Job Description

The Knowledge Assist (KA) team at Cresta builds AI solutions that help contact center agents access the right knowledge at the right time. Our projects include real-time generative assistance (GenKA), knowledge search (KS), retrieval-augmented generation (RAG) capabilities, and knowledge connectors to integrate with customer systems. We are looking for a software engineer who enjoys working across the stack and thrives in a dynamic, fast-paced environment. While this role leans toward backend development, a full stack skill set is highly valued.

Job Responsibility

  • Build scalable, reliable backend services that power real-time AI assistance and search
  • Design APIs and data flows to support integrations with knowledge bases and customer systems
  • Work across the stack when needed, including backend, frontend, and infrastructure layers
  • Collaborate closely with product managers, machine learning engineers, and fellow software engineers
  • Take ownership of projects end-to-end, from design through implementation and operation in production
  • Contribute to technical discussions, architecture reviews, and continuous improvement efforts

Requirements

  • Bachelor’s degree in Computer Science or a related field, or equivalent practical experience
  • 3+ years of experience in software engineering roles
  • Strong backend development skills, preferably with Python, Go, Node.js, or similar languages
  • Proficiency in designing clear, maintainable APIs (e.g., REST, gRPC)
  • Experience working with databases (PostgreSQL, ClickHouse, Elasticsearch, or equivalents)
  • Solid understanding of system design, distributed systems, and cloud platforms (AWS, GCP, or Azure)
  • Clear communication skills and a collaborative working style

Nice to have

Familiarity with frontend development (e.g., React or similar frameworks) is a plus

What we offer

Compensation for this position includes a base salary, equity, and a variety of benefits
