The posting

Why join us Tractian is transforming the industrial world by empowering frontline maintenance workers to achieve more. We’ve fused cutting-edge hardware with innovative software into one powerful platform, disrupting legacy systems and delivering smarter, faster solutions for our clients.

AI Engineering at Tractian The AI Engineering team at Tractian focuses on extracting actionable intelligence from vast amounts of industrial assets, telemetry, and maintenance workflows. We bridge the gap between state-of-the-art machine learning models and mission-critical industrial applications. By bringing rigorous software engineering principles to modern AI, we build scalable, event-driven, and resilient systems that frontline engineers rely on 24/7, directly optimizing frontline productivity and asset reliability.

What you'll do We're seeking a Senior AI Engineer with a solid software engineering foundation to design, develop, and deploy production-ready AI and agentic systems. In this role, you will bring strong product vision and high agency, proactively exploring the problem space and driving technical solutions end-to-end. You'll build robust APIs, architect event-driven data streaming pipelines, implement intelligent information retrieval systems, and orchestrate custom agentic workflows that connect AI capabilities with real-world industrial applications.

Responsibilities Design and develop production-grade applications and custom agentic workflows powered by LLMs. Build intelligent data processing workflows using OCR, PDF layout analysis, audio and image models. Architect and scale event-driven data streaming pipelines using Apache Kafka to power AI workloads. Create and maintain high-performance APIs that integrate AI capabilities with our platform. Implement evaluation frameworks (evals) to benchmark and track model quality, accuracy, and regressions. Partner proactively with product teams to define technical requirements. Mentor engineers, drive architecture discussions, and ensure best practices through code reviews.

Requirements 5+ years of experience in software engineering with a strong backend/distributed systems foundation. 2+ years of experience building and shipping production AI/LLM systems. Bachelor's degree in Computer Science, Engineering, Information Systems, or equivalent technical field. Demonstrated experience building production-grade applications with custom agentic systems, document processing pipelines, and/or information-retrieval systems. Hands-on experience with event-driven architectures and streaming using Apache Kafka. Working knowledge of AI evaluation methods (evals), observability/tracing, security guardrails, cost optimization, latency reduction, and semantic caching. Strong proficiency in Python and/or Golang, with experience in frameworks like FastAPI or Flask. Strong proficiency in designing, building, and maintaining production REST APIs and databases. High ownership and strong product sense: able to take ambiguous problems, collect technical requirements, prioritize impact, and execute independently.

Preferred Qualifications Experience with LLM fine-tuning and model optimization techniques. Knowledge of containerization (Docker, Kubernetes) and microservices architecture.

Technical Skills Programming: Python and/or Golang. Frameworks: FastAPI, Flask. Agentic Systems: Custom state machines, tool-calling pipelines, execution loops. Streaming & Messaging: Apache Kafka, event-driven architecture. Document Processing: OCR engines, PDF parsing, multimodal LLMs. AI Reliability: Evals (LLM-as-a-judge, benchmarks), observability, tracing, guardrails. API Development: REST, OpenAPI, gRPC. Databases: PostgreSQL, Redis, vector databases. LLM Integration: OpenAI, Anthropic, and open-source models.

Compensation & Benefits Competitive Compensation 30 days of paid annual leave Education and courses stipend Earn a trip anywhere in the world every 4 years R$1.035/month for meals allowance Health plan with national coverage and without coparticipation Dental Insurance: we help you with dental treatment for a better quality of life.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
