Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US.\nAs AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations.\nFollowing our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow.\n Location: Remote (US East Coast/Central)\nAs our team and customer base grow, we need to make sure our security efforts scale accordingly. For that, we are looking to expand the Synthesia Infosec team by onboarding an additional Security Engineer (L6)! You will report to the Head of Security and work within the Security Operations team.\nKey Responsibilities:\nBuild and own deeply technical security improvements across our Cloud Infrastructure(s) and associated territory (AWS/GCP, Kubernetes, CI/CD), including shipping production changes yourself when needed.\n\nDesign, implement, and iterate on detection and response capabilities (SIEM, EDR/MDR, cloud-native detections, CNAPP) with an engineer’s bias for automation, reliability, and measurable outcomes.\n\nHunt, investigate, and respond to security alerts and suspicious activity end-to-end (triage → containment → eradication → recovery → learnings), including writing tooling and detection logic to prevent recurrence.\n\nBuild internal security tooling and automations (IaC, scripts, integrations) that reduce toil and raise the security bar by default.\n\nExperience & Qualifications:\nYou’re a deeply technical security engineer with a builder/hacker mindset, able to go from idea → prototype → production and comfortable making changes directly in Cloud Infra / DevOps systems.\n\nYou have 5+ years of hands-on security engineering experience, ideally in a cloud-first SaaS environment.\n\nHave worked in a fast-growing startup, scale-up and/or SaaS company\n\nWe would expect you to have experience in:\nCloud security engineering in AWS and/or GCP, with the ability to implement improvements hands-on (IAM, networking, compute, storage, logging).\n\nKubernetes security (cluster hardening, workload isolation, runtime security, policy controls) and container ecosystems.\n\nDevOps fundamentals: CI/CD security, secrets management, artifact integrity, and secure-by-default platform patterns.\n\nIncident response and investigation, including creating repeatable playbooks and automating response where appropriate.\n\nStrong programming/scripting ability (Python or similar) plus comfort with infrastructure-as-code (e.g., Terraform) and automation.\n\nSerious agent coding - ideally you’re on the bleeding edge in the space.\n\nEndpoint security tooling, such as CrowdStrike\n\nBonus points for:\nHands on experience with any/all of: Hunters, Wiz, Falcon, Tracebit, Torii, Okta, Google Workspace, StrongDM, Github, StepSecurity, Dope Security\n\nAny relevant Information Security certification, e.g AWS Certified Security, GIAC GWEB, OSCP, or CSSLP.\n\nThe good stuff..\nIn addition to being a part of a great team, working in a fun and innovative environment, we offer:\nA competitive salary + stock options in our fast-growing Series E startup\n\nRemote-friendly environment\n\n100% Medical, Dental & Vision\n\n401k Plan\n\nPaid parental leave\n\n25 days of annual leave + Public holidays + paid sick leave\n\nFun culture with regular socials\n\nA generous referral scheme\n\nA brand new computer + monitor\n\nBudget and support for conference travel, community events, and content
