What are the key skills and qualifications needed to thrive as a Freelance Integration Software Engineer, and why are they important?

To thrive as a Freelance Integration Software Engineer, you need strong programming skills (often in languages like Java, Python, or JavaScript), experience with APIs, and a solid understanding of system integration concepts, typically backed by a degree in computer science or related field. Familiarity with integration platforms (such as MuleSoft, Dell Boomi, or Zapier), cloud services, and relevant certifications (like MuleSoft Certified Developer or AWS Certified Solutions Architect) is highly valuable. Excellent problem-solving, communication, and time-management skills help you collaborate with clients and efficiently deliver solutions in a freelance environment. These capabilities are essential to ensure seamless connectivity between systems, deliver high-quality client solutions, and manage projects independently.

What are some common challenges a Freelance Integration Software Engineer might face when working with multiple clients?

Freelance Integration Software Engineers often encounter challenges such as managing different client expectations, working with diverse technology stacks, and aligning integration standards across various systems. Since each client may use unique tools and workflows, adaptability and strong communication skills are essential to ensure seamless integration. Additionally, coordinating with remote development teams and adhering to project timelines can be demanding, but these experiences also help build a versatile skill set and professional reputation.

What is a Freelance Integration Software Engineer?

A Freelance Integration Software Engineer is an independent professional who specializes in connecting and combining different software systems so they can work together seamlessly. They are typically hired on a project basis to develop, implement, and maintain integrations between applications, databases, APIs, and other digital services. These engineers ensure data flows smoothly across platforms, streamline business processes, and resolve compatibility issues. Freelancers in this role often work remotely and serve multiple clients across industries.

What is the difference between Freelance Integration Software Engineer vs Freelance Software Developer?

AspectFreelance Integration Software EngineerFreelance Software Developer
Primary FocusDesigning and implementing system integrations and APIsDeveloping standalone applications or features
Required SkillsAPI development, system architecture, integration toolsProgramming languages, application development, UI/UX

Job description

At Lilly, we unite caring with discovery to make life better for people around the world. We are a global healthcare leader headquartered in Indianapolis, Indiana. Our employees around the world work to discover and bring life-changing medicines to those who need them, improve the understanding and management of disease, and give back to our communities through philanthropy and volunteerism. We give our best effort to our work, and we put people first. We're looking for people who are determined to make life better for people around the world.
The Biologics Automation and High-throughput Technologies Group at the Lilly Biotechnology Center in San Diego is seeking an Advisor Lab Automation Software Engineer to help build the intelligent systems that connect software, data, and physical lab automation in antibody discovery. Our team is working toward a vision of closed-loop autonomous discovery - where robotic platforms, lab digitalization, and AI-driven orchestration work together to accelerate how biologics are found and developed. In this role, you will own the software integration layer between our automation infrastructure and the digital tools that drive it, while helping to shape how emerging AI capabilities get woven into that foundation over time. If you're a seasoned software and integration engineer who is excited about what AI might do for laboratory science, we want to hear from you.
In this role, you will have the opportunity to:
Lab Automation Integration
  • Lead the design and implementation of reliable software integrations between orchestration layers and physical lab systems including liquid handlers, plate readers, robotic workstations, and analytical instruments
  • Own and evolve the translation layer between high-level workflow logic and low-level instrument control
  • Partner with automation engineers and biologists to ensure integrations are robust, maintainable, and production-ready

Platform & Infrastructure
  • Deploy and maintain containerized services using Docker and Kubernetes with GitOps and CI/CD practices
  • Integrate cloud-based orchestration frameworks with laboratory control systems and LIMS infrastructure
  • Build scalable, production-grade Python applications and data pipelines that connect experimental readouts with downstream analysis tools

AI & Intelligent Automation
  • Collaborate with the team to explore and prototype how AI-driven decision-making can be incorporated into existing automation workflows
  • Contribute to the team's evolving approach to autonomous orchestration, bringing software engineering rigor to early-stage AI integration efforts
  • Stay current with developments in LLM tooling and agent frameworks and help evaluate what is practically applicable to the lab environment

Technical Leadership
  • Serve as a technical authority and mentor within the automation engineering team, helping to grow capability across software, integration, and emerging AI systems
  • Influence the broader technical roadmap for autonomous discovery systems at the San Diego site
  • Evaluate tools, frameworks, and vendor solutions for strategic fit with the team's long-term vision

What Success Looks Like
  • Lab automation systems are reliably connected, well-instrumented, and generating clean data that flows seamlessly into digital workflows
  • The team's software architecture evolves from early-stage integrations toward scalable, production-grade infrastructure
  • AI capabilities are thoughtfully and pragmatically incorporated into automation workflows as the field matures
  • Your technical leadership accelerates the capability growth of the broader automation engineering team

Basic Qualifications
  • Ph.D. in Computer Science, Software Engineering, Bioengineering, or related discipline with a minimum of 3 years of relevant industry experience, or
  • M.S. in a related discipline with a minimum of 5 years of relevant industry experience, or
  • B.S. in a related discipline with a minimum of 8 years of relevant industry experience
  • Demonstrated experience integrating software systems with laboratory automation platforms is required across all levels.

Preferred Skills & Attributes
Software Engineering & Infrastructure
  • Strong Python development skills with proven experience building and maintaining production-level applications (FastAPI, Redis, Flask, pytest, etc.)
  • Deep hands-on experience with Docker, Kubernetes, and CI/CD pipelines in production environments
  • Experience with cloud-based orchestration frameworks such as Argo on Kubernetes

Lab Automation & Integration
  • Direct experience integrating software control systems with lab automation platforms (liquid handlers, analytical instruments, robotic workflows)
  • Hands-on familiarity with common biologics discovery instrumentation - liquid handlers (Beckman, Hamilton, HighRes, etc.), micro-dispensers, plate readers, or integrated robotic workstations - is a strong plus
  • Familiarity with scheduling and execution software used in integrated lab environments (Cellario, Green Button Go, Director, SAMI, VWorks, Genera, or similar)
  • Experience with LIMS platforms, ELN systems, or laboratory data pipelines

AI & Emerging Technologies
  • Curiosity about and some hands-on experience with LLMs, agent frameworks, or AI-driven workflow automation
  • Familiarity with orchestration tools such as LangChain, LangGraph, or similar is a plus - deep expertise is not expected
  • Demonstrated willingness to learn and experiment with new technologies as they emerge
  • General
  • Proven ability to move fluidly between architectural thinking and hands-on engineering execution
  • Strong collaboration skills - comfortable working across software, automation engineering, and biological science teams
  • Genuine curiosity about biologics discovery and a desire to understand the science well enough to build systems that truly serve it
