About Growthline Partners
Growthline Partners is a business software and consulting firm serving SMB manufacturers, distributors, and project‑centric companies. We design and implement integrated enterprise platforms across Zoho, Salesforce, and Microsoft—bringing together CRM, project/accounting, analytics, and modern AI to drive measurable outcomes.
The Opportunity
We’re building an internal AI-powered SDR demo to showcase agentic automation for prospecting, outreach, CRM updates, and follow‑ups. The solution combines n8n for orchestration, Lyzr (agentic AI) for reasoning, Microsoft Graph for Outlook/Teams, LinkedIn enrichment, and Zoho CRM as the system of record. We need a hands‑on engineering lead to own backend integration—designing APIs, connecting tools, and standing up reliable workflows that can scale and be extended for client-facing implementations.
Responsibilities
·
Own the backend integration layer: implement robust workflow orchestration in n8n, integrate agent endpoints, and connect enterprise SaaS APIs.
- Stand up and secure services for agentic components (e.g., FastAPI/Flask); manage auth flows (OAuth2/tenant apps) for Microsoft Graph and Zoho CRM; enforce data consistency with Zoho as the source of truth.
- Build adapters/connectors for Lyzr agent endpoints and LinkedIn enrichment; normalize and log activities to CRM with auditability.
- Instrument reliability and observability (idempotency, retries/backoff, DLQs, metrics, health checks, alerting).
- Collaborate with prompts/KB/process owners to translate playbooks into callable services and reusable workflows; contribute to technical docs and demo handoff packs.
- Harden security & compliance: secrets management, token refresh, role‑based access, PII handling; align with scalable deployment (Docker/Kubernetes, cloud).
Requirements
- 5+ years in backend engineering/integration for SaaS platforms; strong API design (REST/GraphQL), webhooks, event‑driven architecture.
- Proven experience with workflow engines (preferably n8n) and Python services (FastAPI/Flask), including containerization and CI/CD.
- Hands‑on with Microsoft Graph (Outlook mail send, Teams notifications) and Zoho CRM APIs, OAuth scopes/permissions, and CRM activity logging.
- Practical exposure to agentic AI platforms (Lyzr, LangChain) and integrating AI outputs into deterministic workflows.
- Reliability mindset: structured logging, tracing, metrics/monitoring, circuit breakers, idempotency, and robust error handling.
- Clear written communication and the ability to document architectures and hand off to delivery teams.
Nice to Have
· Experience with LinkedIn APIs for lead enrichment and compliance‑aware usage.
- Background in manufacturing/distribution/project‑centric businesses or consulting integrations across Zoho/Salesforce/Microsoft.
- Knowledge of vector databases and memory for agent workflows (e.g., Pinecone/Azure Cognitive Search).
How We Work
You’ll join a small, senior team that values speed with rigor—shipping demos that are client‑ready while maintaining enterprise‑grade fundamentals (security, reliability, traceability). We prioritize pragmatic design, clean interfaces, and documentation that lets others build on your work.
