About Pattern Labs

Pattern Labs is Patterns AI Research & Development team a small high-autonomy group of software and AI engineers building the systems that make Patterns ecommerce acceleration platform AI-native. A sample of what were building today:

• An AI content engine that generates audits and optimizes marketplace product content at scale pairing LLM generation with deterministic compliance gates and evaluation loops so output is reliable enough to ship on behalf of global brands.

• Multi-agent research and insights pipelines that mine Patterns behavioral dataset of more than 91 trillion data points to surface trends opportunities and recommendations for brands.

• Product-data normalization systems that turn messy multi-marketplace catalog data into a clean store of record across 60 global marketplaces.

• Multimodal image intelligence automated tagging search and retrieval across large brand imagery libraries.

In this role you will work directly with the Director of Product AI R&D to define objectives and features against ambiguous business problems and from there youll have the autonomy to scope design build evaluate and ship end-to-end in collaboration with the rest of the team. This is a role for engineers who want room to explore: youll have a real opportunity to conduct research run experiments and then execute on your findings. You will take ownership of the end-to-end delivery of full-stack applications drive AWS architecture and execution and champion the technical integration of AI into core processes. Working in an environment with a dedicated budget for bleeding-edge technology you will mentor colleagues and build scalable systems that directly impact global ecommerce acceleration.

What is a day in the life of a Senior Software Engineer

• Architect build and deploy high-performing products from proof-of-concept through production in short iterative cycles.

• Perform heavy cloud infrastructure design and execution leveraging AWS services to support high-throughput data-intensive systems.

• Integrate generative AI capabilities (LLMs embeddings multimodal models agents) to address real business challenges and open new market opportunities.

• Make AI systems production-reliable: design evaluation harnesses guardrails and structured outputs so LLM-powered features ship with confidence.

• Work agentically: agentic coding tools (e.g. Claude Code Cursor) are a core part of our workflow youll help evaluate emerging AI models and set the teams standards for agentic development automated testing DevOps and observability.

• Guide engineering colleagues through architectural reviews code reviews pair programming and technical goal setting.

• Collaborate cross-functionally across global time zones partnering directly with product management design and engineering teams.

What will I need to thrive in this role

• 5 years of professional software engineering experience delivering production full-stack applications.

• Deep familiarity and hands-on expertise with AWS infrastructure; holding an AWS Solutions Architect Certification (or the ability to achieve certification rapidly) is strongly preferred.
