AdeptID • Boston, MA

About The Position

AdeptID is building the AI-first Talent Company to solve talent shortages at scale. Our talent matching technology is embedded in ATS, HCM, and job boards, enabling workflows across recruiting, job search, and career navigation. Our API-first strategy does more than create revenue: it generates training data, strengthens our models, and advances our mission to match every person to the right job.
We are now applying that same technology, data, and network to build an AI-first staffing business, starting in healthcare, designed to deliver faster placements and stronger matches. Many ATS platforms have tried to build their own search and match, only to learn it is slower, costlier, and riskier than expected: AdeptID has shown early partners that our APIs are better, safer, faster, and cheaper than building in-house.
Our API business and our staffing business reinforce each other: the same core software and data power both, the API business sharpens the matching technology, and the staffing business puts it to work placing people. Backed by leading investors, we have a healthy balance sheet and are in an ambitious growth phase: investing in technology, acquiring staffing businesses, and building the team that will define the next generation of talent matching.
The Role
We are hiring a Senior Software Engineer to build the core software behind our talent matching: the services that search, score and rank candidates and the APIs that deliver matches to some of the largest HR technology organizations in the world, and to our own staffing business. Data Science owns the matching and language models; you own the production services, serving layer, and APIs that put them to work reliably and at low latency. This is a hands-on role for an engineer who builds with modern AI tooling by default, on a small and growing team.

Requirements

• 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 Haves

• experience with small language models (SLMs), including fine-tuning, evaluation, or serving them in production
• experience close to AI/ML systems, such as model serving, retrieval, or evaluation harnesses
• Staffing, recruiting, or HR tech experience is a plus

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
