Résumé du poste

Horizon3.ai seeks a Software Engineer for the API Platform team to build and improve the internal API layer powering NodeZero. You will ensure reliability, low latency, and strong developer experience for customers and integrations.

You’ll join a small team led by senior engineers, contributing to API consolidation, versioning, rate limiting, and observability, with a roadmap across services. This is a fully remote role with travel up to 5%.

Qualifications

• 2+ years of professional software engineering experience building production backend services.
• Proficiency in Go or strong motivation to ramp quickly—Go is the primary language on this team.
• Solid understanding of REST API design principles and HTTP semantics; experience with gRPC is a plus.
• Ability to reason about service reliability: latency, error rates, retry behavior, and circuit breaking.

Responsabilités

• Implement and maintain API endpoints and middleware in Go.
• Build and evolve the API gateway layer — routing, authentication, rate limiting, and request/response shaping.
• Write and maintain API contracts (OpenAPI/gRPC definitions) and communicate breaking changes to internal consumers.
• Contribute to service reliability: monitoring, alerting, SLA tracking, and incident response for platform APIs.
• Write clear, reviewable code with tests.
• Collaborate with Data Ingestion, Integrations Platform, and Client Platform teams who consume the APIs you build.
