Original job description

Job Title: AI Developer

Location: Montreal, QC

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).
