Senior Software Engineer (Backend)

Healthcare benefits are messy for everyone: members, employers, even clinicians. At HealthJoy, we turn that mess into clear next steps. Our steerage engine is a layered, multi-agent and multi-modal AI pipeline paired with a real-time recommendation system that guides each member to the right care to reduce friction and cost across the American healthcare realm. This isn’t a lab demo; it’s in production, touching real people’s health and wallets every day.

You’ll join a seasoned engineering org to harden, scale, and evolve what’s already live. If you like applied AI with guardrails, high throughput data pipelines, and shipping reliable systems that measurably cut costs and time, you’ll feel at home here.

Your impact

We are looking for an ambitious senior software engineer with a deep desire to learn and develop software that improves people’s lives. If you’re passionate about developing the best software and collaborating with other engineers to do so, then we want to hear from you!

You will design, build and deliver AI-first product solutions, scale highly distributed systems, and continuously improve our AI-first engineering practices to further accelerate our market disruption, while making sure the quality is kept at superb level. You will get to work on the latest software practices and technologies, including microservices architecture, cloud design patterns, automated CI/CD pipeline, automated and orchestrated Kubernetes Delivery, and AWS platform. Above all, your work will impact people’s interactions with the healthcare system.

• Design & improve AI-first product engineering pipelines that will scale your mindset across all domains.
• Collaborate with engineering and product team members to improve quality, velocity and design problems through first principles.

• Design and implement new products into the HealthJoy platform

Your experience

• 5+ years of experience building and shipping scalable applications (Python, ideally)
• A superb understanding of software design principles and industry practices (for example: loose coupling, programming to interfaces). Taking into consideration test-driven approaches and observability using AI-first pipelines.
• AI-first mental model across the board: problem design first, data protocol first, architecture first, self-scalability mindset, context engineering, including the application of AI to identify and reduce hallucinations in AI<>Human product solution development lifecycle. Track record of developing on backend libraries such as Asyncio, Aiohttp, Flask, SQLAlchemy, or equivalent. Experience with relational databases (we use Postgres). Previous experience with data processing and manipulation workflows and implementation is a plus
• Experience working in an event-driven architecture and the utilization of microservices where applicable.
• At ease in the AWS ecosystem, working with a cluster architecture (we utilize Kubernetes)
• Experience participating in the architecture and design of new and existing products. An ability and eagerness to constantly learn and share knowledge with others
• Insatiable curiosity to learn new software principles, technologies, and tools
• Passionate about collaborating
