Senior Backend Engineer

Base Compensation: $150K - $180K

Join Wellth's engineering team and help build systems that have already prevented 15,000 hospital days and saved 530 lives. Our technology reduces hospitalization rates by up to 44% for underserved populations, directly impacting the lives of over 50,000 patients daily.

As a Senior Backend Engineer, you'll architect scalable solutions that handle sensitive healthcare data with 99.9% uptime requirements while serving millions of patient interactions. You're not just building another app—you're creating technology that measurably improves health outcomes in the $88B health outcomes market.

You'll design and build systems that tackle unique engineering problems:

• Scale healthcare interactions from thousands to millions while maintaining sub-second response times on complex medical data queries
• Architect fault-tolerant systems for mission-critical healthcare workflows where downtime directly impacts patient care
• Build secure data pipelines that process highly sensitive healthcare records while maintaining HITRUST certification
• Design automated scaling solutions that handle unpredictable traffic patterns in healthcare environments
• Optimize database performance across both relational and NoSQL systems, managing massive patient datasets
• Implement monitoring and alerting strategies that ensure 99.9% uptime for business-critical systems

Working with healthcare data, you'll solve complex challenges related to patient population selection algorithms, care prioritization systems, and cost-effective data enrichment solutions that directly impact patient outcomes.

You will:

• Own end-to-end system design for services powering Wellth's mobile app and business-critical healthcare systems
• Lead operational excellence initiatives, including incident response, post-mortems, and reliability improvements
• Architect scalable solutions that grow with our expanding patient population and data requirements
• Drive developer experience improvements through shared tooling, documentation, and SDLC process optimization
• Mentor and guide other engineers, amplifying team capabilities and technical standards
• Ensure data security and compliance following secure SDLC guidelines for HITRUST certification

We're looking for an engineer with:

• 5+ years building production services with Node.js and TypeScript at scale
• 5+ years of operational experience troubleshooting, monitoring, and optimizing production systems for reliability and performance
• 3+ years with cloud infrastructure (AWS, GCP, or Azure) using Infrastructure as Code (Terraform or CloudFormation)
• 5+ years working with databases, including both relational and NoSQL systems, with experience in query optimization and scaling strategies
• Strong collaborative experience contributing to shared codebases, implementing developer tooling, and knowledge sharing through documentation and technical presentations
• Proven track record solving complex technical problems with reliable, scalable solutions

Your background should include:

• Production monitoring expertise with APM tools (DataDog, New Relic, or similar)
• CI/CD pipeline design and deployment automation (GitHub Actions, CircleCI, or Jenkins)
• Pub/sub architecture experience with message queues (RabbitMQ, Kafka, Amazon SQS)
• Search and analytics platforms (ElasticSearch, Solr, or alternatives)
• Data warehouse experience (Redshift, BigQuery, Snowflake)
• Security-focused development, especially with sensitive data in healthcare, financial, or government contexts
• Testing expertise in unit and integration testing for critical system validation

We'd love to see:

• Healthcare industry experience working with medical data and compliance requirements
• Data orchestration tools experience (Airflow, Fivetran, or similar)
• API development expertise in both RESTful and GraphQL architectures
• AI-assisted development experience using tools like Claude Code, Cursor, Gemini CLI, or similar AI code assistants for enhanced productivity
• Agile development experience in Scrum or similar methodologies
• Container orchestration knowledge (Kubernetes, ECS)

You'll work closely with:

• Cross-functional engineering teams, including frontend, backend, and quality engineers, building integrated solutions
• Data engineers designing ETL pipelines and data transformation workflows
• Product managers defining new capabilities and prioritize business-critical features
• Internal stakeholders are optimizing systems to meet evolving business needs
• Our Director of Engineering focused on your technical growth and career development through regular mentoring and technical leadership opportunities.

• Direct patient impact: Every system you build directly improves health outcomes for underserved populations
• Technical ownership: You'll have significant autonomy in architectural decisions and technical direction
• Growth opportunities: Clear paths for technical leadership and system architecture ownership
• Collaborative culture: We value diverse perspectives and non-traditional career paths to engineering
• Mission-driven work: Join a team singularly focused on improving healthcare access and outcomes

We support work-life balance through:

• Flexible hybrid arrangements: Strong remote-first practices with optional collaboration in our Marina Del Rey office space
• Comprehensive time off: Robust PTO and generous parental leave programs
• Health and financial benefits: Full health, dental, vision insurance, FSA/HSA plans, and competitive equity package
• Professional development: Conference attendance, learning budgets, and internal tech talks
• Impactful mission: The opportunity to measurably improve healthcare for those who need it most

We encourage applications from candidates of all backgrounds, including those with non-traditional paths to engineering. We value diverse experiences and perspectives in building technology that serves everyone.
