Job description

At WellSky, we are building impactful software solutions that prioritize end-user efficiency and shape the future of healthcare. Because we operate across multiple business units and product lines, our engineering teams tackle a diverse range of exciting challenges - from modernizing complex legacy applications to building brand-new, AI-native platforms.

We are looking for passionate problem-solvers to join us as Senior Software Engineers . Whether your expertise lies in distributed backend systems, modern frontend frameworks, or cloud infrastructure, you'll find opportunities here to make a massive impact.

Key Responsibilities

• Lead & Innovate: Design complex, scalable, and maintainable software features across various architectures (including microservices, DDD/CQRS, and event-driven systems).
• Collaborate: Work closely with solution managers, designers, and peers to translate requirements into technical specifications that align with our mission.
• Optimize Performance: Analyze technical challenges, identify system bottlenecks, and author technical documentation to optimize large-scale transactional processing.
• Elevate Code Quality: Facilitate code reviews, advocate for rigorous testing methodologies (unit, integration, end-to-end), and champion modern development best practices.
• Embrace AI: Leverage AI tools and platforms (like developer copilots) as an integral part of your daily workflow to enhance decision-making, code quality, and productivity.

Required Qualifications

• Bachelor's degree in a related field, or equivalent work experience.
• At least 4-6 years of relevant software engineering experience.

Preferred Qualifications

We operate across a wide variety of tech stacks to solve complex problems. You do NOT need experience with all of these to be a great fit. If you are highly skilled in a few of these areas and have a strong foundation in software engineering, our recruiting team will work with you to find the WellSky team that best aligns with your background!

• Backend: .NET/C#, Python (Django/Flask), Java, or Ruby.
• Frontend: Modern JavaScript/TypeScript, React, Angular, or Vue.
• Cloud & Infrastructure: GCP (preferred), AWS, Azure, Terraform, Docker, and Kubernetes/Helm.
• Architecture & Data: RESTful/GraphQL APIs, event-driven messaging (Kafka/RabbitMQ/PubSub), and relational/cloud databases (PostgreSQL, SQL Server, BigQuery).
• AI Tools: Experience or strong interest in using AI-assisted development tools (e.g., Claude Code).
• Domain Knowledge: Healthcare tech interoperability (FHIR, HL7, HIPAA, EMR), medical claims, or payroll accounting.

Job Expectations

• Willing to work additional or irregular hours as needed
• Must work in accordance with applicable security policies and procedures to safeguard company and client information
• Must be able to sit and view a computer screen for extended periods of time
