#RunwiththePack At Arctic Wolf, we’re on a mission to end cyber risk . We are a global leader in security operations, helping organizations stay resilient against evolving cyber threats through industry-leading security operations, threat intelligence, and a people-first approach to cybersecurity. More than 3,000 Pack members across the world work together every day to protect our customers and empower security teams with new levels of speed, accuracy, and intelligence at scale. What sets us apart is our relentless focus on our customers, innovation at scale, and a collaborative culture where talented people can do meaningful work that truly makes a difference. We’re constantly looking for talented people to join the Pack and help us take our performance to the next level. About the Position: Job Description We’re looking for a Developer 3 to be part of making this happen. About the Role You’ll work on the software stack that runs inside Arctic Wolf’s network sensors — physical appliances and virtual sensors deployed across customer environments. The team owns everything from the on-sensor Go services and Python tooling, to the AWS infrastructure that manages, monitors, and upgrades sensors at scale. You’ll write code that ships inside customer networks, runs 24/7 without human intervention, and needs to be correct the first time. What You’ll Do • Build and maintain on-sensor Go and Python services — daemons, config managers, upgrade pipelines, and tunneling infrastructure • Own AWS infrastructure used for sensor management: ECS services, CloudFormation stacks, EC2 instances, S3 artifact pipelines, and CloudWatch observability • Improve and extend the CI/CD platform: Jenkins pipelines, Docker build environments, Robot Framework cell tests that spin up virtual sensors on AWS/Azure/VMware and validate end-to-end behaviour • Debug hard problems: kernel networking (eBPF/XDP, Suricata, iptables), multi-platform VM orchestration, Ansible-based sensor provisioning, and production incidents traced through CloudWatch Logs Insights • Contribute to sensor upgrade and deployment automation (Ansible, Debian packaging, manifest-driven rollouts) • Work across the full stack — from BPF maps pinned on a sensor’s kernel to ECS services in AWS serving REST APIs to the portal What We’re Looking For • 3–5 years of professional software development experience • Strong AWS hands-on experience: EC2, ECS (Fargate + EC2 launch types), S3, CloudWatch (Logs, Metrics, Alarms), CloudFormation or CDK, IAM • Proficiency in Python — writing production services, CLI tooling, and test automation (Robot Framework or pytest) • Comfort with Linux systems programming: systemd, networking (iptables, interfaces, routing), Debian packaging, shell scripting • Experience with CI/CD pipelines (Jenkins, GitHub Actions, or equivalent) and Docker-based build environments • Strong debugging skills — able to trace a production problem from a CloudWatch log through to a root cause in code Nice to Have • Ansible for fleet configuration and provisioning • Networking depth: VLANs, SPAN/TAP modes, DHCP, tunneling protocols (FRP, WireGuard) • eBPF/XDP or kernel networking (Suricata, nmap, packet capture) • Experience with VMware, Hyper-V, or Azure for infrastructure testing • Familiarity with sensor/appliance software or embedded Linux Our Values Arctic Wolf recognizes that success comes from delighting our customers, so we work together to ensure that happens every day. We believe in diversity and inclusion, and truly value the unique qualities and unique perspectives all employees bring to the organization. And we appreciate that—by protecting people’s and organizations’ sensitive data and seeking to end cyber risk— we get to work in an industry that is fundamental to the greater good.
