About The Team

We're a fast-paced, interdisciplinary team working on multiple tech projects simultaneously. Our team is diverse and works on different products and nesto experiences that are all interconnected.

We are looking for a Senior Security Developer to join our dynamic team. In this role, you will play a critical role in designing, implementing, and maintaining cloud security solutions to protect our cloud-based systems and applications. You will work closely with our development and operations teams to ensure the security and integrity of our cloud infrastructure.

We celebrate a variety of perspectives and experiences. We are not looking for someone who checks every single box - we’re looking for lifelong learners and people who can make us better with their unique experiences.

What You'll Be Doing

Implement and maintain robust security controls to protect our cloud infrastructure and applications.
Discover, remediate, and validate security issues across cloud infrastructure.
Perform architectural/design reviews through a security lens and provide timely, actionable requirements and recommendations.
Collaborate with security leadership, compliance, and engineering teams to execute security strategies.
Build, deploy, and manage security tools such as WAF, IDS/IPS, workload protection, GCP Command Center, and Azure Security Center, etc.
Propose and contribute to security and compliance improvements for nesto CI/CD pipelines and deployment processes.
Automate infrastructure provisioning and deployment processes using Infrastructure as Code (IaC) tools like Terraform or Pulumi.
Design and operate scalable processes to provision cloud access and maintain least privilege.
Participate in and support the incident detection and response process by enhancing observability and alerting and assisting the incident response team.
Self-organize and prioritize activities independently.
Support audits and first-party security questionnaires.
Conduct and oversee security assessments and threat modeling exercises.
Implement security controls within Kubernetes.
Build DevSecOps tools/integrations.

Who We're Looking For

5+ years of experience working on a team focused on infrastructure and/or security.
5+ years of development experience (ideally GoLang, TypeScript/JS).
Knowledge of common web application vulnerabilities and the OWASP Top 10 framework.
The ability to analyze and act on results from DAST and SAST tools (e.g., Tenable, Snyk).
Skilled in DevSecOps principles and familiarity with CI/CD pipelines (GitHub Actions, Argo CD, Azure DevOps) to perform automated security testing.
Experience deploying and customizing security tools to address threats and lower risk, including vulnerability scanners, static analyzers, web application firewalls (WAFs), intrusion detection/prevention systems (IDS/IPS), and endpoint security monitoring.
A comprehensive grasp of cloud and network security, including an in-depth understanding of Kubernetes.
Experience in GCP specifically with one or more of the following services: Security Command Center, GKE, Cloud IDS, Cloud Armor, and Secrets Manager.
Experience in Azure specifically with one or more of the following services: Security Center, Azure PaaS App Services, VMs, Azure SQL, Front Door, and Key Vault.
Experience writing infrastructure-as-code using tooling such as Terraform, Pulumi, and Helm.
Knowledge of common security-related frameworks and benchmarks like CIS, NIST, and MITRE ATT&CK.
An understanding of identity and access management (IAM) principles and cloud-native IAM solutions.
Passionate about constant learning and sharing knowledge with others.
Bilingual (English & French).

We definitely want to talk to you if you have/are

Experience managing security posture by collating, digesting, and monitoring outputs from tooling.
Experience working with infrastructure-as-code using tooling such as Terraform, Pulumi, and Helm.
Skilled in DevSecOps principles and familiar with CI/CD (Github Action and Argo CD) pipelines to perform automated security testing

The Reward

The A-Team: Work alongside high-performing talent in the industry.
Accelerated Growth: The slope of your learning curve here will be vertical. You will touch more production systems in one year than you would in five years at a bank.

Rest & Recharge: 4 weeks of vacation to ensure you stay at peak performance.
Best-in-Class Tools: Access to the resources and tech you need to execute without friction.
Working framework: The environment that makes you productive and enables teamwork (Hybrid model).
