Vic.ai, Inc. is seeking a Senior Backend Engineer to join the team behind our AI-first iPaaS.

You will build and operate the integration platform that connects customers' ERP and financial systems to Vic.ai, with data syncing at scale and AI-assisted onboarding. You will work on backend services in TypeScript/Node.js, Elixir/Phoenix, and Python, and contribute to API design, observability, and reliability across the stack.

Qualifications

2+ years building and operating production backend systems in TypeScript/Node.js, Elixir/Phoenix, or Python.
Experience integrating with REST, SOAP, OData, OAuth2, and webhooks.
Experience building on top of LLMs and AI-powered integrations.

Responsibilities

Build and operate integrations that move data bidirectionally between customers' ERP systems and Vic.ai.
Develop backend services in TypeScript/Node.js (HTTP APIs, queue-based workers, PostgreSQL).
Design integrations against third-party APIs (REST, SOAP, OData, OAuth2) with explicit, typed contracts.
Make jobs idempotent and replay-safe, including retries, rate limiting, dead-lettering, and correlation/audit logging.
Own services from development through production, including deployment on AWS, monitoring, and issue resolution within defined SLAs.
Contribute to the AI-assisted tooling that speeds up customer onboarding.
Support adjacent backend domains as needed (Public API and core services in Elixir/Phoenix, plus Python services).
Contribute to architectural decisions and long-term platform scalability.
Identify, troubleshoot, elevate, and resolve issues related to performance, accuracy, and system stability.
