Senior Integration Developer

Are you an engineering‑minded consultant who loves diving into messy infrastructures, building what doesn’t exist, and helping clients navigate mission‑critical transformations?

If so, read on! About Us If it’s high-stakes, high-security, or highly complex—Oxalis is built for it. We’re a consulting and technology partner for the organizations that keep the world running:

• life sciences, shipyards, government agencies, health systems, aerospace programs, and manufacturers with missions too critical to fail.
• We serve the people behind the mission—those building, healing, defending, and delivering where it matters most.
• As a Platinum Solution Partner for Atlassian and a trusted systems integrator for IFS, we specialize in secure cloud transformation, IT service management, ERP modernization, and Operational strategy.
• We focus especially on organizations navigating compliance-heavy environments and complex change. About the Role As a Senior Integration Developer, you will drive technical execution on complex enterprise engagements.
• When projects hit blockers — missing integrations, broken automations, gaps between what the platform supports and what the business needs — you solve them.

That means writing scripts, building integrations from scratch, reverse-engineering configurations, and engineering your way through problems that off-the-shelf tooling can’t handle. You will work hands-on across the full engagement lifecycle:

• assessing environments, identifying technical risk, closing capability gaps, and validating outcomes.
• Over time, that technical credibility is what earns you the role of trusted advisor and modernization partner to client stakeholders — someone who can communicate decisions and tradeoffs clearly, and help organizations see a path forward when the technology gets complicated. Key Responsibilities Technical Execution & Problem Solving Identify and resolve technical blockers across all phases of migration — from pre-migration assessment through post-cutover stabilization. Reverse-engineer existing configurations, workflows, automations, and integrations to understand what must be rebuilt, replaced, or retired in the cloud. Build custom tooling, scripts, and integrations where vendor-supported solutions fall short — owning the solution end to end. Infrastructure & Systems Engineering Windows and Linux environments — server administration, permissions management, service configuration, and troubleshooting. SSH and remote access tooling to manage and diagnose infrastructure in hybrid and cloud environments. Manage environment variables, startup scripts, daemons, and scheduled tasks across platforms. Scripting, Automation & Development Write and maintain scripts in Python, PowerShell, Bash, or comparable languages to support migration validation, data cleanup, and operational automation. Build reusable accelerators and utilities that improve delivery efficiency across engagements. Data, Integrations & APIs REST and GraphQL APIs — interacting with platforms, extracting and transforming data, validating migration outcomes, and building or replacing integrations. SQL — validating data integrity and migration accuracy. Work with cloud-native integration patterns — webhooks, OAuth, event-driven architectures — to replace or redesign on-premises integrations. Atlassian Platform & Migration Own technical solutions and execution on Atlassian engagements — designing approaches, resolving blockers, and delivering outcomes hands-on. Support Atlassian migrations by providing technical expertise alongside JCMA and CCMA tooling — stepping in where vendor solutions hit their limits. Evaluate and mitigate technical risks related to scale, data integrity, performance, compliance, and user experience. Plan and execute phased migrations, test migrations, cutover strategies, and rollback plans. Identify and close technical gaps where Atlassian’s native capabilities, Marketplace apps, or existing integrations don’t meet business requirements — building solutions where none exist. Stakeholder Communication Translate technical decisions, risks, and tradeoffs into clear, actionable guidance for both technical teams and business stakeholders. Own the technical narrative on your engagements — from readiness assessments through post-migration reviews. Pre-Sales & Practice Growth Support pre-sales engagements including migration assessments, solution design, estimates, and proposal contributions. Contribute to Oxalis’ migration methodologies, accelerators, and internal knowledge base. Mentor consultants and share lessons learned across the practice. About You Extensive hands-on technical experience in enterprise environments. Demonstrated client-facing consulting experience. Linux and Windows systems administration — permissions, services, startup processes, and troubleshooting. SSH and remote infrastructure management in hybrid or cloud environments. REST and GraphQL APIs — building, consuming, and debugging integrations. Python, PowerShell, Bash, or comparable languages — writing real, working code, not just modifying samples. SQL — validating data integrity across migrations. Ability to communicate technical decisions and tradeoffs clearly to non-technical stakeholders. Bachelor’s degree in Computer Science, Engineering, or a related technical field — or equivalent hands-on experience. Preferred Qualifications Hands-on experience with Atlassian products — Jira, Confluence, or Jira Service Management administration and configuration. Exposure to Atlassian Cloud migrations and familiarity with JCMA and/or CCMA. Atlassian Certified Professional or Associate certifications. Experience with identity and access management — SSO, SAML, SCIM — in cloud environments. Background in regulated or compliance-heavy environments (e.g., public sector, healthcare, aerospace and defense). Experience with OAuth, webhooks, and event-driven integration patterns. Familiarity with GraphQL tooling (e.g., Postman, Insomnia) or API gateway configurations. Why Work for Us? Join Oxalis and be part of a team that’s transforming how regulated industries operate through cutting-edge solutions.
