Responsibilities:
- Design, build, and maintain complex, highly available services and applications, including robust system design (low-level design), API design, and data modeling across multiple domains.
- Lead end-to-end delivery of features and services, from technical design and implementation through deployment, monitoring, and ongoing optimization in production environments.
- Improve technical quality and operational excellence by driving code quality standards, reducing incidents, enhancing observability, and optimizing performance and reliability.
- Mentor and guide other engineers, sharing best practices in software engineering, testing, and architecture, and fostering a culture of continuous improvement and learning.
- Collaborate with product, design, data, and other engineering teams to translate business and customer problems into scalable technical solutions that can be reused across domains.
- Safely integrate and operate AI/ML‑enabled solutions that improve outcomes, including familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products.
Qualifications:
- Bachelor’s degree in Computer Science or a related technical field; or Equivalent related professional experience.
- 8+ years of professional backend software development experience in an object‑oriented language (e.g., Java, Kotlin, or similar)
- Proven experience owning end-to-end delivery for services or components, including design, implementation, testing, deployment, and support within a multi-service or domain environment.
- Strong proficiency in at least one modern programming language and core software engineering practices, including object-oriented design, data structures, algorithms, testing, and version control.
- Hands-on experience designing and consuming APIs, working with data models and storage systems, and applying system design principles to build reliable and maintainable systems.
- Preferred
- Experience designing and evolving service and application architectures for high-traffic, distributed systems, including clear API contracts, data models, and low-level designs.
- Demonstrated track record driving technical direction for services or domains, making data-informed tradeoffs on scalability, reliability, performance, and cost.
- Strong focus on operational excellence, including monitoring, alerting, incident response, and continuous improvement of production systems and developer workflows.
- Familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products, including safely integrating AI/ML‑enabled features into existing services.
- Experience leading cross-team technical initiatives or migrations, influencing engineering best practices across a domain, and mentoring others to grow their technical depth and delivery capability, including guiding teams on effective and responsible use of AI-assisted development and testing tools
