DevSecOps Integration Engineer

Washington, DC

At i360technologies, we deliver business consulting and technology solutions that support the mission of federal agencies. We are seeking a DevSecOps / Integration Engineer to join our eight-member agile delivery team on a federal low-code application development contract. The DevSecOps / Integration Engineer owns the end-to-end integration execution layer for a 14-week Proof of Concept (PoC): standing up connector patterns, configuring authentication flows, managing the integration readiness tracker, and operating all deployment and monitoring tooling in parallel with core application development. This separation of concerns lets the Senior Software Developer focus on architecture integrity while the Integration Engineer drives interface delivery to schedule. This is a 100%-dedicated engagement running inside a two-week Scrum cadence within a FedRAMP-authorized, GovCloud-hosted environment. After the PoC, roll out additional applications over the entire period of performance.

Key Responsibilities

  • Build and maintain the integration readiness tracker covering all endpoint, credential, service-agreement, network, certificate, and test-data dependencies.
  • Identify and document REST, flat-file, and API patterns with client IT/enterprise systems owners.
  • Define interface specifications for all external system connections and confirm dependency owners and resolution timelines.
  • Stage source-control integration with the Government-managed CI/CD pipeline and prepare automated test scaffolding to execute within that pipeline.
  • Configure and validate authentication connectors, including SAML/OIDC federation against the client identity provider (internal users) and Login.gov with MFA (external partners).
  • Implement the first REST and flat-file connector patterns in Sprint 2 and stand up the interface test harness for sprint-internal validation.
  • Build read/write integration patterns to the client data platform (AWS data lake / Redshift / Snowflake) and structured error-handling logic in Sprint 3.
  • Deliver integration adapters for all external source systems in Sprint 4, including JWT and client-secret configuration and retry/circuit-breaker patterns across all connectors.
  • Collaborate with client technical leads on contract-first API design (OpenAPI specifications, mock services) when target APIs do not yet exist, so integration delivery is not gated on downstream system availability.
  • Execute integration hardening and support performance and scalability testing in Sprint 5, including load tests at 2× expected concurrency for 1,000 named users.
  • Capture and package integration evidence and configuration baseline artifacts for the security evidence package and ATO/A&A support in Sprint 6.
  • Operate deployment tooling and monitoring instrumentation across all sprints; maintain immutable audit logging across authentication events, configuration changes, and data access.
  • Resolve integration blockers within the sprint and report dependency status to the Project Manager for inclusion in the monthly COR report.

Qualifications

  • 5+ years of software integration, DevSecOps, or systems engineering experience on federal IT or enterprise software programs.
  • Demonstrated hands-on experience designing, building, and testing REST and SOAP API integrations, flat-file connectors, and webhook-based interfaces in production environments.
  • Experience configuring SAML, OIDC, OAuth 2.0, JWT, and client-secret authentication flows; familiarity with federated identity providers and MFA integration.
  • Proficiency implementing retry logic, circuit-breaker patterns, structured error capture, and alerting across distributed integration layers.
  • Experience operating Government or enterprise CI/CD pipelines (Git-based); familiarity with automated test scaffolding, configuration management, and deployment runbooks.
  • Hands-on experience in AWS (GovCloud preferred); working knowledge of FISMA, NIST 800-53, FedRAMP authorization boundaries, and ATO/A&A evidence requirements.
  • Hands-on experience configuring Unqork native connectors, REST/API integration modules, and authentication workflows within an Unqork tenant. Unqork Developer or Professional Configurator credential strongly preferred.
  • Broader experience integrating low-code or workflow platforms (Appian, OutSystems, ServiceNow, Power Platform, or equivalent) with external APIs and enterprise data systems is a plus, but does not substitute for Unqork experience.
  • Ability to deliver integration increments within two-week Scrum sprints; experience maintaining a dependency and readiness tracker visible to the full team.

Nice to Have

  • Familiarity with OpenAPI specification authoring and mock-service development for contract-first API design.
  • Hands-on performance testing experience (JMeter, Gatling, Locust, or equivalent) with documented load-test execution and results analysis.
  • AWS certifications (Solutions Architect, Developer, or DevOps Engineer – Associate or above).
  • SAFe DevOps, Scrum, or equivalent agile certification.
  • Experience supporting ISSO coordination, POA&M management, or security control assessments

Security & Eligibility Requirements

  • Ability to obtain and maintain a federal Public Trust (suitability) clearance
  • Must be able to pass a federal background investigation
  • U.S. Citizenship or Permanent Residency required (no visa sponsorship available)

Benefits

  • Referral Bonus
  • 401(k) Matching
  • Holidays - Eleven 
  • Retirement Plan (401k) Matching
  • Short-Term & Long-Term Disability
  • Life Insurance (Basic, Voluntary & AD&D)
  • Health Care Plan (Medical, Dental & Vision)
  • Paid Time Off (0-3 years - 15 Days PTO | 3+ years 20 Days)

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
