• Own the end‑to‑end lifecycle of features and services, including deployment, monitoring, incident response, and incremental improvement, while safely integrating and operating AI/ML‑enabled solutions that improve outcomes.

• Work across different parts of the stack or adjacent domains as needed, building familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products.

Minimum Qualifications:

• Bachelor's degree in Computer Science or a related technical field; or Equivalent related professional experience.

• 2+ years of relevant professional experience.

• Hands‑on proficiency in at least one modern programming language and related ecosystem, with experience in system design (LLD), API design, and data modeling for service‑oriented or microservices architectures.

• Experience owning features or services through development, testing, deployment, and operational support, including monitoring, troubleshooting, and resolving production issues.

• Solid understanding of core computer science and engineering fundamentals such as data structures, algorithms, distributed systems concepts, and secure coding practices.

Preferred Qualifications:

• Experience designing and implementing scalable, fault‑tolerant, and high‑throughput services, including well‑structured APIs and data models that serve multiple teams or domains.

• Demonstrated track record of improving service availability, performance, or reliability through metrics, observability, automation, and strong operational practices.

• Background integrating or leveraging AI/ML‑enabled components or platforms within production systems, and safely operating AI‑driven features to enhance customer and business outcomes.

• Experience working across multiple technical domains or layers of the stack (e.g., front‑end, back‑end, data, or platform services), adapting quickly to new technologies, patterns, and AI‑driven tooling.
