Easy Apply now by clicking the "Quick Apply" button.
