Harmonic Security governs all of it. The AI Governance and Control (AIGC) platform understands user / agent intent and data context in real time, giving security teams visibility and control across every tool and workflow so companies can move faster with AI while minimizing risk.\nWe operate in one of the fastest-moving spaces in tech: the emerging intersection of AI and cybersecurity. It's a market still being defined, and we're among the first to build natively for it - protecting sensitive data in real time, at the endpoint, with minimal friction for the teams using it. Enterprises get full visibility and control. Their people get to innovate without guardrails slowing them down.\nNamed to the Rising in Cyber 2026 list, Harmonic is gaining serious recognition and serious traction. We're led by deep cybersecurity expertise and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel.\nAs AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.\nHow We Work: AI-First by Design\nHarmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively leverages AI tools to perform their best work, from deep research and writing to building robust processes and automating complex workflows. We expect every new hire to bring a genuine curiosity for AI and a commitment to using it to work smarter, faster, and with greater creativity.\nFor some, this involves tinkering and remaining open to emerging tools; for others, it means architecting entirely new systems with AI at the core. We will be transparent about expectations for every role and provide the tools and support needed for you to thrive.\nThe Role\nWe're looking for a Staff Product Manager to take full ownership of a product area focusing on AI Surfaces - the ever-evolving set of places, tools and apps where AI governance has to operate. This is a broad, high-leverage part of what Harmonic builds and sells. You'll be the person who decides which outcomes matter most, in what order we go after them, and be accountable for the value delivered to our customers and our business.\nThis isn't a role where the strategy arrives fully formed and your job is to deliver it. The market we operate in is changing week to week, and often in ways nobody predicted. A large part of this role is forming a view on where it's heading before all of the evidence is conclusive, committing to that view strongly enough that the team can act on it, and adapting your view when things inevitably change.\nWhat You'll Do\nOwning a product area end to end, from deciding where it should go over the coming year to the detail of what ships next, and being able to explain and defend the reasoning behind both.\n\nBuilding and holding a point of view on where your part of the market is going, grounded in what you're hearing from customers, what competitors are doing and how the technology itself is moving.\n\nDeciding which outcomes in your area deserve investment and in what order, and setting out clearly what success looks like so that we can tell honestly when something is or isn’t working.\n\nSpending a real share of your time with existing customers and prospects, on sales calls, in proof-of-value engagements, being comfortable leading those conversations with different types of people such as CISOs, CIOs and the people who work for them.\n\nCollaborating closely across the business, particularly with engineering, design, sales, customer success, so that you can influence decisions well beyond your own team without needing formal authority to do it.\n\nGetting hands-on at the solution level, whether that means exploring an API, pulling and interrogating data yourself, or testing an idea yourself before committing engineering time to it.\n\nRaising the bar for how product work gets done here, so that the way you frame problems, write things down and make decisions becomes something other people start borrowing.\n\nWhat You'll Bring\nYou've owned something substantial before, a product area or a connected set of problems where you set the direction rather than inheriting it. You'll also have strong conviction, because in a market moving this quickly, waiting for certainty often means arriving late. We need someone who is willing to say where they think things are going and stand behind it, while being honest enough with themselves to change course when the evidence tells them otherwise. We would much rather hear a clear view that turns out to be wrong than an overly careful one that rarely commits to anything.\nYou're also energised by the reality of a startup, where priorities shift, information is incomplete and a lot of what you'll need doesn't exist yet, which means you'll often be building the product and the way of working around it at the same time. If that sounds like a frustration rather than the appeal, this probably isn't the right role for you.\nNice to have\nExperience in B2B, particularly selling to and working with large enterprises.\n\nA background in security, data protection or a related field. This isn't a requirement, because we care far more about how quickly you can get to grips with a domain than whether you already know this one.\n\nExperience with products that are enabled via an endpoint agent.\n\nYou live and breathe AI trends and latest developments to apply it directly in your role\n\nWhy Join Us\nThis isn't just a job - it's a chance to help define a category. Harmonic Security was named to the Rising in Cyber 2026 list, and we're just getting started. We're building at the intersection of AI and security, carving out an emerging market where the rules haven't been written yet, and the people who join now will write them.\nWe believe today's talent is tomorrow's success, and we're committed to creating an environment where you can do the best work of your life.\nRecognized momentum - We made the Rising in Cyber 2026 list, a signal that the market is taking notice\n\nRare market opportunity - Join early in a category-defining company at the convergence of AI and security, where your work directly shapes how enterprises tackle one of the biggest unsolved problems in tech\n\nCompetitive pay and meaningful equity - A real stake in Harmonic's success, not a token gesture\n\nComprehensive benefits - pension plan and flexible hybrid work\n\nA small, high-trust team that values transparency, creativity, and continuous learning - no politics, no bureaucracy\n\nThoughtful leadership - that cares deeply about your growth, not just your output\n\nAnnual global off-sites - past trips include Lisbon, Portugal and Nashville, TN\n\nReal ownership - you'll shape the product, the culture, and the direction of the company from day one\n\nHarmonic's Core Values\nFlourish in the Unknown\nWe embrace new, unfamiliar situations that require initiative and rapid decision-making. We orient ourselves quickly and deliver results with minimal guidance.\nNever Full\nWe raise our hands, take on challenges, and assist others whenever possible. We hunger for opportunities to learn and do more.\nPerfect Harmony\nWe support one another to create cohesion and unity. We collaborate openly, share feedback honestly, and help everyone produce their best work","description_format":"text","description_chars":7415,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Continuous learning","Equity","Hybrid work"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Information Security","Data Loss Prevention","Cybersecurity AI","AI Governance & Compliance"],"lifecycle":[{"event":"open","at":"2026-10-03T16:34:11Z"}],"visa":[],"liveness":{"score":85,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.901,"p_room":0.945,"age_days":6,"expected_fill_days":11,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/harmonic-security-staff-product-manager","json_url":"https://alion.io/job/harmonic-security-staff-product-manager.json","meta":{"generated_at":"2026-10-11T04:29:24Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":3191,"day_limit":5000,"remaining_today":1809,"minute_limit":60,"resets_at":"2026-10-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":63228},"rest":"https://alion.io/mcp/rest/get_company?id=63228"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fharmonic-security-staff-product-manager"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fharmonic-security-staff-product-manager"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fharmonic-security-staff-product-manager"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/harmonic-security-staff-product-manager\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmonic-security-staff-product-manager"}]}
