Combining the best of AI and human intelligence, Cresta improves the customer experience and powers revenue and efficiency gains across every channel.

About the Role

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.
Conclusion:

Compensation for this position includes a base salary, equity, and a variety of benefits. Actual base salaries will be based on candidate-specific factors, including experience, skillset, and location, as well as applicable local pay requirements. We are actively hiring for this role in Romania, the US, and Canada. Your recruiter can provide further details.

We have noticed a rise in recruiting impersonations across the industry, where scammers attempt to access candidates' personal and financial information through fake interviews and offers. All Cresta recruiting email communications will always come from the @cresta.ai domain. Any outreach claiming to be from Cresta via other sources should be ignored.  If you are uncertain whether you have been contacted by an official Cresta employee, reach out to recruiting@cresta.ai
