The Opportunity

We are looking for a dedicated, curious, and highly skilled Software Engineer to help architect and build intelligent, AI-native platforms that operate at global scale.

In this role, you will take ownership of critical technical components across intelligent application layers - from backend services and orchestration engines to front-end interaction models. You will build production-grade systems that integrate large language models, retrieval frameworks, enterprise APIs, and workflow automation capabilities.

The Work Itself

• Design and implement scalable AI-enabled services integrating LLMs, RAG pipelines, semantic search, and enterprise data systems

• Build orchestration layers supporting multi-step workflows, tool invocation, and context-aware task execution

• Develop secure, performant APIs that connect intelligent systems with internal platforms and data sources

• Contribute to full-stack development, including intuitive human–AI interaction experiences

• Ensure production readiness through monitoring, evaluation, observability, and performance optimization

• Improve reliability, latency, and scalability of AI-powered services

• Provide technical guidance to engineers within the team on complex system design and implementation challenges

• Contribute to reusable components and engineering best practices for AI-native development

Essential Functions

• Partner with product and engineering teams to translate AI-driven requirements into robust technical designs

• Independently lead the technical implementation of high-complexity features or subsystems

• Make critical architectural decisions within defined product or platform boundaries

• Identify technical risks early and propose scalable, maintainable solutions

• Contribute to documentation and knowledge sharing for AI-enabled system patterns

• Participate in sprint planning, estimation, and retrospectives.

• Apply secure coding practices and comply with regulatory and data protection standards.

The Skills You Bring

Advanced Systems Engineering:
Strong experience designing distributed systems, APIs, and scalable backend services.

AI Application Experience:
Hands-on experience building or integrating generative AI capabilities such as LLMs, RAG architectures, embeddings, semantic retrieval, or workflow automation.

Full Stack Proficiency:
Experience developing backend systems (e.g., Java, Python, C#, C++) and collaborating on or contributing to modern front-end frameworks.

Execution Depth:
Ability to independently deliver complex, cross-service features with attention to performance, reliability, and maintainability.

Enterprise Integration:
Experience integrating applications with internal APIs, data platforms, and secure enterprise environments.

Production Mindset:
Experience operationalizing AI-enabled services, including logging, evaluation, monitoring, and scalability considerations.

Collaborative Engineering:
Ability to work effectively across Product, Data Science, DevOps, and Agile teams.

We value engineers who combine deep technical expertise with curiosity about emerging AI technologies and who thrive in building complex, high-impact systems.
