Job summary

Earlytrade is seeking a Senior Integrations Engineer to design, build, and own the integration layer connecting us to ERP, project-management, accounting, and payment platforms. This backend-heavy role emphasizes reliability, complex partner scenarios, and scalable connections across REST, webhooks, and file-based workflows.

You’ll work with the COO & Co-Founder, an Integrations Product Manager, and partner teams to translate business requirements into robust, auditable integrations, improving

Qualifications

• 5+ years of professional software engineering experience, with at least 3 years focused on integrations, platform engineering, or systems connectivity.
• Direct experience integrating with ERP platforms in construction or mid-market environments.
• Strong backend engineering skills in Java and Spring Boot; experience with Apache Camel or a comparable integration framework is strongly preferred.
• Hands-on experience with OAuth2, API key management, and token-based authentication flows for third-party API connections.
• Proven ability to design reliable async and batch-oriented data pipelines: retry logic, idempotency, reconciliation, scheduling, and failure recovery.
• Experience with PostgreSQL: data modeling, query writing, and maintaining transactional integrity across integration boundaries.
• Strong understanding of data transformation patterns: field mapping, schema normalization, format conversion (JSON, XML, CSV, spreadsheets).
• Experience writing integration tests, contract tests, and monitoring/alerting setups that catch failures before customers do.
• Excellent technical communication skills: you can write clear specs, field mapping docs, and implementation guidance for internal and external teams.
• Experience working directly with external partner technical teams through discovery, implementation, testing, and production rollout.

Responsibilities

• Own the full lifecycle of integrations: discovery, design, build, testing, deployment, monitoring, and ongoing maintenance.
• Evaluate existing integration infrastructure and lead improvements to reliability, observability, scalability, and maintainability.
• Design integration architectures that are robust by default, with idempotency, graceful degradation, and auditability built in from the start.
• Work with product, revenue, and partner teams to scope new integration requirements and translate them into accurate technical specifications.
• Build and maintain Apache Camel routes and integration services across REST APIs, webhooks, and file or batch-based partner workflows with varying levels of technical maturity.
• Implement and manage async and scheduled processing patterns for high-volume, latency-sensitive, or operationally constrained partner data flows.
• Design embedded integration touchpoints where Earlytrade functionality or status needs to appear inside partner systems, while keeping the source-of-truth workflow architecture clean.
• Write thorough integration tests, contract tests, and end-to-end validation suites covering both happy paths and failure modes.
• Define and enforce data integrity standards for all data crossing integration boundaries, particularly financial and transactional records.
• Maintain clear, accurate technical documentation for every integration: data flows, field mappings, delivery modes, error codes, and escalation paths.
• Act as the internal technical authority on third-party platform capabilities, integration limitations, and best practices across API, webhook, and file-based delivery models.
• Act as the day-to-day technical counterpart for partner engineering and solutions teams during discovery, implementation, testing, and go-live.
• Contribute to architecture decisions that affect how integrations interact with Earlytrade’s core backend services.
