Right now we’re looking for a Senior Security Engineer to play a key role in our Security team in Athens. If that’s you, and making a difference gets you out of bed in the morning, keep reading. It could be the start of something, well, extraordinary.\nAs our Senior Security Engineer you’ll help keep our platform and our customers’ data safe by watching our security tooling closely and acting on what it tells us, as we work towards ISO certification. You’ll join a small security team where you can take initiative and potentially own projects from start to finish.\nSounds great, what will I be doing? \nMonitor and triage alerts and logs across our security tools, and take operational action on findings rather than waiting for direction.\nTrack vulnerabilities end to end, keeping clear records of actions, owners and deadlines across teams.\nHelp produce the operational evidence for our ISO certification by documenting what we monitor and what we do about it.\nDrive decisions on alerts, including web application firewall alerts, working with IT, DevOps, Engineering and Legal.\nContribute to team initiatives, including automating repetitive security work.\nWhat do I need to bring with me?\nYou’ll need to be able to demonstrate the core skills this role requires. You don’t have to tick all the boxes right away; the important thing is that you’re willing to learn. Here’s what the team will be looking for in you:\nComputer Science background: A degree in Computer Science or equivalent practical experience.\nSecurity experience: 4+ years of hands-on experience in security.\nCode literacy: You can read code and write scripts to investigate findings and automate repetitive work (Python or Golang preferred).\nInitiative and communication: You pick up findings without being asked, reply promptly, and join cross-team calls with confidence.\nNice to have:\nExposure to ISO 27001 or security audits\nExperience with a cloud provider (AWS, GCP, Azure or similar)\nExposure to IT or DevOps, and the security best practices that go with them\nEqually important is attitude. We want people who think big (to make an impact), ask why (to find a better way), and show respect (to everyone, at every level, all the time). Those are our values, exemplified by our leadership team, and they’re a big part of what we’re looking for in you.\nDiversity, Equity & Inclusion\nDiversity is fundamental to who we are-as a data company and as a workplace. Our data reflects global realities, and so must our teams. We strive to build a workforce as diverse and inclusive as the insights we deliver.\nAs a Disability Confident employer, we welcome applications from disabled candidates and are committed to making adjustments throughout the hiring process-whether that's extra time, materials in advance or a different format, breaks, an adjusted interview format, assistive tools, or flexible scheduling. We're happy to discuss whatever would work best for you.\nWe actively encourage applications from underrepresented and marginalised communities.\nAt GWI, you'll find a place to contribute meaningfully, grow professionally, and belong fully.","description_format":"text","description_chars":3441,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Equity"],"hiring_locations":[{"name":"Greece","iso":"GR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Data Providers & Datasets","Market Research"],"lifecycle":[{"event":"open","at":"2026-10-16T18:40:23Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":53,"reasons":["conf:3","win:early"],"computed_at":"2026-10-17T05:40:04Z"},"pay":null,"html_url":"https://alion.io/job/gwi-senior-security-engineer","json_url":"https://alion.io/job/gwi-senior-security-engineer.json","meta":{"generated_at":"2026-10-17T05:40:04Z","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":7654,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":719978},"rest":"https://alion.io/mcp/rest/get_company?id=719978"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgwi-senior-security-engineer"},{"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%2Fgwi-senior-security-engineer"},{"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%2Fgwi-senior-security-engineer"},{"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/gwi-senior-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgwi-senior-security-engineer"}]}
