About Grayscale:
At Grayscale, we believe the best frontline experience is powered by conversation—not forms or clunky software, but a simple text or WhatsApp message from your phone. Our conversational software automates critical hiring tasks like screening, interview scheduling, and onboarding, delivering a seamless frontline experience throughout the employee lifecycle. Trusted by leading brands like Hershey's, DICK'S Sporting Goods, and Walgreens, Grayscale is revolutionizing the way companies engage with their frontline teams.
About the Role:
We’re hiring a Senior Engineer to help build AI-powered product features using large language models (LLMs). This is a hands-on development role focused on production-grade applications powered by services like AWS Bedrock—not a machine learning research position. You'll be building end-user features from scratch, working with technologies like retrieval-augmented generation (RAG), vector databases, and real-time conversational AI. This role is ideal for engineers excited about applying LLMs to solve real customer problems in HR tech.
What You’ll Be Responsible For:
- AI-Powered Feature Development: Build and launch product features using LLMs (via AWS Bedrock), prompt engineering, and RAG patterns.
- System Design & Implementation: Contribute to the design and development of scalable AI-powered systems and APIs.
- Rapid Prototyping: Translate product ideas into functional prototypes and iterate quickly based on feedback.
- Cross-Functional Collaboration: Work closely with Product, Design, and Support to define requirements and deliver impactful features.
- Operational Support: Write well-instrumented code, contribute to monitoring efforts, and participate in on-call support when needed.
What We're Looking For:
- 4+ years of experience as a software engineer building user-facing products.
- Experience building and deploying LLM-powered features (AWS Bedrock, OpenAI, or similar).
- Familiarity with RAG, vector search, and embedding techniques.
- Experience with orchestration frameworks like Langchain is a plus.
- Strong backend development skills (Ruby on Rails preferred) and experience designing APIs (REST or GraphQL).
- Comfort building features from the ground up in a fast-paced, startup environment.
Tech Stack Overview:
- Backend: Ruby on Rails, PostgreSQL, Redis, Sidekiq, Shoryuken, Protobuf
- Frontend: React, Tailwind CSS
- LLM & AI Tools: AWS Bedrock, Claude
- Infrastructure: AWS ECS, EC2, S3, Kinesis, CloudWatch, Route 53, Elasticsearch
- Messaging & Pipelines: AWS SQS, AWS Kinesis
- Tooling: GraphQL (Apollo), Semaphore, GitHub, Datadog, Zoom, Slack
