Senior Integration Engineer
Remote | Full Time
United States
Divinity Software Group, LLC
Role Description:
Divinity Software is hiring a Senior Integration Engineer to own and build client integrations across the collections ecosystem.
This is a high-ownership role for a senior engineer who thrives in real-world integration work — distributed systems, inconsistent vendor APIs, legacy databases, and compliance-aware environments.
Our platform is multi-tenant and cloud-based, but every client integration ultimately connects through an on-premise gateway. Your primary responsibility will be building and maintaining our “Last-Hop Library” — client-specific integration components implemented as a set of C# interfaces and plugin-style libraries that dynamically bootstrap each client within our on-prem API. That on-prem API bridges our platform to the client ecosystem (systems of record, dialers, payment tools, etc.).
​
This is not a “ticket-taker” role. We’re looking for someone who can operate independently, communicate clearly, and own integration success end-to-end.
What You Will Do:
-
Own client integrations end-to-end: discovery → architecture → build → deployment → support
-
Implement and maintain client “Last-Hop” libraries in C#/.NET
-
interface-driven integrations
-
plugin-style components
-
tenant-specific bootstrapping inside our on-prem multi-tenant API
-
Build secure, resilient integration logic using:
-
REST APIs, webhooks, and messaging patterns
-
authentication flows (OAuth2, JWT, secrets management)
-
data mapping and transformation pipelines
-
Troubleshoot and resolve distributed integration issues across multiple services
-
-
Validate fixes through staged rollout:
-
dev → internal test → client test environment → production
-
-
Write and maintain integration documentation:
-
mapping specs
-
runbooks
-
troubleshooting guides
-
operational handoff notes
-
-
Improve the integration framework over time (reusable patterns, better reliability, better observability)
Requirements:
Must Have:
-
Strong C#/.NET Core experience is required
-
(This role is primarily backend C# integration engineering)
-
5+ years backend engineering experience
-
Proven experience owning production integrations end-to-end
-
Collections industry experience required
-
You understand terminology and workflows (placements, portfolios, disputes, dialers, payment flows, compliance awareness)
-
Strong distributed debugging ability:
-
You can trace failures across services and message flows
-
You can reason about state transitions and execution paths without full client-side access
-
You can isolate issues using logs, telemetry, correlation IDs, and inference
-
-
Strong documentation habits and clear async communication (remote-first execution)
-
​Comfortable debugging integrations that can’t always be reproduced locally (client-controlled environments, limited access, production-like issues)
​
Strongly Preferred:
-
Azure experience (Functions, Service Bus, App Services, Key Vault, Cosmos DB / SQL)
-
Experience with integration reliability patterns:
-
retries + backoff
-
idempotency
-
deduplication
-
durable workflows
-
-
Experience integrating with:
-
collections platforms / servicing tools
-
dialers/contact center systems
-
ACH/payment systems
-
bureaus/skip tracing/vendors
-
-
Familiarity with compliance-aligned engineering practices (PCI, SOC2, audit logs, access controls)
What Makes This Role Great:
-
High trust + high autonomy — you’ll be treated like an owner
-
Real-world engineering problems with real stakes
-
Remote-first culture built around strong async execution
-
Small team, high standards, meaningful impact
-
Your work directly affects client outcomes and platform reliability
This Role Is Not a Fit If:
-
​You need full debugger access and perfect reproduction to solve issues
-
You prefer tightly scoped work with constant direction
-
You don’t want to be accountable for integration outcomes
-
You avoid client-facing technical conversations
