About the role:

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.

Responsibilities:

• 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.

Qualifications We Value:

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