We're looking for a Lead Software Engineer to provide hands-on technical leadership across our Ruby on Rails platform, with a strong focus on DevOps, AWS, Kubernetes, and platform evolution. This role will help guide the transition from a single-tenant architecture toward a scalable, multi-tenant (Shopify-like) model, while also partnering closely with DevOps and engineering teams to identify, fix, and improve broken development and operational processes.
This role is both builder and fixer: writing production Rails code, improving infrastructure and delivery workflows, and raising the bar on reliability, scalability, and execution across teams.
Essential job Duties- Lead the design, development, and operation of Ruby on Rails services running on AWS, GCP and Kubernetes.
- Serve as a technical lead for evolving the platform toward a scalable, multi-tenant architecture, balancing long-term direction with near-term delivery.
- Write clean, maintainable, and well-tested Rails code while setting technical standards for the team.
- Partner closely with DevOps and development teams to improve CI/CD, deployment, and operational workflows.
- Identify and remediate broken or inefficient engineering processes, tooling gaps, and handoffs that slow delivery or increase risk.
- Design and review system architectures with a focus on scalability, reliability, and tenant isolation.
- Optimize application performance, database queries, background jobs, and infrastructure utilization.
- Improve production readiness through better monitoring, alerting, logging, and incident response practices.
- Participate in and help lead on-call rotations, root-cause analysis, and long-term corrective actions.
- Mentor engineers on cloud-native development, DevOps practices, and production ownership.
- Collaborate with Product, QA, and Engineering Leadership to align technical execution with business priorities.
Other Job Duties- Other duties as assigned by supervisor or HHAeXchange leader.
Travel Requirements- Travel 10-25%, including overnight travel
Required Education, Experience, Certifications and Skills- 7+ years of experience building and operating production-grade Ruby on Rails applications.
- Demonstrated experience in DevOps or platform-focused engineering roles, not just application development.
- Strong hands-on experience with AWS infrastructure (e.g., EKS/ECS, EC2, RDS, S3, IAM, CloudWatch).
- Practical experience deploying and operating applications in Kubernetes environments.
- Experience designing and improving CI/CD pipelines and release processes.
- Strong proficiency with relational databases such as MySQL and PostgreSQL, including performance tuning.
- Solid understanding of software architecture, system design, and tradeoffs at scale.
- Proven ability to debug complex production issues and drive them to resolution.
- Comfortable working in Agile development environments with cross-functional teams.
- Excellent written and verbal communication skills.
- Bachelor's degree or higher in Computer Science, Software Engineering, or equivalent practical experience.
- Willingness to explore and adopt AI tools responsibly to enhance productivity and innovation in your role
Preferred Qualifications- Experience leading or contributing to single-tenant - multi-tenant SaaS transformations.
- Experience with distributed systems, service-oriented architectures, or event-driven systems at scale
- Familiarity with Infrastructure as Code (Terraform, CloudFormation, or similar).
- Experience operating high-traffic, multi-tenant SaaS platforms.
- Familiarity with observability tools such as Datadog, New Relic, Prometheus, or Scout APM.
- Experience with containerization (Docker) and Kubernetes-based orchestration at scale.
- Knowledge of background job processing systems (e.g., Sidekiq, Resque).
- Experience modernizing large legacy Rails codebases.
