Technical Product Owner | Junior-Mid | Threat Protection at Nord Security

The world’s most advanced VPN, and a whole lot more.   If you’re a curious problem-solver who carves their own path, join the team behind Threat Protection Pro, the NordLynx protocol, and the fastest VPN on the planet—tools that put privacy, security, and control back in people’s hands. Your impact? Helping millions take back control of their online security, privacy, and data. NordVPN Threat Protection makes NordVPN more than a VPN. At its core sits a DNS-based filtering engine that protects millions of users from malicious domains, ads, and trackers — silently, at scale, in real time. We're looking for a Technical Product Owner who is technically curious, learns fast, and can quickly get to grips with network and DNS concepts — bringing structure, clarity, and momentum to a domain that scales to millions of users. Main Responsibilities DNS Filtering Product Ownership • Own the roadmap for DNS-based blocking — from resolver policy enforcement to user-facing filtering behavior. • Define and track core KPIs: hit count per category, hit density (blocklist length vs. actual hit count), DNS resolution latency, server uptime and query throughput. • Ensure clear ownership across the team — who decides what, and how trade-offs get resolved. Infrastructure Quality & Performance • Set performance benchmarks for DNS resolvers and hold the team to them. • Monitor response times, availability SLAs, and degradation signals across regions. • Translate infrastructure health into product outcomes: what does a latency spike mean for the user? Detection Pipeline & Release Quality • Own the process by which threat intelligence flows from the TI team into DNS filtering infrastructure. • Define release gates: what gets validated before a blocklist update reaches production, who signs off, and how rollbacks are triggered. • Track pipeline metrics: propagation latency, deployment success rate, rollback rate. Threat Intelligence Collaboration • Translate TI outputs into DNS filtering actions: what gets blocked, at what threshold, and how exceptions are handled. • Ensure clean handoffs between intelligence and enforcement — no ownership gaps between signal and production. Content Accessibility & Quality of Service • Collaborate with the Content Accessibility and Quality of Service teams to ensure filtering decisions do not degrade legitimate user access. • Act as the coordination point between DNS enforcement and accessibility concerns — balancing protection with usability. Competitive Intelligence & Product Direction • Monitor how industry leaders (Cloudflare, NextDNS, AdGuard, Quad9) approach DNS filtering and product capabilities. • Track social signals — Reddit and other community platforms — to surface emerging user complaints, overblocking patterns, and competitor perception; translate findings into proactive product actions. • Identify capability gaps and advocate for strategic product evolution. Core Requirements • Product ownership: Proven TPO or PO experience in a technical product environment • Technical aptitude: Fast learner with the ability to quickly grasp network concepts, DNS mechanics, and infrastructure trade-offs • Infrastructure metrics: Comfortable working with latency, uptime, and throughput data; able to spot patterns and ask the right questions • Detection pipeline: Able to define and improve structured processes — release gates, QA steps, rollback criteria • TI collaboration: Comfortable working alongside security/intelligence teams and translating their outputs into product actions • Overblocking awareness: Understands the user impact of false blocks; proactively builds measurement and prevention into the product process • Competitive mindset: Curious about the DNS/security space; proactively tracks what competitors are building • Communication: Bridges technical and non-technical stakeholders; writes clear specs and decision logs • Agile delivery: Experienced running sprints, managing backlogs, and iterating on roadmaps • English: Fluent — written and spoken Bonus Points For • Background in DNS security or network-level filtering • Familiarity with open-source blocklist ecosystems (OISD, AdGuard DNS filter, uBlock Origin) • Experience with DoH/DoT/DoQ and privacy-preserving DNS architectures Salary Range • Gross Salary 3500 - 5700 EUR/Month What We Offer Innovate with industry leaders Work alongside global experts to build world-leading cybersecurity tools, impacting millions of users around the world.
