WHO WE ARE LOOKING FOR?

We are seeking a highly skilled Linux Engineer to join our team, working on our innovative edge computing platform. As part of a cross-functional DevOps group, your primary focus will be managing on-premise edge infrastructure, ensuring the reliability of containerized applications, and designing and implementing CI/CD pipelines, while also extending some workloads to AWS as needed (but not required).

The platform currently runs on NVIDIA Jetson Orin and Raspberry Pi 5 devices. We are expanding our supported hardware line, so a core part of this role is researching and evaluating new edge-compute hardware candidates and porting or adapting the platform to run on them — working closely with hardware vendors, product, and engineering stakeholders to make build-vs-buy and platform-fit decisions.
 

KEY RESPONSIBILITIES

1. On-Premise Infrastructure Provisioning & Configuration Management

• Use Ansible to automate the configuration and deployment of servers, networking, and storage.

2. Hardware Platform Research & Enablement (New)

• Assess and score candidate hardware against a standard set of criteria — compute/GPU capability, expansion options (storage, ethernet, PCIe/M.2, wireless/LTE), carrier board availability, cost, vendor relationship and supply chain risk, architecture (ARM vs. x86), target vertical fit, and third-party licensing constraints.
• Port and adapt the platform to new hardware targets, including OS/kernel bring-up, driver and peripheral enablement, and validation of Nomad/Consul/Ansible workflows on the new devices.

3. Container Orchestration & Deployment

• Use HashiCorp Nomad to deploy and scale containerized applications on on-premise edge nodes.

4. Distributed Storage & Data Management

• Work with a distributed file system (SeaweedFS) to ensure high availability, replication, and fault tolerance.
• Implement best practices for data redundancy, security, and efficient data access.

5. CI/CD Pipeline Development

• Design, implement, and maintain robust GitLab CI/CD pipelines for containerized applications.
• Continuously refine automation workflows for software build, test, and deployment stages.

6. Collaboration & Communication

• Work alongside existing infrastructure, DevOps, and Developer teams to identify areas of process improvement and lead automation initiatives.
   

WHAT YOU BRING ALONG

• Upper-Intermediate English level.
• 10+ years of experience in DevOps, SRE, or infrastructure engineering roles, with a track record of end-to-end project delivery.
• Expert knowledge of Linux systems administration (networking, security, and performance tuning).
• Networking expertise: extensive experience with VPN, SDN, mDNS, and related tools for secure, resilient communication in distributed environments.
• Configuration management experience with Ansible.
• Strong scripting skills in Bash and Python for automation tasks.
• Working knowledge of embedded/single-board and edge-compute hardware (e.g., NVIDIA Jetson, Raspberry Pi) — CPU/GPU/memory sizing, storage and networking expansion, and peripheral bring-up.
• Comfort evaluating hardware across different architectures (ARM, x86) and reasoning about the portability impact of an architecture change.
• Basic understanding of hardware sourcing considerations: carrier board ecosystems, unit/BOM cost trade-offs, vendor relationships, and supply chain risk.
• Hands-on experience with containerization tools (Docker) and orchestration platforms (HashiCorp Nomad preferred, or Kubernetes).
• Practical experience with HashiCorp Consul for service discovery and configuration management, particularly in conjunction with Nomad-based deployments.
• Proven ability to design and implement CI/CD pipelines using tools such as GitLab CI (preferred), Jenkins, or GitHub Actions.
• Familiarity with distributed storage (SeaweedFS preferred, Ceph) and replication strategies for high availability and data redundancy.
• Experience setting up and deploying relational databases (PostgreSQL and cluster configuration for high availability and scalability preferred).
• Ability to work in a hybrid environment: on-site for hardware setup and troubleshooting when needed, and remote for the majority of development work.
• Bachelor's or Master's degree in Computer Science, Information Technology, or a related field.
   

WILL BE A PLUS

• Networking expertise: Nebula for secure peer-to-peer communication or any other SDN.
• Experience with monitoring and logging tools (e.g., Prometheus, Grafana, ELK) for performance tracking and alerting at scale.
• Prior hands-on hardware evaluation/selection experience, e.g., benchmarking or qualifying new edge-compute boards for a product line.
• Experience with board bring-up or board support package (BSP) integration on embedded Linux devices.
• MLOps knowledge, including model deployment and lifecycle management at scale.
• IoT experience, particularly in device management, data ingestion, and security considerations.
