Breezy HR is a remote-first hiring platform built for small and mid-sized businesses. Thousands of teams trust us to streamline recruiting from first touch to signed offer, and we’re passionate about delivering a fast, delightful experience for every candidate and every hiring manager.

We’re looking for a senior, hands-on engineer who can own projects end-to-end and ship quickly into production, especially as we expand LLM-enabled capabilities in our SaaS product. You’ll be a key technical contributor who turns ambiguous requirements into clean designs, pragmatic decisions, and reliable releases.

• Backend-first product engineering: owning customer-facing features end-to-end, from design to production release.
• LLM-enabled workflows using managed model APIs (AWS Bedrock): prompt design, structured outputs, evaluation, guardrails, reliability, cost/latency tradeoffs, and observability (production-first).

• 85% backend: Node.js services/APIs, integrations, data modeling, performance/reliability, and LLM-enabled feature delivery.
• 15% frontend: targeted UI changes to ship end-to-end outcomes (not a “frontend specialist” role).

• Lead delivery for major features: break down complex problems into solvable work, drive execution, and bring initiatives over the finish line.
• Build and evolve backend services: design, implement, and improve features across REST APIs, microservices, data ingestion/processing, and third-party integrations.
• Ship LLM-enabled features (AWS Bedrock): integrate managed LLM services into product workflows with production-grade reliability, monitoring, and practical guardrails; stay mindful of cost and latency.
• Own quality in production: debug issues across services and layers of the stack; raise the bar on correctness and performance.
• Cross-functional leadership: work extremely cross-functionally with Product; mentor others through reviews and collaboration.

• Backend: Node.js microservices
• Data: MongoDB and Redis
• Hosting: AWS
• Tooling: Git-based CI/CD; pragmatic “ship and iterate” mindset

• English (B2+): Can participate in technical discussions and write clear documentation/design notes in English.
• 7+ years building and shipping web applications
• Strong experience writing applications in Node.js and building scalable backend APIs/microservices.
• Experience with MongoDB (or similar NoSQL) and production data modeling.
• Comfortable using modern AI coding assistants to move faster without sacrificing quality (we use Cursor and Claude Code).
• Proven ability to work autonomously, learn new systems quickly, and deliver with a bias toward action.
• Clear communicator who documents decisions and trade-offs.

• Experience integrating LLM APIs into a production SaaS product (reliability, cost, safety, eval/monitoring).
• Frontend experience (React/Angular/Vue/Svelte) for occasional end-to-end shipping.

• Senior, low-ego, remote-first team. We value fast feedback loops, little yellow/red tape, and the ability to iterate at startup-like pace.
