Job Description
Key Responsibilities
• Build AI-enabled features that generate client summaries from structured and unstructured data using OpenAI APIs and similar LLM providers.
• Integrate LLM calls into application services
- prompt construction, model selection, structured outputs (JSON), streaming responses, token-budget and cost management, retries, and error handling.
• Assemble context for the model
- retrieve and shape data from databases and internal APIs into the structured input the model needs to produce each summary type.
• Design and iterate on prompts and templates for different summary "types," and build lightweight evaluation to check accuracy, completeness, and faithfulness (no hallucinated facts).
• Expose capabilities through clean backend APIs so other teams can consume them.
• Apply responsible-AI guardrails
- PII handling/redaction, prompt-injection defenses, output validation, and audit logging suitable for a regulated environment.
• Collaborate with engineering, business analysts, and compliance stakeholders to define what a "good" summary looks like and to validate outputs.
• Use AI coding assistants (e.g., GitHub Copilot, ChatGPT) to accelerate your own development. Required Qualifications (Must Have)
• 3-5 years of professional software development experience as a hands-on developer (junior to mid-level).
• Strong proficiency in at least one backend language
- Java (with Spring Boot) and/or Python (FastAPI / Flask). We are open to either.
• Hands-on experience calling LLM APIs
- particularly the OpenAI API (chat completions, function/tool calling, structured/JSON outputs, embeddings)
- or a strong willingness and demonstrated aptitude to ramp up quickly.
• Practical prompt-engineering skills
- writing, testing, and iterating on prompts to get reliable, well-structured output.
• Experience integrating with data sources
- relational databases (SQL) and REST APIs.
• Solid understanding of RESTful API design and JSON.
• Good engineering fundamentals
- version control (Git), testing, and writing maintainable code.
• Awareness of data privacy / PII concerns and a careful, quality-focused mindset.
• Strong problem-solving and communication skills; able to work with non-technical stakeholders to shape requirements.
• Bachelor's degree in Computer Science, Engineering, or related field (or equivalent experience).
