This person will understand how modern attackers discover, enter, persist, move laterally, exfiltrate data, and hide. They will continuously track active threat campaigns, newly exploited vulnerabilities, attacker tools, and changes in the global threat landscape, then convert that intelligence into practical defenses.\nThis is not a policy-only, advisory-only, or dashboard-only position. The successful candidate will make consequential security decisions, personally investigate suspicious activity, write production-quality detection and response code, interrogate network and endpoint telemetry, validate controls through authorized adversarial testing, and drive incidents to a technically sound conclusion. They must be willing to go deep enough to understand the vulnerability, exploit path, affected systems, attacker behavior, business impact, containment choice, and permanent corrective action.\nWhat you will do:\nThreat intelligence and attacker awareness\nContinuously monitor active threat campaigns, ransomware groups, state-sponsored actors, criminal ecosystems, exploit trends, malware families, phishing infrastructure, and newly weaponized vulnerabilities relevant to the company.\nTranslate threat intelligence into detection hypotheses, hunting queries, control changes, exposure reviews, and prioritized defensive action - not passive reporting.\nMaintain a current view of attacker tactics, techniques, and procedures using practical frameworks such as MITRE ATT&CK while recognizing where real-world behavior departs from frameworks.\nBuild trusted relationships with relevant industry, vendor, law-enforcement, and information-sharing communities as appropriate.\nEnterprise security architecture and attack-surface ownership\nUnderstand and secure enterprise routing, switching, segmentation, DNS, DHCP, VPN, wireless, firewalls, proxies, email, identity providers, directory services, SaaS, cloud, remote access, endpoints, servers, containers, and CI/CD environments.\nMap external and internal attack surfaces, trust boundaries, privileged paths, crown-jewel systems, internet exposure, shadow IT, third-party access, and plausible attack chains.\nDrive secure architecture decisions across identity, zero-trust access, network segmentation, secrets, cryptography, logging, endpoint protection, cloud controls, backup resilience, and recovery.\nPartner with infrastructure, product, software, IT, legal, privacy, and physical-security teams to reduce systemic risk without creating unusable controls.\nDetection engineering, coding and automation\nWrite, review, test, and maintain code that detects malicious or abnormal behavior across network, endpoint, identity, application, and cloud telemetry.\nDevelop behavioral analytics, correlation logic, enrichment pipelines, investigation tools, automated containment workflows, and repeatable forensic utilities.\nCreate high-quality SIEM/EDR/NDR detections and hunting content; measure precision, recall, coverage, false positives, alert latency, and operational value.\nUse languages such as Python, Go, Rust, PowerShell, shell, SQL, or equivalent as the problem requires; work comfortably with APIs, event streams, structured logs, packet data, and large security datasets.\nApply software-engineering discipline to security code: version control, peer review, tests, deployment controls, observability, rollback, documentation, and secure secrets handling.\nThreat hunting, insider risk and incident response\nProactively hunt for weak signals, anomalous sequences, living-off-the-land activity, identity abuse, covert persistence, unauthorized privilege, lateral movement, unusual data access, and exfiltration.\nInvestigate potential internal and external threats lawfully and proportionately, using authorized data sources, need-to-know access, privacy safeguards, and documented evidence handling.\nLead triage, scoping, containment, eradication, recovery, forensics, root-cause analysis, and post-incident improvement for serious events.\nPreserve evidence and timelines suitable for executive, legal, regulatory, insurance, and law-enforcement needs when applicable.\nDesign and run incident simulations, purple-team exercises, detection validation, and authorized adversary emulation; ensure findings become durable engineering improvements.\nVulnerability and exposure management\nOwn risk-based vulnerability management across infrastructure, endpoints, cloud, applications, dependencies, appliances, and third-party services.\nDistinguish theoretical severity from real exploitability by considering exposure, privileges, reachable attack paths, available exploits, compensating controls, asset value, and active exploitation.\nDrive remediation of critical weaknesses and validate fixes through retesting, telemetry, and control verification.\nEstablish emergency processes for zero-days and mass-exploitation events, including rapid inventory, containment, patching, workaround validation, and executive updates.\nLeadership and security operations\nAct as the company's senior technical decision-maker during serious cyber events. Decide when to isolate systems, disable accounts, block traffic, interrupt business processes, invoke outside support, or accept short-term operational risk - and document the evidence and reasoning behind those decisions.\nSet the technical direction, operating model, priorities, metrics, and quality bar for detection, response, threat hunting, vulnerability management, and security engineering.\nRecruit, mentor, and raise the capability of security engineers and analysts while remaining personally capable of deep technical investigation and coding.\nCommunicate risk in concrete business terms: what can happen, how likely it is, what evidence exists, what must be done, who owns it, and by when.\nBuild trusted escalation paths and an on-call model that supports decisive action without normalizing burnout or uncontrolled surveillance.\nDecision ownership and technical depth\nOwn security decisions from incomplete initial signal through validated conclusion; state what is known, what is unknown, the confidence level, the immediate risk, and the next decision point.\nDive personally into the highest-risk vulnerabilities and incidents. Read logs, inspect packets, trace identities and privileges, review configurations and code, reproduce issues safely, challenge assumptions, and verify that remediation actually closes the attack path.\nPrioritize vulnerabilities by real business exposure and attacker opportunity rather than CVSS score alone; connect individual weaknesses into plausible multi-step attack chains.\nRefuse both analysis paralysis and reckless action. Make reversible decisions quickly when possible, escalate irreversible decisions appropriately, and update direction as evidence changes.\nMaintain clear ownership through closure: containment is not completion. Require root cause, durable remediation, detection coverage, regression testing, and accountable follow-through.\nWhat you will bring to this role:\nSubstantial hands-on experience defending complex corporate environments and leading high-severity investigations from initial signal through containment and root cause.\nDemonstrated hacker mindset and practical knowledge of exploitation, persistence, credential theft, identity attacks, lateral movement, evasion, command-and-control, and exfiltration - applied only in authorized and ethical contexts.\nDeep understanding of TCP/IP, DNS, HTTP/TLS, routing, segmentation, firewalls, proxies, VPNs, wireless, endpoint internals, Windows and Linux, identity systems, cloud services, and enterprise logging.\nStrong programming ability and evidence of building security detections, analytics, automation, or investigation tooling used in real operations.\nExpertise with SIEM, EDR/XDR, NDR, IAM, cloud security telemetry, vulnerability tooling, packet/log analysis, and digital-forensics methods; vendor-specific experience is less important than first-principles understanding.\nAbility to reason from incomplete or conflicting evidence, form and test hypotheses, quantify confidence, and recognize when an alert is noise, an isolated event, or part of a larger campaign.\nDemonstrated record of making high-impact security decisions under time pressure and personally validating the technical evidence rather than delegating all analysis to vendors or junior staff.\nSound judgment regarding privacy, employee monitoring, legal authorization, evidence preservation, disclosure, and the boundary between defensive validation and unauthorized access.\nClear written and verbal communication with engineers, executives, legal counsel, employees, customers, and external responders during high-pressure events.\nBonus points:\nExperience in a technology company with valuable intellectual property, distributed operations, sensitive customer data, or high-availability infrastructure.\nDefense-industry cybersecurity experience is a plus, including supporting CMMC readiness and self-assessment, collecting and maintaining defensible control evidence, tracking remediation, and completing authorized self-reporting accurately and on time.\nExperience establishing or materially improving a threat-hunting, detection-engineering, incident-response, or security-operations function.\nBackground in reverse engineering, malware analysis, exploit analysis, cloud incident response, identity forensics, or network protocol analysis.\nExperience with threat-informed defense, purple teaming, security data engineering, and detection-as-code.\nRelevant research, open-source security contributions, conference work, responsible disclosures, certifications, or competitive security experience - valued as evidence, not substitutes for demonstrated capability.\nAdditional Requirements\nThis is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.","description_format":"text","description_chars":10116,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cybersecurity","Information Security","Space & Aerospace","Satellite Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-01T08:47:55Z"},{"event":"reopen","at":"2026-10-14T07:11:13Z"}],"visa":[],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.495,"p_room":0.44,"age_days":65,"expected_fill_days":52,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":220000,"is_top_pay":true},"html_url":"https://alion.io/job/espace-principal-cybersecurity-lead","json_url":"https://alion.io/job/espace-principal-cybersecurity-lead.json","meta":{"generated_at":"2026-10-18T05:58:28Z","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_verified","counted_by":"address","units_charged":1,"used_today":8958,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":2438005},"rest":"https://alion.io/mcp/rest/get_company?id=2438005"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fespace-principal-cybersecurity-lead"},{"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%2Fespace-principal-cybersecurity-lead"},{"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%2Fespace-principal-cybersecurity-lead"},{"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/espace-principal-cybersecurity-lead\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fespace-principal-cybersecurity-lead"}]}
