About The Position

AGI Data Services strives to be best in class at acquiring, creating and
ground-truth data, with the highest standards of privacy and trust, to power the
best AI models on Earth.

We are seeking a Senior Software Development Engineer (Sr. SDE) who is
passionate about Generative AI and has strong engineering fundamentals to own
and accelerate the next generation of GenAI-powered tooling within AGI Data
Services. The Sr. SDE will design, build, and maintain LLM-as-a-Judge evaluation
pipelines that leverage large language models to assess data quality at scale —
including judge architectures, evaluation rubrics, scoring models, and
calibration mechanisms that align with the standards set by core scientist teams
developing Amazon Nova models. The Sr. SDE will also design and build
GenAI-powered workflow tools — such as conversational diagnostic agents,
automated quality assessment systems, and guided remediation workflows — that
streamline data collection and quality assurance processes, enabling
cross-functional teams to rapidly identify issues, reduce resolution time, and
continuously improve data throughput.

The Sr. SDE's work will directly improve Amazon Nova models. Our team has built
a strong foundation of GenAI-powered engineering practices — this senior role
will accelerate and scale that momentum. This role offers direct visibility to
VP and SVP leadership.

Requirements

• 5+ years of non-internship professional software development experience
• 5+ years of programming with at least one software programming language experience
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• Experience as a mentor, tech lead or leading an engineering team

Nice To Haves

• 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Bachelor's degree in computer science or equivalent

Responsibilities

• The Sr. SDE will own the LLM-as-a-Judge evaluation pipeline — designing, building, and scaling automated evaluation systems that leverage large language models to assess data quality. The Sr. SDE will architect judge pipelines, develop evaluation rubrics and scoring frameworks, build calibration and agreement mechanisms, and ensure judge outputs align with quality standards defined by core scientist teams.
• The Sr. SDE will design and build GenAI-powered diagnostic and workflow tools — including conversational troubleshooting agents, automated quality assessment tools, guided remediation systems, and workflow copilots. The Sr. SDE will leverage and extend agent orchestration frameworks such as LangChain, LangGraph, Amazon Bedrock Agents, or design custom orchestration layers tailored to AGI Data Services workflows.
• The Sr. SDE will build upon the team's existing GenAI-forward practices — introducing advanced patterns for prompt engineering, RAG, agent orchestration, and LLM evaluation into production systems. The Sr. SDE will design and implement robust backend services, APIs, and data pipelines on AWS leveraging Amazon Bedrock, SageMaker, Lambda, ECS/EKS, Step Functions, DynamoDB, OpenSearch, and S3.
• The Sr. SDE will collaborate with Applied Scientists, Technical Program Managers, domain experts, and vendor teams — bridging technology, process, and operations.
