Job Title: Senior Back-End Developer (Java / .NET Core)
Location: Houston, TX (Hybrid - 3+ days onsite)
Employment Type: Full-time, Direct Hire
About the RoleWe are looking for a Senior Back-End Developer to join our internal Innovation & Software Development team in Houston. This role will lead the transition from low-code applications (PowerApps) to robust, custom-built solutions that streamline operations, improve efficiency, and support our growing healthcare/diagnostics environment.
You will work closely with our Director of Innovation, data architecture team, and front-end developer to design and build backend services, APIs, and data-centric applications that support critical workflows-such as licensing, compliance, digital pathology, and internal automation.
This is a hands-on, senior technical role with strong expectations for mentoring, collaboration, and impact in the first 90 days.
What You'll Do (Key Responsibilities)Platform & Application Development - Design, develop, and maintain back-end services and REST APIs using Java and .NET Core, supporting internal web and data applications.
- Help lead the transition from Microsoft PowerApps and other low-code tools to custom, scalable applications backed by SQL Server and modern cloud services.
- Build reliable integrations between applications, databases, and analytics platforms (including SQL Server and Databricks).
Architecture & Modernization - Collaborate with the Director of Data Architecture and data engineering team to define back-end architecture, data models, and service boundaries.
- Refine and evolve a primarily monolithic application landscape into a more modular, maintainable platform over time (no microservices today, but a modernization path ahead).
- Implement best practices for API design, error handling, logging, and security in a regulated, healthcare-oriented environment.
Collaboration & Mentorship - Partner closely with a junior front-end developer to ensure clean, well-documented backend interfaces that support high-quality user experiences.
- Provide technical mentorship across the Innovation team, sharing patterns, code reviews, and guidance on design and implementation.
- Actively participate in design sessions, backlog grooming, and sprint planning, contributing both technical input and business context.
Operational Excellence - Work with our managed IT partner (ECS) and internal teams to ensure solutions are secure, performant, and reliable within our infrastructure and cloud environment.
- Help establish and refine CI/CD pipelines using GitHub/GitLab and containerization tools (e.g., Docker) for consistent deployments.
- Contribute to technical documentation, system diagrams, and support hand-offs for production readiness.
What Success Looks Like (First 6-12 Months) - Within 90 days, you have a deep understanding of our existing PowerApps and custom applications, and are contributing production-ready code to at least one high-impact system.
- Within 6 months, you have successfully led or significantly contributed to at least one migration from a low-code solution to a custom backend/API-backed application.
- Within 12 months, you are recognized as a go-to technical leader for backend decisions, mentoring the front-end developer and improving the overall quality, performance, and reliability of our applications.
Required Qualifications - 8+ years of professional experience as a Back-End Developer / Software Engineer, with significant senior-level responsibilities.
- Strong hands-on expertise in Java and .NET Core for backend development.
- Proven experience designing and implementing RESTful APIs for internal or external applications.
- Solid experience with Microsoft SQL Server (schema design, stored procedures, performance tuning, query optimization).
- Experience working in a cloud environment, ideally Azure (App Services, hosting, identity, basic networking).
- Familiarity with modern development practices:
- Git-based version control (GitHub, GitLab, or similar)
- CI/CD pipelines
- Docker or other containerization tools
- Strong communication and collaboration skills, with experience working cross-functionally with product, data, and IT teams.
- Ability and willingness to work onsite in Houston at least 3 days per week.
Preferred Qualifications - Experience in healthcare, life sciences, diagnostics, or other highly regulated industries (HIPAA, SOX, or similar).
- Exposure to Databricks or other modern data/analytics platforms.
- Experience working alongside or integrating with low-code platforms (e.g., PowerApps) and helping teams migrate away from them.
- Prior experience mentoring junior engineers or acting as a technical lead on projects.
- Familiarity with container orchestration and infrastructure-as-code (Kubernetes, Terraform, etc.), even if not used in the current environment
About the Team & Environment - The Innovation team is a focused group (data architect, data engineer, analyst, PM, front-end dev, automation engineer) dedicated to building internal tools that eliminate manual work and improve efficiency.
- We are evolving from low-code, tactical solutions to more strategic, custom-built applications, and this role is central to that transformation.
