Senior AI/ML Engineer (GenAI, AWS)

Requirements:

Mindset

• Proactive and self-directed; you push for clarity rather than waiting for a ticket

• Excellent communication and problem-solving skills

• Comfort with ambiguity and ownership.

• B2+ English, comfortable collaborating across distributed, multicultural teams.

Technical depth

• 5+ years in software or ML engineering, with production systems you were accountable for.

• Solid AI/ML foundations. You understand what the models do well enough to reason about failure modes.

• Shipped to production LLM applications and agentic workflows — not demos, not POCs, not notebooks.

• Agentic orchestration: multi-step workflows, graph-based orchestration, tool use, state management, and recovery from partial failure

• Experience with LLM APIs (Anthropic, AWS Bedrock, or OpenAI) and agent frameworks.

• Experience building and optimizing RAG systems in production.

• Strong engineering fundamentals. Full-stack mindset, comfortable across AI, backend development, and cloud infrastructure. Python and/or TypeScript proficiency; depth matters more than stack. Dropped into an unfamiliar codebase, you're productive.

• Hands-on AWS in production: Bedrock, Bedrock AgentCore, Lambda, ECS, S3, SQS, ECR, or similar. GCP or Azure is a plus.

• Cloud-native delivery: containers, ECS or Kubernetes, IaC, and CI/CD applied to AI pipelines.

• You evaluate. You have built or owned an eval suite for a non-deterministic system, and you can explain what you measured, how you produced ground truth, and what gated a release.

• Model and agent monitoring, drift detection.

• Cost and latency discipline: model tiering, caching, and the ability to say what a workload costs to run before it runs.

• Hands-on production experience with the Claude ecosystem — Claude Code, CLAUDE.md, hooks, skills files. Spec-driven development — writing the intent, constraints, and acceptance criteria before you let an agent build — is a strong plus.

• MCP: you can say why an agent would prefer it to a REST integration. Having authored a server is a plus.

Nice to Have:

• Experience in one of the industries: financial services, insurance, healthcare.

• Consulting, professional services, or other embedded customer-facing delivery.

• AWS and Claude Code Certifications

• A2A: you can explain agent-to-agent interoperability

• CI/CD pipeline experience (GitHub Actions, GitLab CI)

• Practical experience with one or more use cases from the following: NLP, LLMs, and Recommendation engines.

• Experience in an additional language (Go, TypeScript, or Rust).

• Experience with Apache Spark, Apache Airflow, Kafkа

Responsibilities:

• Work in a pair with an FDE and an FDX.

• Build and ship production GenAI systems into the customer’s environment (cloud-native data, LLM-based, and agentic AI solutions).

• Build and optimize RAG systems for production use cases

• Build the evaluation harness before you build the feature.

• Write production code across the stack — AI, backend services, data pipelines. We choose tools to fit the customer.

• Integrate AI components into backend services and RESTful APIs

• Take systems to production on AWS (GCP or Azure where the customer requires it): containerised, CI/CD. Implement LLMOps and AgentOps practices: agent tracing, prompt and version management, cost and latency monitoring, regression testing, drift detection

• Start from the blueprint, contribute to enablement and handover: clear documentation, runbooks, and pairing with the client engineers who will inherit the system. Feed reusable components and lessons back into the Provectus Blueprints

• Participate in technical discussions and architectural decisions

• Conduct model evaluation, improve failure modes you find, optimize model performance, efficiency, and reliability

• Mentor junior and mid-level AI engineers, conduct code reviews and share knowledge across the team through documentation, presentations, and workshops.

What We Offer:

The chance to shape how leading enterprises across LATAM, Europe, and North America adopt AI, from strategy through first deployment

A forward-deployed model working in small, senior teams alongside FDE and FDX

A growing AI delivery practice where you help build the tooling and frameworks, not just use them

Remote-friendly culture
