Backend / Integration Engineer with Security Clearance

About the Program: Innodata's Federal Practice builds the trusted data layer for critical infrastructure Trust & Safety work. Partnering with a leading systems integrator, we're delivering a modern, governed data services platform in a secure federal (IL4) environment. Over an intensive 20-week phase, you'll help stand up a data services storefront, a DataCard governance framework, synthetic data integration, and Databricks write-back capabilities. About this Role: As the Backend/Integration Engineer, you'll build the connective tissue of the platform. You'll develop the data services storefront's backend, stand up ingest pipelines, and implement reliable write-back into our data lakehouse so results flow cleanly across systems. Working alongside the Solution Architect, you'll make sure the platform's components integrate securely and perform under real workloads in a federal (IL4) environment. It's a strong fit for a backend engineer who likes owning integrations and turning architecture into working plumbing. Key Responsibilities: Implement Databricks REST API write-back for labeled outputs, DataCard provenance records, and synthetic content outputs
Build and validate the Duality back-end integration: catalog intake form configuration, parameter translation to Duality generation API, async job lifecycle management (submission, tracking, retry, completion), output handling
Implement ServiceNow REST integration for white-glove routing intake path
Build and maintain storefront backend services (API layer between frontend UI and platform components)
Implement DataCard write-back path in coordination with Solution Architect
Design and maintain async job queue management and retry logic across all integration surfaces

JSON schema design and structured metadata handling
Active Secret clearance with TS/SCI eligibility Nice-to-Have Qualifications: ServiceNow REST API integration experience
Federal program API integration background
ZenML or ML orchestration pipeline familiarity
React or modern frontend experience for storefront skeleton support The expected hourly salary range for this position is $75 to $80 p/hour, based on experience, skills, and qualifications. Note to Candidates:  The Databricks write-back and Duality integration are the two highest-complexity tasks in Phase B. Candidates should be prepared to discuss async API integration patterns and their approach to retry logic and error handling in federal-data environments during the interview.
