Desirable

• Halcyon is seeking a driven and detail-oriented Project Manager to join our Domain Engineering team. In this in-person role based in Austin, Texas, you will serve as the cohesive force that unifies security subject-matter experts with engineering subteams—specifically Cloud, Agent, and Quant—to ensure new security capabilities make it into our product on time and at high quality. You’ll own end-to-end project planning, execution, and communication within Domain Engineering, driving strategic alignment and continuous improvement so that Halcyon’s security domain knowledge directly shapes our roadmap
• End-to-End Project Planning & Execution:
• Define project scope, objectives, timelines, and deliverables for Domain Engineering initiatives, ensuring security requirements translate into clear workstreams for Cloud, Agent, and Quant teams
• Create and maintain detailed project artifacts (roadmaps, sprint backlogs, dashboards) that provide visibility into status, milestones, and dependencies
• Roll up your sleeves to track tasks, gather status updates from stakeholders, and proactively surface or remove blockers to keep projects on schedule
• Cross-Functional Collaboration & Stakeholder Management:
• Serve as the primary liaison between Security SMEs (threat researchers, architects) and the Cloud, Agent, and Quant engineering teams—facilitating working sessions, backlog refinement, and sprint planning so everyone shares a unified vision
• Coordinate regular stand-ups, demos, and retrospective meetings—ensuring action items are assigned, followed up on, and resolved in a timely manner
• Prepare and deliver concise status reports, risk/issue logs, and executive updates—using data and metrics to drive fact-based decision-making
• Requirements Translation & Quality Assurance Support:
• Partner with Domain Experts to translate high-level security concepts (e.g., new threat detection algorithms, vulnerability scanners, quant models) into actionable user stories and acceptance criteria for engineering
• Collaborate with QA teams to define test plans for security-focused features—monitoring defect trends, coordinating root cause analyses, and ensuring that compliance or regulatory artifacts are assembled for audits when necessary
• Process Improvement & Agile Coaching:
• Champion an Agile mindset within Domain Engineering—refining workflows, facilitating sprint retros, and introducing enhancements to increase team efficiency and collaboration
• Document and standardize best practices for handoffs between security, product, and engineering (e.g., requirement templates, definition of done checklists), driving continuous improvement in how we deliver security capabilities
• Collect metrics on cycle time, feature quality, and stakeholder satisfaction—using these insights to propose adjustments that help teams deliver sustainable value
