About the Team:

Dark Matter Lab is a research group within Relativity Space focused on advanced aerospace systems, agentic engineering, and technologies outside the conventional roadmap. We build the infrastructure needed to turn new ideas into engineering capabilities people can actually depend on.

About the Role:

We run a stack of interconnected agentic systems — SybilClaw, yapCAD, Mechatron, Multigraph, local LLM inference, an inter\-agent message bus, parametric CAD pipelines, a print farm, and the infrastructure connecting it all. We need an engineer who can own and evolve these systems as they move from prototypes into production engineering infrastructure.

This role is for someone who has deployed an agentic harness (OpenClaw, Hermes, SybilClaw, or something comparable) in a real work environment. You understand what it takes to make these systems reliable when engineers depend on them every day. You'll learn the stack, improve it, and work with forward\-deployed engineers to package portions of it for deployment with internal and external customers.

  • Own the reliability of our agentic infrastructure: agents, sessions, model routing, context pipelines, inter\-agent communication, and supporting services
  • Build and maintain infrastructure where good off\-the\-shelf solutions don't yet exist
  • Deploy and operate local LLM inference across Mac Studio and GPU hardware
  • Manage Linux/macOS systems, Proxmox VMs and containers, storage, backups, and recovery
  • Maintain multi\-site networking including L3 routing, VLANs, DNS, firewalls, and connectivity
  • Build CLIs, dashboards, automation, and internal tools that make engineers faster
  • Improve observability, debugging, and automated failure recovery
  • Contribute upstream to open\-source projects we rely on
  • Help design practical security around local compute, data handling, and access controls
  • Package and deploy portions of the stack into internal and customer environments
  • Work directly with engineers to understand what they need and turn recurring problems into better infrastructure

About You:

  • 5\+ years of experience building and operating complex software and compute infrastructure, with hands\-on work across hardware, operating systems, networking, and automation
  • Experience deploying an agentic harness such as OpenClaw, Hermes, SybilClaw, or a comparable system in a real work environment
  • Strong Linux and macOS systems experience, including debugging services, processes, storage, permissions, and networking
  • Experience operating physical infrastructure, VMs, or containers in production
  • Strong networking fundamentals including routing, VLANs, DNS, and firewalls
  • Ability to build software, scripts, CLIs, and integrations when existing tools aren't sufficient
  • Meaningful experience contributing to or maintaining open\-source software
  • Strong judgment around reliability, security, performance, and simplicity

Nice to haves but not required:

  • Experience with ITAR\-regulated, air\-gapped, export\-controlled, or similarly constrained environments
  • Experience operating local LLM inference with Ollama, MLX, vLLM, llama.cpp, or similar
  • Experience with model routing, context management, tool execution, agent state, or multi\-agent systems
  • Experience building internal developer infrastructure used daily by other engineers
  • Experience deploying systems into customer or forward\-deployed environments
  • A GitHub, Gitea, or other body of work where we can see what you've built

*This role requires in\-office presence at least three days per week, with flexibility to work remotely when the work allows. Much of this infrastructure is physical, local\-first, and best built alongside the engineers using it.*

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.

*If you need a reasonable accommodation, please contact us at* *[email protected]**.*

*Please note: Relativity Space does not accept unsolicited resumes, candidate profiles, or referrals from recruitment agencies or search firms. Any unsolicited submission \- via email, our website, social media, or directly to an employee \- will be deemed the property of Relativity Space, and no fee will be owed absent a current, fully executed agreement with Talent Acquisition that specifically authorizes submissions for the applicable role.*

About This Role

AI/ML Engineers build and deploy machine learning models in production. They work across the full ML lifecycle: data pipelines, model training, evaluation, and serving infrastructure. The role has evolved significantly over the past two years. Where ML Engineers once spent most of their time on model architecture, the job now tilts heavily toward inference optimization, cost management, and integrating LLM capabilities into existing systems. Companies want engineers who can ship production systems, and the experimenter-only role is fading fast.

Day-to-day, you're writing training pipelines, debugging data quality issues, setting up evaluation frameworks, and figuring out why your model performs differently in staging than it did on your dev set. The best ML engineers are obsessive about reproducibility and measurement. They instrument everything. They know that a model is only as good as the data feeding it and the infrastructure serving it.

Across the 4,317 AI roles we're tracking, AI/ML Engineer positions make up 70% of the market. At Relativity Space, this role fits into their broader AI and engineering organization.

Demand for AI/ML Engineers has been strong and consistent. Unlike some AI roles that spike with hype cycles, ML engineering is a foundational need. Every company deploying AI models needs people who can keep them running, and the gap between research prototypes and production systems keeps growing.

What the Work Looks Like

A typical week might include: debugging a data pipeline that's silently dropping 3% of training examples, running A/B tests on a new model version, writing documentation for a feature flag system that lets you roll back model deployments, and reviewing a junior engineer's PR for a new evaluation metric. Meetings tend to be cross-functional since ML touches product, engineering, and data teams.

Skills Required

Llama (2% of roles)

Python and PyTorch dominate the requirements. Most roles expect experience with cloud platforms (AWS, GCP, or Azure) and familiarity with ML frameworks like TensorFlow or JAX. RAG (Retrieval-Augmented Generation) has become a top-3 skill requirement as companies integrate LLMs into their products. Docker and Kubernetes show up in about a third of postings, reflecting the production focus of the role.

Beyond the core stack, employers increasingly want experience with experiment tracking tools (MLflow, Weights & Biases), feature stores, and vector databases. Fine-tuning experience is valuable but less common than you'd think from reading Twitter. Most production LLM work is RAG and prompt engineering, not fine-tuning. If you have both, you're in a strong position.

Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.

Career Path

Common paths into AI/ML Engineer roles include Data Scientist, Software Engineer, Research Engineer.

From here, career progression typically leads toward ML Architect, AI Engineering Manager, Principal ML Engineer.

The fastest path into ML engineering is through software engineering with a self-directed ML education. A CS degree helps, but production engineering skills matter more than academic credentials. Build something that works, deploy it, and measure it. That portfolio project is worth more than a Coursera certificate. For career growth, the fork comes around the senior level: go deep on technical complexity (staff/principal track) or move into managing ML teams.

What to Expect in Interviews

Expect system design questions around ML pipelines: how you'd build a training pipeline for a specific use case, handle data drift, or design A/B testing infrastructure for model deployments. Coding rounds typically involve Python, with emphasis on data manipulation (pandas, numpy) and algorithm implementation. Take-home assignments often ask you to build an end-to-end ML pipeline from raw data to deployed model.

When evaluating opportunities: Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.
