About This Role

AI job market dashboard showing open roles by category

Palona’s AI agents operate in real restaurant environments: noisy phone lines, varied accents, complex menus, interruptions, incomplete information, strict business rules, and customers who expect an immediate, natural response. Improving these systems requires more than selecting the newest model. It requires disciplined evaluation, high\-quality data, modeling judgment, experimentation, and production feedback loops.

We are looking for an applied AI Modeling Engineer to improve the intelligence, accuracy, safety, latency, and cost of Palona’s voice and multimodal agents. You will own problems across model selection and routing, prompting and context, fine\-tuning or post\-training when justified, speech and language quality, evaluation methodology, dataset development, and model behavior in production.

This is a product\-facing modeling role. Research depth matters, but success is measured by improvements that survive contact with production and create better guest, restaurant, and business outcomes. You will work closely with product, full\-stack, infrastructure, and customer\-facing engineers to move from hypothesis to experiment to reliable deployment.

What you’ll own* Develop modeling and experimentation strategies for high\-impact agent problems in voice, language, reasoning, ordering, multilingual behavior, and multimodal understanding.

  • Build rigorous offline and online evaluations that measure task completion, accuracy, safety, latency, cost, conversational quality, and business outcomes.
  • Create and maintain representative datasets from simulations, human annotation, production feedback, and difficult edge cases while protecting sensitive data.
  • Evaluate frontier and open\-source models and make clear build, buy, route, prompt, fine\-tune, or distill decisions.
  • Improve prompting, context construction, memory, tool\-use policies, structured outputs, model routing, and fallback behavior.
  • Design fine\-tuning, preference optimization, distillation, or other post\-training work when it offers a measurable advantage over simpler methods.
  • Partner with speech and real\-time engineers to improve ASR, TTS, turn\-taking, interruption handling, pronunciation, multilingual behavior, and end\-to\-end latency.
  • Develop analysis tools that explain model failures, slice performance by scenario, detect regressions, and accelerate iteration.
  • Ship model changes with production guardrails, staged rollouts, monitoring, rollback paths, and clear quality gates.
  • Translate new research and model releases into concrete product opportunities and communicate tradeoffs to technical and non\-technical partners.
  • Raise scientific and engineering standards through reproducible experiments, thoughtful reviews, and clear documentation.

Requirements

  • 3\+ years of industrial experience in relevant technical domain.
  • Strong machine learning foundations and hands\-on experience developing or evaluating production AI systems.
  • Strong Python skills and experience with modern ML tooling such as PyTorch, JAX, Hugging Face, or equivalent systems.
  • Practical experience with LLMs, speech models, multimodal models, or agentic systems.
  • Ability to design reliable experiments, define useful metrics, analyze noisy results, and avoid optimizing against weak proxies.
  • Experience building datasets, evaluation harnesses, model services, or training and inference pipelines.
  • Strong software engineering judgment; your work is reproducible, tested, observable, and usable by other engineers.
  • Ability to connect modeling choices to product constraints including latency, cost, privacy, safety, and user experience.
  • Comfort operating in ambiguity and collaborating across research, engineering, product, and customer contexts.
  • AI\-native working habits and genuine curiosity about new model capabilities and limitations.

Benefits

  • Competitive Salary and Stock Option Plan.
  • Medical, dental, vision, retirement, leave, and disability benefits as applicable.
  • Family Leave
  • Short Term \& Long Term Disability
  • Paid time off and company holidays.
  • Learning and development support.

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 Palona AI, 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

Hugging Face (3% of roles) Jax (2% of roles) Python (52% of roles) Pytorch (15% 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.
