Get Access To All JobsTitle: Sr. RHEL Designer/Engineer (OT/SCADA)
Location: preference for Houston, TX or in Miami, FL, Houston, TX or Reston, VA
Term: Full Time, Direct Hire – remote but may need to travel to client locations periodically, especially at the start or kick off of a project.
Position Overview
Our client delivers turnkey clean energy and power infrastructure solutions across the Americas. We design, build, and operate advanced Battery Energy Storage Systems (BESS) and mission-critical networks for data centers, utilities, and industrial clients. Our technology-first mindset powers systems from SCADA to cloud—and everything in between.
About The Position
The Senior RHEL engineer will own the OS and container platform behind our on-premises energy-management deployments. You'll build and harden the tailored RHEL image and the containerized Ignition SCADA workload running on industrial PCs across U.S. data-center sites, and act as our deep RHEL authority and L3 escalation point. This is a platform-engineering and expertise role — not field installation.
You will own our OS architectures, container builds and configuration, and the runtime that hosts Ignition, while the SCADA team owns everything configured inside Ignition (tags, screens, logic). On the network side, the host firewall and OS-level networking (interfaces, routing, DNS, firewalld/nftables) are yours, while the physical and site network beyond the host NIC belongs to Operational Technology (OT).
Travel to third-party data-center sites is for troubleshooting and support only. The separate OT team commissions and deploys every machine, so you won't install systems in the field.
Responsibilities:
- Build, version, and maintain a reproducible, turnkey RHEL image tailored to the SCADA host's needs (time sync, firewall/ports, storage, service ordering, resource tuning).
- Own the SCADA container image end to end: Containerfile, base image, JVM, persistence, ports, hardening, scanning, and registry.
- Run containers as systemd services via Podman and quadlets.
- Harden the OS and images to a recognized baseline (CIS/STIG) and define a patching and lifecycle strategy for OT uptime and restricted/disconnected sites (offline/mirrored registry).
- Troubleshoot full-stack — OS, container runtime, and application runtime behavior — remotely and on-site, handing off application-level issues to the SCADA team.
- Own host-level networking and firewall configuration (interfaces, routing, DNS, firewalld/nftables, and port exposure for the SCADA container), and lead connectivity troubleshooting between the host and site infrastructure.
- Document runbooks for the OT team and help define the connectivity and security posture.
- Maintain the Windows image pipeline (Packer-based) in steady state once established: periodic patching, hardening updates, and image rebuilds.
Qualifications
- 7+ years of senior, hands-on production RHEL/Linux engineering.
- Container-native delivery: Podman, quadlets/systemd, building and owning container images (including packaging a JVM-based app such as Ignition), and registry management.
- Reproducible, turnkey, versioned RHEL image building (bootc, Kickstart, Image Builder/osbuild, or Ansible-driven).
- OS and image hardening to a recognized baseline (CIS/STIG).
- Patch and lifecycle management for restricted/disconnected environments, including offline/mirrored content and registries.
- Automation (Ansible) and version control.
- Strong Linux networking and diagnostics: firewall administration (firewalld/nftables) and packet/connectivity tooling (Wireshark, tcpdump, ss, ip), plus containerized debug environments (toolbox).
- Confidence operating as the RHEL authority, with strong documentation habits.

Target roles that align with H-1B specialty occupation standards
Ascending sponsors within technology and software, so roles requiring a specific degree in computer science, engineering, or a related field are your strongest bet. Applying for positions with clear degree requirements improves your chances of sponsorship approval.
Highlight OPT status early if you're an F-1 student
Ascending has sponsored F-1 OPT candidates, making it worth flagging your work authorization upfront in your application. Recruiters move faster when they know your current status and remaining OPT timeline without having to ask.
Understand TN eligibility if you're Canadian or Mexican
Ascending also sponsors TN visas, which require less lead time than H-1B and have no lottery. If you qualify under a TN-eligible occupation in technology, lead with that in conversations, it simplifies the sponsorship conversation significantly.
Use Migrate Mate to confirm Ascending's current open roles
Sponsorship willingness only matters if there's a role to apply for. Migrate Mate surfaces verified sponsors so you can filter by real sponsorship history and find Ascending's active listings without guessing which postings are open to visa candidates.
Prepare for technical interviews that reflect the software industry
Ascending operates in technology and software, so expect technical assessments alongside standard interviews. Demonstrating strong domain expertise signals you're worth the additional effort and cost a sponsorship involves for a smaller-volume sponsor.
Reach out to hiring managers directly for sponsored roles
For companies with focused sponsorship activity, timing matters. Connecting with a hiring manager or recruiter at Ascending before a role fills can position you ahead of other applicants and open a direct conversation about visa sponsorship needs.
Frequently Asked Questions
Does Ascending sponsor H-1B visas?
Yes, Ascending sponsors H-1B visas for qualifying roles in technology and software. H-1B sponsorship requires the position to meet specialty occupation standards, meaning a specific bachelor's degree or higher in a related field is typically required. Given Ascending's focused sponsorship activity, it's worth applying early and being transparent about your visa needs from the first conversation.
Which visa types does Ascending sponsor?
Ascending sponsors H-1B visas, F-1 OPT extensions, and TN visas. This range covers a broad set of international candidates, from recent graduates on OPT to experienced professionals eligible for the TN category. If you're Canadian or Mexican and work in a qualifying technology occupation, the TN pathway through Ascending is particularly worth exploring given its simpler processing requirements.
What types of roles at Ascending are most likely to receive visa sponsorship?
Sponsorship at Ascending is concentrated in technology and software functions, where roles typically require specialized degrees and technical expertise, the foundation of H-1B specialty occupation eligibility. Engineering, software development, and related technical positions are the most natural fit. Roles that are generalist in nature or don't require a specific degree field are less likely to be sponsored.
How do I find open visa-sponsored jobs at Ascending?
Migrate Mate is the most reliable way to find Ascending's open roles that include visa sponsorship. The platform verifies sponsorship history so you're not applying blind to postings that may not support international candidates. Filtering by company and visa type lets you focus your effort on positions where sponsorship is already confirmed rather than having to ask at each stage.
How do I improve my chances of getting sponsored by Ascending?
Apply to roles where your degree field directly matches the position, this is the single biggest factor in H-1B specialty occupation approvals. Be upfront about your visa status and timeline early in the process so Ascending's team can plan accordingly. If you're on OPT, communicate your STEM extension eligibility if applicable, as it extends the window for employers and reduces urgency around H-1B filing deadlines.
