Job summary

Voi Technology AB is seeking a Senior Platform Engineer to own the security toolchain across the software delivery lifecycle. You will work with the Platform & Information Security team to turn security into a paved road used by delivery teams, leveraging GCP, Go, GitHub Actions, ArgoCD, Grafana, and more.

You will harden defaults, build guardrails, and drive security KPI dashboards while addressing risks in AI-generated code and evolving attack surfaces.

Qualifications

• Experience building secure software delivery pipelines across multiple repos or services.
• Strong understanding of OWASP Top 10 and secure SDLC.
• Hands-on with AppSec tooling such as SAST/ SCA/ secrets scanning (GitHub Advanced Security, Snyk or similar).
• Experience with Kubernetes and cloud infrastructure (GKE/GCP or equivalent).
• A builder's instinct; prefer shipping guardrails over long policy docs.

Responsibilities

• Verifying and triaging SAST, secret scanning, and dependency alerts, tuning rules to cut false positives.
• Hardening paved-road service templates with secure defaults and gates.
• Building CI/CD security guardrails: signed builds, SBOM pipelines, deploy-time checks.
• Building and maintaining security KPI dashboards for engineering and leadership visibility.
• Proactively reviewing and hardening infrastructure and AI-generated code safety.
• Evaluating AI capabilities to improve proactive and reactive security responses.
• Enabling Security Champions with tooling and guidance.

Job description

YOUR MISSION AT VOI

As Senior Platform Engineer, you'll own Voi's security toolchain end-to-end across the software delivery lifecycle. You'll join our Platform & Information Security team, working alongside platform engineers and security champions embedded across engineering, turning security from a checklist into a paved road that delivery teams actually want to use.

Our stack includes GCP, Golang, GitHub Actions, ArgoCD, Grafana, Prometheus, Mimir, and Jaeger. We're in the middle of rolling out GitHub Advanced Security as our core AppSec toolchain, and increasingly need to reason about risk in code that's partly or wholly AI-generated, both defensively (reviewing it) and offensively (AI-assisted attacks are already showing up in our bug bounty inbound).

THIS WILL INCLUDE

• Verifying and triaging SAST, secret scanning, and dependency alerts, tuning rules to cut false positives, and partnering with code owners to remediate findings across all repos
• Hardening our paved-road service template so secure defaults (secrets handling, authn middleware, observability, security-checks-pass merge gates) are the easy path, not an opt-in
• Building CI/CD security guardrails: signed builds, SBOM pipelines, deploy-time policy checks, provenance.
• Building and maintaining security KPI dashboards for engineering and leadership visibility
• Proactively reviewing and hardening infrastructure and application security including addressing risks in AI-generated code
• Evaluating and implementing AI capabilities to drive proactive and reactive response in a world where offensive AI capabilities are commonly available.
• Enabling our Security Champions with tooling and guidance, not just policy

WHAT YOU NEED TO EMBARK

• Fluency in a backend programming language (Go strongly preferred, given our stack)
• Solid understanding of application security fundamentals (OWASP Top 10, secure SDLC)
• Hands-on experience with AppSec tooling: SAST, SCA, or secrets scanning (GitHub Advanced Security, Snyk or similar)
• Experience with Kubernetes and cloud infrastructure (GKE/GCP or equivalent)
• A builder's instinct, you'd rather ship a guardrail than write a policy doc

WHY VOI?

Working at Voi is more than just a job; our People Promise includes a personal voyage where you will grow as a professional and be a part of a team and culture that builds something meaningful for society. In addition to this you’ll have the opportunity to:

• Join Europe’s #1 micromobility operator and one of the fastest-growing scaleups.
• Get "skin in the game" through our employee stock options program and play a key role in driving continued success in Germany - Europe's biggest market.
• Be part of a supportive, motivated and fun team working together towards a shared mission.
• Join the micromobility revolution and be a part of creating sustainable cities made for living, free from noise and pollution.
