Senior Backend Platform Engineer

Summary

Join a growing engineering team building intelligent data platforms that transform complex documents and large-scale datasets into actionable insights. This is a hands-on senior-level opportunity for a backend developer who enjoys solving challenging architecture problems, working with modern AI technologies, and owning solutions from design through production.

You'll help shape scalable cloud-native systems while influencing technical direction across high-impact products.

About the Opportunity

This organization is investing heavily in next-generation AI and data technologies to solve complex information challenges. As part of a highly collaborative engineering team, you'll work on systems that combine large-scale document processing, machine learning, search technologies, and cloud-native architecture.

You'll have the opportunity to build production-grade AI solutions, work directly with business and product stakeholders, and take ownership of critical platform capabilities that drive measurable business outcomes.

What You'll Do

Build Scalable Backend Platforms

• Develop and enhance distributed backend services that process high volumes of structured and unstructured data.
• Create reliable APIs, processing pipelines, and event-driven systems that support critical business applications.
• Design solutions that prioritize performance, scalability, maintainability, and operational excellence.

Develop AI & Intelligent Automation Solutions

• Build production-ready AI workflows leveraging modern large language models and retrieval technologies.
• Implement systems that transform documents, OCR output, and external data sources into accurate, actionable information.
• Improve data quality, search relevance, classification, and information extraction capabilities.

Drive Cloud & Data Architecture

• Design and maintain cloud-based applications utilizing modern AWS services and serverless technologies.
• Develop resilient systems with strong monitoring, observability, security, and automated deployment practices.
• Optimize processing efficiency, cost, and system reliability.

Collaborate & Influence

• Partner with engineering, product, and business teams to translate requirements into effective technical solutions.
• Contribute to architectural decisions and engineering best practices.
• Mentor teammates through technical leadership and thoughtful collaboration.

What You Bring

• Typically 5+ years of experience building backend applications, distributed systems, or data-intensive platforms.
• Strong Python development experience, including modern development practices, automated testing, and API design.
• Solid SQL and database design experience across relational and NoSQL environments.
• Experience building solutions within AWS or similar cloud ecosystems.
• Background working with event-driven architectures, microservices, or large-scale data processing systems.
• Experience integrating LLMs, AI services, or machine learning capabilities into production applications.
• Familiarity with document-processing workflows, OCR technologies, data extraction, or information management platforms.
• Strong problem-solving skills with the ability to navigate ambiguity and make sound technical decisions.
• Excellent communication skills and a collaborative mindset.

Preferred Technical Environment

Candidates who have worked with technologies such as the following will be particularly successful:

• Languages:

Python, TypeScript

• Backend Frameworks:

FastAPI, NestJS, GraphQL APIs

• Cloud & Infrastructure:

AWS, Serverless Architecture, Containers, Infrastructure as Code

• AI & Search:

Amazon Bedrock, OpenAI, Gemini, RAG, Vector Search, OpenSearch/Elasticsearch

• Data Platforms:

PostgreSQL, DynamoDB, Athena, S3

• Development Practices:

GitHub Actions, CI/CD, Automated Testing, Observability & Monitoring

• Frontend Exposure:

Angular or modern web application frameworks

Nice to Have

• Experience with retrieval-augmented generation (RAG), embeddings, model evaluation, or AI observability tools.
• Production experience with machine learning, NLP, search relevance, or entity resolution.
• Exposure to analytics and data modeling tools such as dbt or modern reporting platforms.
• Experience working in regulated environments involving healthcare, legal, financial, or sensitive data.
• Familiarity with AI-assisted software development tools and coding agents.
• Knowledge of legal technology, healthcare data, or enterprise information platforms.

Why This Role Stands Out

• Direct ownership of production AI and intelligent data platforms.
• Opportunity to work with cutting-edge LLM technologies at scale.
• High visibility across engineering, product, and leadership teams.
• A chance to influence architecture, platform strategy, and technical direction.
• Meaningful technical challenges involving AI, cloud architecture, search, data engineering, and automation.
