Job Description:
The Software Engineer 3 is a senior individual contributor who leads the design and delivery of complex, production-grade systems spanning multiple components. This role influences architecture, guides implementation, and raises the engineering quality bar across the team while remaining hands-on in critical areas.
You will work in a high-ambiguity environment, partner with technical and non-technical stakeholders, and make thoughtful trade-offs across scalability, performance, reliability, security, maintainability, and delivery. You will also apply an AI-first engineering approach while retaining accountable human judgement for every outcome.
Key Responsibilities:
- Lead the end-to-end design and delivery of complex features and systems across multiple components, from problem framing and technical design through deployment and production support.
- Own system-level technical decisions and ensure solutions align with established architecture, engineering standards, product goals, and long-term platform direction.
- Turn ambiguous business and technical problems into clear requirements, design options, delivery increments, and measurable acceptance criteria.
- Evaluate and communicate trade-offs across scalability, performance, reliability, maintainability, security, cost, and delivery speed.
- Design resilient, observable, and well-tested systems with clear data flows, failure handling, recovery behaviour, diagnostics, and operational ownership.
- Ensure secure handling of PHI and PII through strong access controls, validation, data protection, and adherence to healthcare compliance requirements.
- Use approved AI tools to accelerate design, implementation, testing, documentation, troubleshooting, and validation, while critically reviewing and owning all generated outputs.
- Set a high engineering bar through thoughtful code and design reviews, automated testing, production-readiness checks, refactoring, and continuous improvement.
- Guide implementation, resolve complex technical blockers, and mentor engineers through design discussions, code reviews, and knowledge sharing.
- Collaborate with Product Management, Architecture, Quality Engineering, Security, Cloud Operations, and other engineering teams to build alignment and deliver dependable outcomes.
- Communicate complex technical topics clearly to engineers, business partners, and leadership; create concise design documents and decision records.
- Use logs, metrics, traces, test evidence, and production data to validate assumptions, diagnose issues, and improve system health over time.
Required Qualifications:
- Bachelor's degree in computer science, Engineering, or a related discipline, or equivalent practical experience.
- Minimum 5 years of professional software engineering experience building and operating production systems.
- Strong hands-on programming experience in one or more modern languages such as Java, C#, Python, TypeScript, or JavaScript.
- Demonstrated experience designing large or complex systems spanning services, APIs, user interfaces, data stores, integrations, or pipelines.
- Strong knowledge of API design, distributed-system fundamentals, data modelling, performance, reliability, failure scenarios, and secure engineering practices.
- Experience with automated testing, CI/CD, source control, observability, production troubleshooting, and operational readiness.
- Ability to lead technical discussions, write clear designs, influence decisions, and build consensus across differing viewpoints.
- Experience mentoring engineers and improving engineering practices beyond individual feature delivery.
- Sound judgement when using AI-assisted engineering tools, including validation of correctness, security, maintainability, and compliance.
Preferred Qualifications:
- Experience building SaaS products, enterprise platforms, or high-volume transaction systems.
- Experience with AWS or another major cloud platform, containers, infrastructure automation, and cloud-native architecture.
- Experience with healthcare technology, payer-provider workflows, EDI transactions, or systems that process PHI and PII.
- Experience working with globally distributed product and engineering teams.
- Experience improving system reliability, performance, observability, developer productivity, or cloud cost efficiency through measurable outcomes.
Tools & Technologies:
The exact stack may vary by product area. Relevant experience may include:
- Languages: Java, C#, Python, TypeScript, JavaScript
- Frontend: React, Vue, HTML, CSS, styled components
- Backend and APIs: Java, .NET, Node.js, REST APIs, Swagger, OpenAPI
- Data and pipelines: Scala, Spark, S3, Parquet
- Testing and quality: Jest, NUnit, React Testing Library, Native Testing Library, mocking frameworks, ESLint, Prettier
- Delivery and operations: Git, GitLab CI/CD, Azure DevOps, npm, husky, logging and observability frameworks
- Developer and AI tools: Chrome DevTools, React DevTools, Vue DevTools, Insomnia, curl, GitHub Copilot, ChatGPT or other approved enterprise AI tools
What Success Looks Like:
- Complex systems are delivered with clear designs, predictable execution, and strong production readiness.
- Technical decisions visibly balance immediate delivery with long-term stability, scalability, security, and maintainability.
- Engineering quality improves through stronger design, testing, observability, documentation, reviews, and knowledge sharing.
- Cross-functional stakeholders understand key options, risks, trade-offs, and decisions.
- Other engineers become more effective through practical mentoring and reusable technical guidance.
Eligibility:
Video Camera Usage:
Availity fosters a collaborative and open culture where communication and engagement are central to our success. As a remote first company, we are also camera-first and provide all associates with camera/video capability to simulate the office environment. If you are not able to use your camera for all virtual meetings, you should not apply for this role.
Having cameras on helps create a more connected, interactive, and productive environment, allowing teams to communicate more effectively and build stronger working relationships. The usage of cameras also enhances security and protects sensitive company information. Video participation is required to ensure that only authorized personnel are present in meetings and to prevent unauthorized access, data breaches, preventing social engineering, or the sharing of confidential information with non-participants.
