About Us
Parallel is building the most intelligent way to query the web, with and for AIs. We are developing powerful retrieval, ranking, and reasoning systems to enable the next wave of agents, AI-native apps, human + AI workflows that require large-scale web intelligence. We’ve raised $30M in funding by Khosla Ventures, First Round Capital, Index Ventures (and many others).
As an API Engineer, you’ll play a critical role in designing, building, and optimizing our core APIs. You’ll work closely with our infrastructure, product, and customer teams to ensure our API is performant, scalable, and easy to integrate. This is a high-impact role where you’ll own key parts of our engineering roadmap and help define best practices for API development and architecture.
In this role, you will:
Design and develop the core shape of the API to support AI-native applications, ensuring usability, extensibility, and developer/agent experience.
Maintain API versioning and ensure backward compatibility, with a strong focus on long-term stability and clarity.
Optimize API performance through profiling, caching, and continuous system-level improvements.
Ensure security and reliability by implementing best practices for authentication, authorization, and data integrity in distributed systems.
Own and evolve SDKs to make it easy and intuitive for developers and AIs to use the API.
Define the roadmap for the developer ecosystem, including tooling and documentation.
Collaborate closely with customers and engineering teams to understand real-world use cases, gather feedback, and continuously improve the API.
Translate product requirements into API capabilities and work cross-functionally with product and backend teams for seamless integration.
Who You Are:
Thrive in a dynamic, 0-1 startup environment.
Experienced in building and maintaining APIs, with expertise in Node.js, Python, or Go.
Proficient in REST, GraphQL, and/or gRPC API design and development.
Have a strong understanding of databases (PostgreSQL, Redis, or similar) and distributed systems.
Passionate about developer experience, ensuring APIs are well-documented and easy to use.
Comfortable debugging and optimizing performance at scale.
A proactive problem solver who thrives on cross-functional collaboration.
Value working alongside driven, kind, and creative problem solvers.
Hold a bachelor’s degree in Computer Science, Software Engineering, or a related field.
