Technical Product Manager

• Portland, ME - Hybrid (Remote and In Person)

We’re looking for a senior, hands‑on Technical Product Manager to bring rigor and clarity to how we turn ideas into shipped product.

You’ll own backlog quality, requirements through approval, and the product‑definition and planning flow from direction into delivery. You’ll report to our Co‑Founder & CPO and work closely with our Director of Engineering, design lead, and senior engineers, in a scaling cybersecurity company where ownership is high, collaboration is close, and you’ll have meaningful influence over both the product and how we build.

This role is ideally based in Portland, Maine, with regular in‑person collaboration and flexibility for hybrid work. We’re open to exceptional remote candidates as well.

We’re building an industry‑leading cybersecurity platform. Defendify has been named to the Inc. 5000 list of America’s fastest‑growing private companies three years running, and we’re looking for a Technical Product Manager to bring rigor, consistency, and leverage to how ideas become shipped product.

This is a hands‑on role that owns requirements quality and how product direction moves into delivery, sitting at the center of how Product and Engineering work together. You’ll translate product direction and feedback into detailed requirements and specifications, identify ambiguity before it becomes rework, and maintain a healthy, prioritized backlog.

Depending on the work, you may develop requirements directly, refine drafts created with AI or Engineering, or build them collaboratively. In every case, you’ll review, challenge, edit, align the right stakeholders, finalize the requirements, and approve them before work moves forward.

We’re looking for someone with 5+ years of product or technical product management experience, ideally working full‑time on a live B2B software product and preferably in a security or technically oriented environment.

• Own product requirements, from initial concept through review, refinement, stakeholder alignment, and final approval, including acceptance criteria and related artifacts
• Ensure product intent, constraints, edge cases, dependencies, and success criteria are sufficiently clear before work advances
• Maintain a clean, structured, and prioritized backlog aligned to product direction
• Turn customer and internal feedback into actionable product work, identifying patterns that inform roadmap direction
• Partner with Engineering to evaluate implementation approaches and tradeoffs, keeping Product and Engineering moving in the same direction throughout definition and delivery
• Lead planning and product‑development flow while continuously improving how work moves from idea to production

The way software gets built is changing quickly, and we expect this role to embrace and drive that evolution within our team.

We are incorporating AI throughout the development lifecycle to accelerate work such as research, requirements development, prototyping, technical analysis, implementation, testing, and review. That may mean starting from an AI‑generated draft, collaborating with Engineering on a proposed specification, or using AI to challenge assumptions and uncover edge cases before development begins.

What does not change is accountability. Faster artifact creation makes sound product judgment, thoughtful review, clear decisions, and strong approval practices more important, not less.

• You help protect the consistency and conceptual integrity of the platform as it continues to grow
• Product direction consistently becomes clear, technically grounded, and actionable work
• Requirements are right‑sized for the problem,…
