Senior Application Engineer - AI (Python, FastAPI & LLM)

Guidewire Software; Bengaluru; On-site; INR 2,800,000 - 4,200,000; Full time

Job summary

Guidewire is seeking a Senior Applicaton Engineer to join our Professional Services AI Engineering team in Bangalore. You will own the dev work for features end-to-end, delivering production-grade, customer-facing AI capabilities on Strike Teams and collaborating with the AI Engineer to integrate LLM-based components into production paths on AWS Bedrock.

You will operate within platform blueprints, focus on shipping, and mentor junior engineers while maintaining strong code quality, testing, and

Qualifications

• 5-8+ years of software engineering experience, with a strong focus on backend or full-stack production development.
• Expert-level Python and the surrounding production ecosystem (async, FastAPI, Pydantic, pytest). Experience with Java or TypeScript is useful, though Python is strongly preferred.
• Strong REST API design experience, database modeling (SQL and at least one NoSQL store), and event-driven patterns.
• Working knowledge of frontend frameworks (React or equivalent) sufficient to wire UI components into your APIs.
• Working understanding of LLM APIs and how AI features are integrated — prompt invocation, streaming, retries, fallbacks. You'll partner with AI specialists on the modeling and data-science work, contributing to the integration design and knowing when to bring in the AI Architect.
• Experience with coding assistants (Claude Code, Copilot).

Responsibilities

• End-to-End Feature Delivery: Own the dev work on a Strike Team — REST APIs, frontend wiring, feature logic, and integration with AI components — for one high-complexity or strategic AI productization project at a time.
• Technical Execution: Make day-to-day implementation calls, contribute to design reviews, and make sound trade-off decisions on your features; elevate cross-cutting concerns to the Engineering Manager.
• AI Integration: Partner with your AI Engineer to bring LLM-based components into production paths — prompt invocation, response handling, fallbacks, observability — running on AWS Bedrock. You'll shape how these components are integrated, collaborate on the design decisions that affect the product, and bring the AI Architect in on the deeper algorithmic calls.
• Platform & Standards Consumption: Build on top of the team's shared CI/CD, vector DB, auth, QA, and UI/UX foundations. Push back to the horizontal layer when something is missing or wrong.
• Code Quality & Mentorship: Set a high bar for code review, testing, and engineering hygiene through your own work. Mentor the Consultant Product Engineer and the AI pairing partners.
• AI-Native Development: Leverage AI coding tools (Claude Code, Copilot) to accelerate delivery while maintaining a high quality bar.

Summary

Guidewire is seeking a Senior Applicaton Engineer to join our Professional Services AI Engineering team in Bangalore. In our Core & Satellite model, you will work on the development side of our Strike Teams — reporting to the Engineering Manager and pairing with a Senior AI Engineer to deliver production-grade, customer-facing AI features end-to-end.

This is a hands-on senior engineering role. You own the dev work for your features end-to-end, build using AI coding tools like Claude Code, and operate inside platform blueprints set by the Platform Architect, AI Architect, and QA Architect — so you can focus on shipping the product rather than re-inventing infrastructure.

Job Description

• End-to-End Feature Delivery:Own the dev work on a Strike Team — REST APIs, frontend wiring, feature logic, and integration with AI components — for one high-complexity or strategic AI productization project at a time.
• Technical Execution:Make day-to-day implementation calls, contribute to design reviews, and make sound trade-off decisions on your features; elevate cross-cutting concerns to the Engineering Manager.
• AI Integration:Partner with your AI Engineer to bring LLM-based components into production paths — prompt invocation, response handling, fallbacks, observability — running on AWS Bedrock.

• AI-Native Development:Leverage AI coding tools (Claude Code, Copilot) to accelerate delivery while maintaining a high quality bar.

KPIs & Success Metrics

• End-to-end delivery of high-complexity or strategic projects on schedule.
• Quality bar upheld: review standards, test coverage, and observability for owned features.
• Reliable AI integration — LLM-backed paths with sound fallbacks and acceptable latency.
• Mentorship impact: growth of the Consultant Product Engineer and AI pairing partners.
• Platform feedback loop: gaps surfaced and resolved with the horizontal teams.

Experience:

5-8+ years of software engineering experience, with a strong focus on backend or full-stack production development.

Technical Proficiency

• Expert-level skills in Python and the surrounding production ecosystem (async, FastAPI, Pydantic, pytest). Experience with Java or TypeScript is useful, though Python is strongly preferred.
• Strong REST API design experience, database modeling (SQL and at least one NoSQL store), and event-driven patterns.

• Experience with coding assistants (Claude Code, Copilot).

AI in Production:

Has taken LLM or RAG features to production and kept them running — streaming, fallbacks, cost controls, and observability.

AWS:

Hands-on with Lambda, ECS, API Gateway, RDS, and Bedrock — and aware of the timeout, concurrency, and cost limits that catch LLM workloads out.

Engineering Excellence:

Track record of shipping production features end-to-end. Strong CI/CD, Git workflow, automated testing, and observability habits.

Domain Context:

(Preferred) Experience with enterprise software, regulated industries, or multi-tenant SaaS.

Preferred Skills & Experience

• Guidewire Knowledge:Prior experience with Guidewire InsuranceSuite or Guidewire Cloud is a significant plus.
• Team Leadership:Prior experience leading small teams or owning a feature area end-to-end.
