Job Description - Senior DevOps Engineer

HALOS is an advanced body camera and cloud software scaleup, working with some of the biggest names in security, services, and law enforcement. At HALO, we're passionate about safety and innovation, constantly staying ahead of threats and reducing risk. 

What sets HALOS apart is not just the cutting-edge technology we develop but the culture we've nurtured. Our team embodies openness, transparency, and a "one team" spirit. We're a group of passionate individuals, all working on exciting and impactful projects. Here, you'll find an environment that fosters collaboration, creativity, and a shared sense of purpose.

As ourfirst dedicated DevOps specialist, you will be instrumental in shaping HALO’s DevOps
landscape from the ground up. You will architect and refine our monitoring and alerting strategies to achieve 99.99% uptime, guide our migration towards Infrastructure as Code (IaC) using AWS CloudFormation and CDK, and support the transition from Docker-based deployments into an ECS based environment. In addition, you’ll assist in our phased transformation from a monolithic architecture to an event-driven microservices ecosystem, ensuring our CI/CD pipelines incorporate advanced security and quality checks to support efficient, secure, and scalable software delivery.

Day to Day

    • Enhance and manage CI/CD pipelines, integrating sophisticated security and quality gates to facilitate reliable continuous delivery at scale.
    • Design, implement, and maintain robust monitoring, alerting, and observability solutions to ensure we meet and exceed 99.99% uptime targets.
    • Utilize AWS services and IaC tools, including AWS CDK, to build and maintain scalable, resilient cloud infrastructure.
    • Lead the migration of containerized applications to ECS, enabling dynamic scaling, improved resilience, and more efficient resource utilization.
    • Collaborate on the phased strangulation of a monolith into an event-driven microservice architecture, ensuring smooth transitions and minimal downtime.
    • Integrate advanced security reviews and compliance checks into pipelines to safeguard applications and data.
    • Develop automation scripts and tooling to streamline operational tasks, reduce manual overhead, and enhance system performance.
    • Proactively identify and resolve issues and work closely with product, development, and support teams to maintain a seamless, efficient workflow.

About You

    • Extensive experience with AWS services, cloud-based architectures, and IaC approaches (e.g. CDK written in Typescript).
    • A proactive approach to automation, with strong scripting capabilities for infrastructure and operations.
    • Deep understanding of security best practices in DevOps and cloud environments, with a proven record of integrating security into pipelines and deployments.
    • Solid background in Docker, ECS, and modern container orchestration solutions.
    • Familiarity with event-driven, microservices-based architectures, and the ability to support architectural transformations from monolith to microservices.
    • Strong troubleshooting skills and a passion for resolving issues efficiently to maintain system health and performance.
    • Effective communicator and mentor, comfortable collaborating in cross-functional teams and guiding junior engineers.
    • A continuous improvement mindset, thriving in fast-paced, evolving environments.

Your Qualifications

    • Minimum of 5 years’ experience in DevOps, Cloud Engineering, or a related role.
    • Relevant certifications (e.g., AWS Certified DevOps Engineer) are highly desirable.
    • Hands-on experience with CI/CD tools, development tools (Git, Bitbucket, JIRA), and methodologies (Agile, DevOps).
    • Strong knowledge of infrastructure automation and configuration management tools, with bonus points for experience working with AI infrastructure
