Lead Software Engineer - Multiple Teams

Your Team's Impact 

The team comprises highly motivated engineers and stakeholders who are passionate about extracting targeted insights from diverse document sources and transforming them into high-value data products. Leveraging cutting-edge technologies, the team focuses on building scalable pipelines that efficiently collect, structure, and process large volumes of data.

Over time, the team has developed a robust and high-performing data pipeline capable of generating best-in-class structured datasets that power FactSet’s products. Currently, the team is advancing this ecosystem by driving end-to-end automation across multiple stages of the pipeline. This includes the development of an event-driven, GenAI-centric, agent-based infrastructure aimed at enhancing efficiency, scalability, and innovation in data processing workflows.

SUB-PROCESS BRIEF  

Leads development strategies, architecture designs, data management, and code flow analysis necessary for the software development life cycle. Works closely with different groups/teams to ensure engineering team delivers on precision/correctness, performance, and scalability across our distributed computational framework.

What You'll Do:-

• AI/ML & LLM Expertise:

  • Design, fine-tune, and deploy small and open-source large language models (LLMs) such as Llama, Mistral, OpenAI GPT, etc.

  • Hands-on leadership in prompt engineering, few-shot prompting, and building advanced NLP/NLU workflows.

  • Guide adoption of modern AI/ML frameworks (Hugging Face Transformers, LangChain, LangGraph, etc.) and architect reusable pipelines in Python.

• Python & API Development:

  • Drive critical systems architecture in Python, using best practices in API and microservices design (FastAPI, Flask, Django, etc.).

• Cloud Deployment (AWS/Azure/GCP):

  • Architect, deploy, and scale robust, production-grade ML/AI solutions on cloud (AWS strongly preferred), leveraging cloud-native tools (Lambda, S3, ECS/ECR/Fargate, etc.), serverless, and IaC (CloudFormation/Terraform).

  • Champion DevOps best practices, automation, containerization (Docker/K8s), CI/CD, and operational monitoring.

• Technical Leadership:

  • Mentor engineers, lead by example, drive system architecture reviews and code standards, and ensure high-quality technical delivery across teams.

  • Act as the technical point of contact for escalation, incident resolution, and production troubleshooting.

What We're Looking For:-

• Experience:

  • 8-12 years in software development, including 3+ in senior or lead roles delivering ML/AI solutions in a cloud environment.

• LLM & Prompt Engineering:

  • Strong real-world experience in LLM prompt engineering, few-shot prompting, and fine-tuning (using frameworks like Hugging Face, LangChain, LangGraph, etc.).

• Python Expertise:

  • Mastery of Python for API/microservice development, object-oriented patterns, code optimization, automated testing, and packaging.

• Cloud (AWS Preferred):

  • Hands-on deployment and scaling of AI/ML services on AWS, Azure, or GCP; proficient in containers, serverless, and infrastructure as code.

• Technical Leadership:

  • Proven experience mentoring software engineers, shaping system design, and driving cross-team initiatives.

• Communication:

  • Exceptional ability to explain complex technical subjects and influence technical direction with diverse audiences.

Nice to Have:-

• Databricks:

  • Experience building, deploying, or orchestrating ML/AI or data pipelines on Databricks (Data Engineering, MLflow, collaborative workflows, jobs).

  • (Note: Knowledge of Databricks is highly valued but not required; candidates without PySpark but with Databricks experience are welcome.)

• PySpark:

  • Experience using PySpark for big data ETL/processing, but not a must-have.

• Data Engineering:

  • Familiarity with Spark, Airflow, advanced data analytics stacks, and modern data lakes (e.g., Delta Lake).

• ML Productionization & MLOps:

  • Experience with ML lifecycle tools, CI/CD pipelines, monitoring, and model governance.

• Visualization:

  • Python-based dashboarding/analytics (Streamlit, Dash, Plotly).

• Security & Compliance:

  • Secure cloud design, IAM, encryption, and compliance frameworks.

• Published Work / Open Source:

  • Contributions to AI/ML communities, conference presentations, or technical publications.

Qualifications

• Bachelor's degree in Engineering, Computer Science, or equivalent.

• Experience working in product engineering organizations preferred.
