It’s why Glia customers quickly and confidently put Banking AI to work with measurable results from day one. More information about Glia can be found at glia.com .

The DevSec team owns developer-facing and platform security at Glia - building guardrails and paved paths that let product teams move fast, safely. There is a saying in Glia: security is not just a feature, it's a part of our service.

The role

We're looking for a Senior Security Engineer who thinks about security end to end - not one domain deep, but the whole posture: application, infrastructure, supply chain, endpoints, operations, and the compliance surface behind them.

This is a Team Lead hire: we're looking for someone who will lead the DevSec team. You will start as a hands-on individual contributor to learn Glia's systems and security specifics, then step up to lead the team as a player-coach - leading the team's delivery and growth while remaining deeply hands-on, with career progression on the engineering IC track.

The Ramp-Up (First 3 Months)

You will start as a hands-on Senior Security Engineer to build a strong foundation. You will:

  • Ship hands-on security work and learn Glia's platform, Glia-specific security challenges, and how the rest of the Platform group operates.
  • Co-own the company security roadmap together with our Security Leader, balancing domains by risk.
  • Get to know the team, our tooling, and Glia's project delivery methodologies.

The Team Lead Role (Post Ramp-Up)

Once you step up, your time will shift to ~60% leadership and ~40% hands-on work. You will own:

  • Delivery & roadmap: own security programs end-to-end - from roadmap shaping and stakeholder alignment through implementation and adoption - prioritising by risk and unblocking the team.
  • People & mentorship: run 1:1s, manage performance, and grow the team.
  • Hands-on contribution: lead by example - stay close to the technical work and take on high-leverage security engineering yourself.

The Work

The role spans the whole security surface, prioritising by risk rather than by specialty:

  • Application & product security - threat modelling, secure SDLC, design/code review, supply chain security
  • Infrastructure & cloud security - AWS posture, runtime security, IAM; close collaboration with the Infrastructure team
  • Security automation & AI - develop and own automation and AI tooling supporting company security goals; secure our AI-assisted development practices and LLM tooling
  • Endpoint & corporate security - developer endpoint security (MDM, privilege, software governance), secrets hygiene
  • Whole-posture assessment - run framework-based assessments (CIS Controls), identify where attention bears most value, and turn findings into prioritised, engineering-consumable plans
  • Compliance interface - connect technical work to SOC 2 / PCI-DSS / ISO 42001 needs
  • Mentor engineers, lead blameless post-mortems for security incidents, and present to and align senior management

DevSec is part of the Platform group and works closely with Infrastructure, Developer Acceleration, and Observability. The team is remote-first with fully remote rituals - we have team members in Estonia and Poland today.

Tech Stack you will be working with

  • Infrastructure: AWS (Terraform, Kubernetes)
  • CI/CD: Jenkins, GitHub Actions, ArgoCD
  • Vulnerability detection & runtime security: Snyk, Sysdig/Falco
  • SSO & MDM: Okta, Jamf
  • Coding: Python preferred; our product stack includes Elixir, Ruby, and Golang
  • AI-assisted development: Claude Code and agentic tooling are part of everyday engineering at Glia

Requirements

  • Credible hands-on experience in at least two security domains (e.g. AppSec + cloud/infra) and literacy across the rest - you think in overall posture and risk, not tools
  • You have built or scaled a security program end-to-end (process, tooling, adoption), ideally in a low-structure environment
  • Coding and automation ability (Python preferred) and cloud security depth (AWS)
  • Experience with AI-assisted development, and with securing it: LLM tooling (e.g. MCP), AI governance awareness
  • Leadership readiness with evidence - mentoring, deputising for a lead, or formal lead experience - and the commitment to step up as DevSec Team Lead after ramp-up, owning the team's delivery while staying technical
  • An educator and multiplier, not a gatekeeper: you enjoy high-empathy collaboration with developers
  • Located in Europe

Nice to have

  • Framework-based posture assessment experience (CIS Controls, NIST CSF, or similar) - you can run an assessment and turn it into a prioritised roadmap
  • Pentest, audit, and compliance exposure (SOC 2, PCI-DSS, ISO 42001)
  • Terraform/Kubernetes; endpoint/MDM and IdP experience

Other security roles worth a look

A few links on CyberJobs.cc are referral links: when one leads to a hire, a sign-up or a purchase (a lab, a course or a tool marked Partner), the company behind it may pay CyberJobs.cc a fee. You pay nothing extra, and it never changes the salary an employer offers you or which roles the board lists. Roles from partners who pay us a fee rank a little higher in this list.

Run a security team before?

Security teams sometimes ask us directly for someone with a given specialty, clearance or certification. Join the candidate pool once and we put you forward when a brief matches, and only after you say yes. No cost to you.
