API Integration Engineer, Quark (Remote)

About the role

Quark, a publisher of content automation software, is hiring a remote API Integration Engineer. You will turn customer needs into working implementations on the Quark platform: configurations, REST API integrations, webhooks, SSO/SAML connections, XML/XSLT transforms, migrations and workflow automations. The work is technical, customer-facing and outcome-based, and you will use AI tools such as Claude Code or Cursor to speed up delivery.

Key responsibilities

• Turn customer requirements into technical implementation plans, acceptance criteria and delivery tasks.
• Configure Quark workflows, structured content models, rules, integrations and external data-source connections.
• Build and test REST API, webhook, SSO/SAML, XML/XSLT, migration and scripting-based automation deliverables.
• Diagnose implementation defects by analysing logs, payloads, authentication flows, transforms and configuration dependencies.
• Create concise runbooks, handover materials and walkthroughs so customers can operate the solution.

Required profile

• At least 3 years of hands-on software engineering, systems integration, implementation or technical consulting experience.
• Experience building or troubleshooting REST API and webhook integrations.
• Working knowledge of authentication concepts such as SSO or SAML.
• Fluent written and spoken English for customer discovery, requirements clarification and technical handover.
• Availability of at least 4 hours per day overlapping with US business hours and 4 hours for Europe.

Required skills

• Practical proficiency with XML and XSLT or an equivalent structured-data transformation technology.
• Proficiency in at least one scripting or programming language used for migration, automation or workflow implementation.
• Regular practical use of AI developer tools such as Claude Code or Cursor.
• Experience building at least one useful AI agent, Skill file, agent definition or similar automation artifact.

Nice to have: experience with content management or publishing platforms, creating customer-facing technical documentation and runbooks, and turning ambiguous requirements into end-to-end integrations or migrations. The role is full-time (40 hours per week), fully remote, and you will work as an independent contractor through the recruiter with weekly payments; pay is $7 USD per hour, about $15,000 USD per year.
