What You'll Do:

Own the platform integrations layer end-to-end — building reliable connectivity, data ingestion/exports, and orchestration for complex, multi-step, long-running processes (including retries and state management)

Build and maintain both inbound and outbound integrations with third-party platforms (e.g., Salesforce and other external/open APIs)

Design and implement in-house services capable of processing large volumes of data under tight time constraints, optimizing for throughput and latency

Design and maintain RESTful and webhook-based APIs, applying strong patterns for rate limiting, pagination, error handling, versioning, and backward compatibility

Collaborate with product and platform teams to define integration requirements and execution guarantees (SLAs/SLOs)

Build observability (logging, tracing, metrics) into integration systems, and use it to monitor, troubleshoot, and continuously improve production reliability

Lead medium/large feature development independently within agile processes, mentoring engineers and conducting code reviews along the way

Stay current with emerging technologies and evaluate new tools for potential adoption

What You Bring:

5+ years of software engineering experience with a focus on backend systems

Strong experience with Node.js (NestJS), JavaScript, and TypeScript; Java (Spring Boot) is a plus

Proven experience integrating with external/third-party APIs, building both inbound and outbound integrations (any platform — pattern/concept experience is transferable)

Demonstrated experience building high-volume data services — e.g., optimizing data processing/ingestion time under real-world constraints

Strong problem-solving and analytical skills, with the ability to debug complex technical issues and implement robust solutions

Solid understanding of authentication and authorization protocols, including OAuth 2.0, OIDC, SAML, and JWT

Proficiency with MongoDB and comfort working across relational and NoSQL data stores; familiarity with React a plus

Strong communicator, comfortable leading cross-functional collaboration with both technical and non-technical stakeholders
