Technical Product Manager at Defendify in Portland, ME

Job description

• Bring clarity to what we build.
• Shape how we build it.
• TL;DR
• 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.

Responsibilities

• 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

Requirements

• Are an exceptional communicator, particularly in writing
• Think deeply about systems, workflows, dependencies, prioritization, and downstream impact rather than operating only at the feature level.
• Have strong experience developing, reviewing, and finalizing product requirements and specifications in a production software environment
• Are comfortable engaging with technical documentation, system designs, and implementation tradeoffs, and enjoy working closely with engineers to challenge, clarify, or bring in deeper expertise when needed
• Can take a rough idea and systematically turn it into something Engineering can build
• Are comfortable making decisions and standing behind the quality of the work that moves forward
• Use AI tools fluently in your own work and are actively developing your point of view on how AI is changing modern product development
• Bring a security-first mindset to product decisions
• Work well in an environment with high ownership, close collaboration, evolving priorities, and the opportunity to influence how the team operates

Skills

Required

• A timely opportunity: Help define how our evolving product organization builds in the AI era
• A proven growth company: Join an Inc. 5000 honoree recognized for three consecutive years
• A meaningful mission: Help make cybersecurity possible for small and midsized organizations facing growing security demands
