Role: Integration Engineer – EDI, API and Enterprise Integrations
Location: Largely remote; preference for candidates near Bloomington, MN; Austin, TX; or Kissimmee, FL
Travel: Ability to travel to a company site for a few days per month
Employment Type: Six-month contract-to-hire
Citizenship Requirement: Must be a U.S. citizen for conversion
Rate: $65-$75/hour W2
Position Overview
The Integration Engineer will design, build, troubleshoot, and support external customer integrations and internal system-to-system integrations across a growing semiconductor manufacturing company.
The organization has an immediate externally facing customer-integration initiative as well as numerous internal applications and data sources that do not currently communicate effectively. The company has not yet selected a formal enterprise integration platform, so this role requires someone with strong foundational integration experience who is comfortable working across multiple formats, protocols, systems, and architectural approaches.
This position is ideal for an engineer who understands EDI-style and commerce integrations but is not dependent upon one specific integration product.
Key Responsibilities
- Design, develop, test, deploy, and support integrations between customers, enterprise applications, manufacturing systems, data platforms, and internal business systems.
- Support a major externally facing integration initiative with one of the company’s customers.
- Develop internal integrations that allow currently disconnected systems and data sources to communicate.
-
Build integrations using formats and methods such as:
- EDI-style transactions
- CSV and other flat-file formats
- Pipe-delimited files
- XML
- REST or other APIs
- Batch and scheduled data exchanges
- Create mappings, transformations, validation rules, routing logic, and exception-handling processes.
- Work with business and technical stakeholders to define integration requirements, data contracts, source-to-target mappings, and operational expectations.
- Troubleshoot failed transactions, data-quality issues, connectivity problems, format discrepancies, and downstream processing errors.
- Implement logging, monitoring, alerting, retry, reconciliation, and support procedures.
- Document interface designs, dependencies, mappings, endpoints, credentials, schedules, support ownership, and recovery processes.
- Evaluate the current integration landscape and identify opportunities to standardize or simplify point-to-point connections.
- Provide technical input into the evaluation and selection of a future enterprise integration platform.
- Ensure new integrations are designed so they can transition into a formal integration platform once one is selected.
- Partner with the data-engineering team on integrations that feed enterprise data lakes, warehouses, analytics platforms, and AI solutions.
- Support appropriate security, access, segregation, and customer-data protection requirements.
Required Qualifications
- Strong experience designing and developing enterprise application or data integrations.
- Experience with EDI-style, commerce, customer-facing, or business-to-business integrations.
- Hands-on experience working with multiple formats, including CSV, delimited files, XML, and APIs.
- Ability to create source-to-target mappings and implement data-transformation logic.
- Experience troubleshooting integrations across source systems, networks, interfaces, transformations, and target applications.
- Understanding of authentication, authorization, encryption, secure file transfer, error handling, logging, monitoring, and reconciliation.
- Ability to work effectively without relying upon one specific integration platform or tool.
- Strong communication skills and experience partnering with internal teams and external customers.
- Ability to travel to a company location for a few days per month.
- U.S. citizenship and interest in converting to a permanent employee.
Preferred Qualifications
- Experience helping an organization evaluate, select, implement, or migrate to an enterprise integration platform.
- Familiarity with multiple integration platforms rather than expertise limited to only one product.
- Semiconductor, manufacturing, supply-chain, commerce, aerospace, automotive, medical-device, or other high-tech industry experience.
- Experience integrating legacy applications, manufacturing systems, ERP platforms, customer systems, and modern cloud applications.
- Experience with data integrations that feed analytics, data warehouse, data lake, or AI environments.
- Experience supporting integrations in secure, federally regulated, or customer-confidential environments.
Success Profile
The successful Integration Engineer will be a hands-on problem solver who can work through incomplete documentation, inconsistent legacy interfaces, and unclear system ownership. The company needs someone capable of understanding what good integration architecture looks like while also being willing to build mappings, troubleshoot files, inspect payloads, and personally resolve production issues.
Someone coming from a highly segmented organization—where separate teams handle every protocol, platform, mapping, deployment, and support function—may not be as successful as an engineer accustomed to owning integrations from discovery through production support.
Why This Opportunity
The Integration Engineer will help shape the company’s future integration strategy rather than simply inherit a fully standardized platform. The work will support customer relationships, enterprise modernization, manufacturing operations, analytics, and advanced semiconductor and quantum-computing initiatives.

What Employers Look For
The qualifications that appear most often in api engineer jobs.
- Proficiency designing and documenting RESTful APIs and OpenAPI specifications
- Experience with authentication protocols including OAuth 2.0 and API key management
- Hands-on work with API gateways such as Kong, Apigee, or AWS API Gateway
- Familiarity with GraphQL schema design and query optimization
- Bachelor's degree in computer science, software engineering, or a related field
- Experience writing integration tests and contract tests for API endpoints
Tips for Your Api Engineer Job Search
Tailor your resume to API specifics
List the API protocols you've worked with, such as REST, GraphQL, and gRPC, alongside the frameworks and gateways you've used. Hiring managers scan for these terms first, so generic backend descriptions will not get you past the initial screen.
Highlight versioning and deprecation experience
Many api engineer postings specifically call out versioning strategy and backward compatibility. If you've managed a v1-to-v2 migration or led a deprecation cycle, call that out explicitly in your resume's experience bullets, not just your skills list.
Filter openings by integration stack
API roles vary widely depending on whether the team uses OAuth, API gateways like Kong or Apigee, or internal service meshes. Targeting openings that match the tools you know best increases your interview-to-offer conversion significantly.
Apply early to roles that fit
Migrate Mate lists api engineer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Prepare a live API demo or public spec
A published OpenAPI spec or a small demo API on GitHub lets hiring managers evaluate your design sensibility before the first call. Interviewers frequently review candidates' public work ahead of technical screens for api engineer positions.
Negotiate on scope, not just compensation
After receiving an offer, ask about ownership over API standards decisions and involvement in roadmap planning. Api engineers who clarify design authority upfront tend to avoid friction later, and it signals seniority to the hiring team during negotiation.
Api Engineer Jobs: Frequently Asked Questions
Which companies are hiring the most api engineers?
The companies hiring the most api engineers right now include Eli Lilly, Cognizant, and JPMorganChase, with the largest share of openings in Texas, Virginia, and California, based on current listings on Migrate Mate as of August 2026. Fintech and enterprise SaaS companies tend to post the highest volume of these roles consistently.
How many api engineer jobs are remote?
About 75% of api engineer openings are fully remote or hybrid as of August 2026, reflecting the role's strong alignment with distributed engineering teams. Platform and integration-focused api engineer positions tend to be the most remote-friendly, while roles tied to on-premises infrastructure or regulated data environments more often require on-site presence.
How do you become a api engineer?
Start by building a solid foundation in HTTP fundamentals, RESTful design principles, and at least one backend language such as Python, Node.js, or Java. Work through projects that involve designing, securing, and documenting APIs end to end. Learn versioning strategies and authentication flows, then publish a real API with a public OpenAPI spec to demonstrate your work to employers.
Can you get hired as a api engineer with little experience?
Yes, entry-level api engineer roles exist, particularly at companies building internal developer tooling or expanding integration layers. Focus your applications on positions that list REST and OAuth as requirements rather than advanced gateway orchestration. A portfolio with a documented, functional API project carries significant weight when formal experience is limited, especially if it shows clean error handling and versioning.
What does the api engineer interview process look like?
Most api engineer interviews start with a recruiter screen focused on your background and tool familiarity, followed by a technical phone screen testing API design concepts and HTTP mechanics. A take-home or live coding exercise typically involves designing an endpoint or debugging an integration. Final rounds usually include a system design discussion and a conversation with engineering leadership about standards and ownership.
Where can I find and apply to api engineer jobs?
You can find and apply to api engineer jobs on Migrate Mate, which lists current openings from across the United States. Search the listings to find roles that match your experience and stack, then apply directly to each one that fits.
