About This Role

AI job market dashboard showing open roles by category

Figure is an AI Robotics company developing a general purpose humanoid. Our humanoid robot is designed for commercial tasks and the home. We are based in San Jose and require 5 days/week in\-office collaboration. It’s time to build.

We're looking for a senior\-level backend engineer who has scaled high\-throughput, low\-latency data systems and has strong instincts around cloud infrastructure and real\-time streaming pipelines. You'll architect and build the core backend systems that power Figure's real\-time data infrastructure — enabling the scale and reliability that our AI and robotics platforms depend on.

This is a high\-ownership role at the intersection of media and sensor data streaming, cloud systems, and applied ML serving. You'll work closely with our AI and robotics teams to ensure latency, reliability, and throughput meet the demands of real\-world robot operation.

WHAT YOU'LL DO

  • Architect and scale cloud backend infrastructure for high\-concurrency, real\-time streaming of media and sensor data across robot fleets and user sessions.
  • Design and build low\-latency data pipelines that ingest, route, and process high\-bandwidth streams — including camera feeds, IMU data, and other robot sensor outputs — into our AI stack in real time.
  • Own reliability, latency, and throughput SLAs for streaming and data infrastructure.
  • Collaborate with AI and robotics teams to integrate ML model serving into real\-time data pipelines.
  • Build observability, alerting, and tooling to give the team full situational awareness over live robot traffic.
  • Drive architectural decisions and mentor engineers across the team.

WHAT WE'RE LOOKING FOR

  • Deep experience scaling cloud backend systems handling high\-concurrency, real\-time data streams — media, sensor, telemetry, or equivalent high\-bandwidth pipelines.
  • Strong fundamentals in distributed systems: stream processing, connection management, data transport, and low\-latency architecture.
  • Proficiency in one or more backend languages (Go, C\+\+, Python, Rust) and cloud platforms (AWS, GCP, or Azure).
  • Experience with containerized infrastructure, service mesh, and large\-scale deployment pipelines.
  • Strong communication and cross\-functional collaboration skills.

NICE TO HAVE

  • Hands\-on experience integrating AI inference serving (Triton Inference Server, TensorRT, SageMaker, or similar) into real\-time data pipelines.
  • Background in robotics, autonomous vehicles, live media platforms, or other latency\-critical streaming domains.
  • Familiarity with protocols such as WebRTC, RTSP, gRPC, or Kafka for real\-time data transport.
  • Experience with on\-device or edge inference and the tradeoffs of cloud vs. edge processing.

The US base salary range for this full\-time position is between $150,000 \- $400,000 annually.

The pay offered for this position may vary based on several individual factors, including job\-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.

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 3,824 AI roles we're tracking, AI/ML Engineer positions make up 71% of the market. At figure, 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

Aws (31% of roles) Azure (23% of roles) Gcp (19% of roles) Python (51% of roles) Rust (1% of roles) Sagemaker (5% 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.
