Fractional Engineer Software information

What is a fractional engineer software?

A Fractional Engineer Software is a software engineer who works with companies on a part-time or contract basis, providing specialized technical expertise without the commitment of a full-time role. This arrangement allows organizations to access high-level engineering skills and experience for specific projects or periods of growth, often at a lower cost than hiring a full-time employee. Fractional engineers may assist with architecture, code reviews, team leadership, or scaling technology, adapting their involvement based on the company's evolving needs.

What are the key skills and qualifications needed to thrive as a fractional engineer software, and why are they important?

To thrive as a Fractional Engineer Software, you need a robust background in software development, problem-solving, and experience with multiple programming languages, often supported by a degree in computer science or related field. Familiarity with cloud platforms, version control systems like Git, and agile development tools is typically required. Strong communication, adaptability, and self-management skills are essential for integrating quickly with diverse teams and projects. These skills ensure effective contribution, flexibility, and value delivery across various client engagements.

How does a fractional engineer software typically integrate with existing development teams, and what are the expectations for collaboration?

Fractional software engineers often join established teams on a part-time or project basis, so they are expected to quickly adapt to existing workflows and communication tools. Effective collaboration is key, and fractional engineers are usually included in daily stand-ups, sprint planning, and code reviews, even if asynchronously. They are valued for their ability to bring fresh perspectives while respecting established processes, and clear documentation of their work helps ensure seamless handoffs. Building strong relationships with full-time staff and maintaining open communication are essential for success in this flexible role.

Job description

All key offline workloads — large-scale data processing, simulation, auto-labeling, scenario mining, and model training — run on the compute platform this role owns. In this role, you will improve the reliability and efficiency of our Kubernetes infrastructure, make workload onboarding simpler and more self-service, and build reusable batch and workflow capabilities for petabyte-scale processing. We are looking for strong Kubernetes and platform-engineering fundamentals, depth in at least one adjacent area—distributed data processing, ML/GPU infrastructure, or multi-tenant compute systems—and the curiosity and ownership to grow across the others.


We are open to candidates at either the Software Engineer or Senior Software Engineer level. Level will be determined by experience, technical depth, scope of ownership, and demonstrated impact. You do not need experience with every technology in our stack; we value strong fundamentals, ownership, and the ability to learn.


Responsibilities:

  • Operate and evolve our production Kubernetes clusters end to end: bare-metal provisioning automation, highly available control planes, node lifecycle, GPU container runtime, networking, and storage

  • Build safe, repeatable GitOps-based delivery for platform services and user applications using tools such as Argo CD, Helm, and Kustomize

  • Develop shared multi-tenant platform capabilities for scheduling, resource isolation, storage, networking, access control, secrets, and observability while improving CPU/GPU utilization and cost efficiency

  • Build and improve reusable distributed batch and workflow platforms for Spark data processing and GPU-based replay and simulation

  • Ensure that your work is performed in accordance with the company’s Quality Management System (QMS) requirements and contribute to continuous improvement efforts

Required Skills:

  • BS, MS, or PhD in Computer Science or a related technical field, or equivalent practical experience

  • Hands-on experience operating production Kubernetes clusters — node lifecycle, upgrades, troubleshooting — plus GitOps and infrastructure-as-code experience

  • Experience with GPU or ML workload scheduling, queueing and priorities, fractional GPU sharing, autoscaling, or multi-tenant resource management

  • Self-driven with a strong sense of ownership: a quick learner who is eager to take responsibility and drive projects forward end to end

Preferred Skills:

  • Experience with Ray or Kubeflow

  • Experience with lakehouse technologies such as Delta Lake or Apache Iceberg

  • Experience operating large-scale distributed data-processing and workflow systems, with hands-on depth in a system such as Apache Spark and working knowledge of Argo Workflows or an equivalent orchestrator

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
