Internship Backend Developer Node Js Jobs in Kansas City, MO

Why DataMap

DataMap is an AI-first company. Every engineer here works with AI in the loop, and it changes the math on what one person can deliver. Work that used to take a team of five now takes one engineer who knows how to direct the tools. We put that in your hands early and expect you to use it. A growing share of what we deliver has AI at the center rather than bolted on the side, and the enterprises we work with are still working out what that means for how they run. We are the ones they call.

We build and implement financial and operations software for some of the largest companies in the world, including Google. We are a Microsoft, Coupa, Boomi, SAP, and Oracle partner, and most of our work sits where business process meets system design.

Most entry-level engineering jobs hand you a ticket queue and a five-year wait for anything interesting. This is not one of those. If you like making systems talk to each other, and you'd rather learn that on real client projects than in a training sandbox, this is where you find your ceiling.

How we hire

Apply, and you'll get a nine-minute problem-solving assessment. That's the entire first round. Score well and you get an interview, every time. No resume black hole, no weeks of silence.

The role

The Integration Developer builds and supports the middleware and custom applications that connect our clients' systems. Day to day that means Boomi, Workato, TypeScript, and Azure, moving data between platforms like Coupa, NetSuite, SAP, Workday, and Dynamics 365.

Not all of it is middleware. A good portion of our work is custom web applications: supplier portals, approval dashboards, reporting front ends, internal tools. Those are built in TypeScript and React and hosted on Azure. You'll move between the two kinds of work rather than being boxed into one.

You'll start with well-scoped assignments alongside a senior engineer and take on more as you learn the patterns. Client exposure comes early. Our engineers sit in the requirements meetings instead of picking up tickets three handoffs later.

What you'll do Recent graduates and early-career developers

• Build integration processes in Boomi AtomSphere and Workato with guidance from senior engineers
• Write transformation logic, data mappings, and validation rules
• Develop scripts and small services in TypeScript and Node.js
• Build React components and screens for client portals and internal tools
• Work with REST and SOAP APIs, webhooks, and JSON, XML, and CSV
• Support deployments across dev, test, and production
• Monitor running integrations, triage failures, and escalate with useful diagnostic detail
• Write interface specs, data mapping documents, and runbooks
• Support testing cycles: unit, SIT, and UAT

Candidates with 2+ years of experience

• Own individual integrations from technical design through go-live
• Build reusable connectors, error handling, and reconciliation reporting
• Develop full-stack features across React front ends and Node APIs, including auth, forms, and responsive layouts
• Deploy and maintain components on Azure (Functions, Logic Apps, Service Bus, App Service, Static Web Apps, Key Vault)
• Implement authentication against client systems with OAuth 2.0, API keys, or certificates
• Troubleshoot production issues and fix the cause rather than the symptom
• Work with functional consultants to turn business requirements into technical designs
• Take part in code reviews and improve our shared libraries and standards

Where it leads

We promote from within, and quickly for people who earn it. Integration Developers here typically move toward:

• Senior Integration Engineer owning architecture for enterprise integrations
• Principal Integration Engineer setting technical direction across the practice
• Solution Architect designing the full technical architecture for transformation programs
• Technical Lead running development teams across several client engagements

What we're looking for Recent graduates and early-career developers

• Bachelor's degree in Computer Science, Information Systems, Engineering, or equivalent practical experience
• Working proficiency in TypeScript, JavaScript, Python, Java, or C#
• Understanding of APIs, HTTP, webhooks, and common data formats
• Some exposure to modern web development: coursework, an internship, or personal projects
• Basic SQL and comfort querying and reconciling data
• Good analytical and debugging instincts
• Clear writing. Our engineers produce documentation that clients read.

Candidates with 2+ years of experience

• Hands-on development experience with an iPaaS such as Boomi, Workato, MuleSoft, or Azure Integration Services
• Proficiency in TypeScript and Node.js, comfortable in Git and modern tooling
• Experience building web applications in React, ideally with Next.js
• Working knowledge of Azure, or AWS/GCP with willingness to move to Azure
• Experience building and consuming REST and SOAP APIs and webhooks, including authentication flows
• Familiarity with ERP or business-system integrations (Coupa, NetSuite, SAP, Workday, Dynamics, Salesforce)
• Experience supporting production systems and diagnosing live issues
• Boomi or Workato certification, or willingness to get one

Benefits

• Competitive base salary and performance-based bonuses
• Unlimited vacation and a flexible work environment
• Free catered lunch at HQ
• 401(k) with employer match
• Health insurance with a generous employer contribution
