Sr Principal Software Engineer: AI Systems

Description

:

Be a technical pillar for the SuperAgent ecosystem. This is a high-leverage role for a strong Full Stack Engineer who thrives at the intersection of complex systems architecture and cutting-edge AI.

You will architect the infrastructure that allows AI agents to reason, plan, and execute across massive EDA datasets.

You will bridge the gap between cloud-scale innovation and the stringent security requirements of on-premises semiconductor environments.

You will be a lead contributor to our core agentic frameworks, ensuring they are modular, observable, and production-ready.

Full-Stack Ownership: Drive end-to-end development using Python (for LLM orchestration and data logic) and TypeScript/React (for sophisticated agent-human interaction interfaces).

Hybrid Deployment Strategy: Design systems that are equally performant in modern Cloud environments and secure, air-gapped On-Premise data centers.

​ Evaluation & Reliability: Build "LLM-native" CI/CD pipelines, including automated red-teaming, regression testing for agent trajectories, and sophisticated observability to monitor agent "drift."

Technical Leadership: Mentor senior and mid-level engineers, define engineering best practices, and influence the long-term technical roadmap for AI-driven verification.

Requirements: Complete Bachelor's degree in Computer Science, Electrical/Electronic Engineering,etc.

Experience: 10+ years of professional software development experience, with a track record of leading complex, distributed systems projects.

The Stack: Deep proficiency in Python and TypeScript. You should be comfortable moving from a low-level data pipeline to a high-level frontend component.

Cloud & On-Prem: Proven experience deploying and scaling enterprise-grade software across diverse environments (AWS/Azure/GCP and Kubernetes-based on-prem clusters).

Engineering Fundamentals: Mastery of system design, API contract versioning, and refactoring legacy complexity into clean, testable abstractions.

Strong verbal and written communication skills in English and Portuguese.

Nice to have: Agentic Frameworks: Hands-on experience with frameworks to build agents (e.g., Agents SDK from leading LLM labs).

LLM Engineering: Experience with prompt optimization, structured output generation (Pydantic/instructor), and managing context windows for long-running engineering tasks.

Retrieval Systems: Deep understanding of RAG pipelines, including hybrid search, vector databases (Milvus, Pinecone, or pgvector), and advanced chunking strategies for technical documentation.

EDA Interest: While prior semiconductor experience isn't required, a passion for high-performance computing and how silicon is built is a huge plus.

Additional Job Details: Employment category: CLT.

Employment term:40 hours/week.

Competitive benefits.
