Senior Software Engineer

Key Responsibilities

• Design, build, and operate the backend services and APIs that power talent matching in production
• Build asynchronous, event-driven APIs and pipelines that stay fast and reliable under load
• Partner with Data Science to take their matching and language models from prototype to reliable production services
• Use AI-assisted development daily to design, write, test, and review code, and help set our standards for it
• Own quality for what you ship: testing, monitoring, latency, and cost
• Collaborate with Product and Operations to turn real recruiter and candidate needs into shipped features

What We're Looking For

• 5+ years of software engineering experience with strong Python skills
• Hands-on experience designing and operating production APIs and backend services at scale
• Experience designing asynchronous APIs (queues, events, webhooks, or streaming) and reasoning about concurrency
• Comfortable in a stack like ours: Python on AWS, infrastructure as code using CDK, asynchronous services over SQS, and Postgres (with VectorChord for vector search)
• Fluency with AI-assisted development: building with coding agents and LLM tools is part of your normal workflow
• Strong fundamentals in testing, observability, and debugging across distributed systems
• Nice to have: experience with small language models (SLMs), including fine-tuning, evaluation, or serving them in production
• Nice to have: experience close to AI/ML systems, such as model serving, retrieval, or evaluation harnesses
• Staffing, recruiting, or HR tech experience is a plus
