Job Description/Preferred Qualifications
The Senior Software Engineer builds and supports software systems that enable AI-driven capabilities in products and internal platforms. This role focuses on developing reliable services, APIs, and workflows that integrate machine learning and generative AI (where applicable) into real-world applications. The engineer works closely with AI/ML engineers, data engineers, and product partners to deliver features from design through production support.
Key Responsibilities
-
Develop backend services and APIs that integrate AI/ML capabilities into applications (e.g., inference endpoints, orchestration services, workflow automation).
-
Implement business logic around AI outputs, including validation, confidence handling, fallback behaviors, and human-in-the-loop patterns where needed.
-
Build integration layers to connect AI services with enterprise systems and data sources.
-
Own delivery of highly complex features/components with limited guidance: break down tasks, estimate effort, and deliver on schedule.
-
Write clean, maintainable code with appropriate abstractions and documentation.
-
Build robust testing (unit/integration) and ensure features meet performance, reliability, and security expectations.
-
Instrument services with logging, metrics, and tracing; support production monitoring and incident triage.
-
Troubleshoot issues across environments and participate in on-call/operational support rotations as applicable.
-
Apply basic responsible AI practices—logging, transparency, and guardrails—based on established team standards.
Required Qualifications
-
Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent experience).
-
5–7 years of professional software engineering experience delivering production applications/services.
-
Proficiency in at least one modern language such as Python, C#,etc..
-
Experience building APIs/services, working with databases, and shipping features via CI/CD pipelines.
-
Solid understanding of software engineering fundamentals: data structures, debugging, testing, and code quality.
-
Experience supporting AI or ML-enabled applications (e.g., integrating inference services, building orchestration around model outputs).
-
Familiarity with LLM application patterns (prompt orchestration, RAG basics, tool/function calling) and evaluation concepts.
Nice to Have
-
Experience with cloud platforms (e.g., Azure/AWS/GCP) and containerization (Docker/Kubernetes).
-
Exposure to event-driven systems (queues/streams) and observability tooling.
-
Experience with basic front-end development or building AI-assisted UX flows.
Core Skills
-
Backend Engineering: REST APIs, services, async processing, microservice patterns
-
Software Quality: unit/integration testing, CI/CD, code reviews, documentation
-
Operations: logging/metrics/tracing, performance tuning, incident triage
-
AI Integration (preferred): model inference integration, orchestration, guardrails/fallbacks
-
Data Fundamentals: SQL basics, data contracts, working with structured/semi-structured data
Minimum Qualifications
Doctorate (Academic) Degree and 0 years related work experience; Master's Level Degree and related work experience of 3 years; Bachelor's Level Degree and related work experience of 5 years
