Using advanced AI and Open Banking data, we make fair, affordable personal finance available to more people. While traditional lenders rely almost entirely on credit scores, we look at the full financial picture - how much you spend, and what you can afford to repay to build a deeper, more accurate understanding of each customer's unique financial situation.\nAnd we've shown it works at scale. We’ve issued over £1.3bn in loans directly to customers while delivering market-leading credit performance - for every 10 defaults the industry expects, we see only 3. We also reached profitability just 2.5 years after launch.\nBacked by £2bn+ of funding from top-tier investors including Citi, GSR Ventures, and Deutsche Bank, we’re recognised as one of Europe’s fastest-growing fintechs (Sifted, CNBC). Now, we’re expanding into new markets and product lines - and we’re looking for ambitious people who want to learn fast, take ownership, and grow with us.\nAbout the role:\nYou won't be sitting in an ivory tower throwing policies over the fence. You will be embedded directly within our Platform team in a true DevSecOps capacity. Operating as a highly technical individual contributor, you will bridge the gap between product-led engineering and Corporate IT.\nYou will play a hands-on role in challenging the security architecture of production and corporate IT infrastructure.\nIn your first 6-12 months, you will design and implement our next-generation cloud security architecture across AWS and GCP, while helping to build and mature our internal SOC capabilities, including detection and response.\nYou will take ownership of Microsoft Sentinel, enhancing our SIEM/SOAR capabilities, and strengthen identity and access management through improved and automated RBAC across AWS, Microsoft Entra, and internal systems.\nYou will also drive a shift-left approach to security by embedding controls into GitLab CI/CD pipelines, including scanning, IaC reviews, and automated policy enforcement across the SDLC.\n\nOur technology stack:\nCloud & Compute: AWS, ECS Fargate, Aurora, Lambda, GCP\nData Lake: S3, DMS, Glue\nCloud Security Tooling: GuardDuty, Security Hub, Inspector, Security Command Center\nCode & IaC: Python, Java, GitLab, AWS CDK, Terraform/CDK-TF\nObservability & Incident Management: AMP, Incident.io\nWho you are:\nYou are a security professional by trade, but a hacker by design. You have a strong track record in DevSecOps and cloud security engineering, with hands-on experience elevating the security posture of other organisations.\n\n You are a strong Python developer. You know how to script automation, interact with APIs, and build security tooling from scratch.\n\nYou possess a rock-solid understanding of network security fundamentals and how they apply to modern, distributed cloud architectures.\n\nYou are comfortable owning both the build and run aspects of security-designing systems and responding to incidents.\n\n You thrive in the dynamic, ambiguous, and fast-paced environment of a high-growth startup. You know how to balance rigorous security with engineering velocity.\n\nWhat you'll be doing:\nActively contribute infrastructure-as-Code (AWS CDK, Terraform) for security risks prior to deployment\n\nImplement best practice network security across AWS and GCP (IAM, VPCs, encryption, logging, monitoring)\n\nEmbed zero-trust policies across the estate\n\nActively challenge the security standards of production applications and infrastructure\n\nEmbed security controls into CI/CD pipelines (SAST, dependency scanning, container security)\n\nPartner with engineering teams on secure architecture and deployment patterns\n\nSupport secure SDLC practices and pre-deployment security reviews\n\nWhat we offer\nEveryone owns a piece of the company - equity\n\nHybrid with 3 days a week in the office\n\n25 days’ holiday a year, plus 8 bank holidays\n\n2 paid volunteering days per year\n\nOne month paid sabbatical after 4 years\n\nEmployee loan\n\nFree gym membership\n\nTeam wellness budget to be active together - set up a yoga class, a tennis lesson or go bouldering","description_format":"text","description_chars":4128,"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":["Equity","Gym membership","Paid volunteering days"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Consumer Loans & Pawnshops"],"lifecycle":[{"event":"open","at":"2026-04-24T11:31:59Z"}],"visa":[],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.614,"p_room":0.36,"age_days":188,"expected_fill_days":98,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/abound-senior-security-engineer","json_url":"https://alion.io/job/abound-senior-security-engineer.json","meta":{"generated_at":"2026-10-31T00:37:43Z","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":844,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":450346},"rest":"https://alion.io/mcp/rest/get_company?id=450346"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fabound-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%2Fabound-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%2Fabound-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/abound-senior-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fabound-senior-security-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":69325}},{"tool":"search_jobs","arguments":{"company":"getabound.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":69325},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
