Job Description
Reports To: Director of Data &amp; AI Product Partners With: Product, Engineering, Data Science, and Growth teams Salary Range: $80,000–$120,000 per year Location/Schedule: Downtown Boston; 2–3 days/week in-office
About AdeptID
AdeptID is building the AI-first Talent Company to solve talent shortages at scale. Our talent matching APIs (Candidate Match, Candidate Search, Job Search) are embedded in ATS, HCM, and job boards, powering 8–10 million job recommendations per month.
This API-first strategy generates training data, strengthens our models, and advances our mission to match every person to the right job. 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 to implement, and far cheaper than repeated in-house initiatives.
Role Overview
<ul>
<li>Own end-to-end enterprise implementations of our AI platform: gather requirements, develop POCs, lead onboarding, and drive customer value from initial setup to launch and beyond.</li>
<li>Be the primary technical and product partner for a select group of high-value customers, ensuring their success while advocating for their needs internally</li>
<li>Serve as the voice of the customer to the product team, helping to shape our roadmap and create features that solve real-world hiring and talent matching challenges.</li>
<li>Support the sales process by developing prototypes and demonstrating product value in high-stakes client conversations.</li>
<li>Innovate and document processes that make future implementations easier, faster, and more impactful.</li>
<li>Build hands-on expertise with production-grade AI systems, gaining experience with APIs, data integration, and real-world model deployment.</li>
</ul>
What You Bring
<ul>
<li>5+ years of relevant experience. That might be in software implementation, solutions or sales engineering, product enablement, technology consulting, or another relevant function.</li>
<li>Exceptional communication skills and the ability to build trust with both technical and non-technical stakeholders at a range of seniority levels.</li>
<li>Proficiency in Python. You'll be working with dataframes, JSON files, RESTful APIs, Snowflake databases, and more - mostly via Jupyter Notebooks in VSCode. You won't be building production software, but will be analyzing large volumes of data and developing POCs.</li>
<li>An ability to "figure it out" - our team members use ChatGPT, tutorials, and other resources to learn new skills daily.</li>
<li>Strong technical curiosity and eagerness to grow expertise in AI and scalable product solutions.</li>
<li>Excellent problem-solving skills, with experience translating business needs into technical outcomes.</li>
<li>Self-motivated and adaptable, thriving in a fast-paced, early-stage environment</li>
<li>Experience in HR tech is a plus.</li>
</ul>
Why Join Now
<ul>
<li>Adept's API business already powers millions of matches each month.</li>
<li>Early partners have validated that Adept's matching is better, faster, safer, and cheaper than in-house efforts.</li>
<li>We are combining our API business with an AI-first staffing business, creating a unique position in the market: infrastructure + direct placement at scale.</li>
</ul>

Job DescriptionAbout Yuma AI:
Yuma is building a next-generation orchestration platform that deploys autonomous AI agents dedicated to customer support in e-commerce. We already support 150+ paying merchants and help them automate up to 80% of their customer tickets freeing human agents for higher-value conversations.
Founded by Guillaume Luccisano (3rd-time YC founder) at the end of 2022, Yuma is one of the leaders in the AI Support Automation space with 10+ consecutive months of double-digit growth. 
We are now a team of 30 passionate and ambitious people based between Paris, Barcelona and Boston and have grown revenue 5x in 2025. We aim to repeat this trajectory in 2026. The scale-up phase is fully underway. 🚀
About the Role : 
This is a foundational role. You will be joining Yuma as one of the core engineers on a tight, high-performing team of 5. We move fast, iterate aggressively, and care deeply about product quality and user value.
Over the past two years, we’ve built an impressive amount of product surface area, AI systems, and automation. Yet what lies ahead is even bigger. As we scale our platform, models, and AI agents, your work will have a direct and immediate impact on the experience of thousands of users.
This role goes far beyond classical backend development. You will work across the full product lifecycle: new features, A/B tests, model integrations, AI agent pipelines, and performance optimization. If you enjoy working at the intersection of backend engineering, product iteration, and applied AI, you will thrive here.

Backend Engineering:
<ul>
<li>
Architect, build, and scale large Ruby on Rails applications
</li>
<li>
Own major systems within our Rails API, including performance, reliability, and maintainability
</li>
<li>
Manage PostgreSQL at scale: schema design, indexing, performance diagnostics
</li>
<li>
Maintain and optimize Redis + Sidekiq pipelines for high-throughput workloads
</li>
<li>
Lead backend-heavy feature projects, from design to deployment 
</li>
</ul>
AI / LLM Systems:
<ul>
<li>
Integrate, evaluate, and iterate on LLM providers and models
</li>
<li>
Design systems that manage non-deterministic model outputs safely and predictably
</li>
<li>
Build and own A/B tests, eval pipelines, and agentic workflows
</li>
<li>
Optimize for latency, reliability, and cost across LLM-heavy features
</li>
<li>
Contribute directly to prompts, agents, and AI system architecture 
</li>
</ul>
Product &amp; Full-Stack Contribution :
<ul>
<li>
Collaborate tightly with founders and engineers to define product requirements
</li>
<li>
Jump into frontend (Next.js/React) when needed to ship features end-to-end
</li>
<li>
Run rapid product iterations: fast feedback loops, experimentation, data-driven decisions
</li>
<li>
Maintain a high bar for product quality while optimizing for speed of execution 
</li>
</ul>
The Ideal You
<ul>
<li>
You have 5–10+ years of experience building and scaling production Rails applications
</li>
<li>
Rails has no secrets for you : you know how to ship quickly and safely
</li>
<li>
You are pragmatic: you make thoughtful trade-offs that maximize user value and iteration speed
</li>
<li>
You naturally take ownership and thrive in high-velocity environments
</li>
<li>
You have recent, hands-on experience with LLMs and already use AI in your day-to-day workflow
</li>
<li>
You’re comfortable navigating ambiguity, experimenting, and working with non-deterministic systems
</li>
<li>
You can contribute across the stack when needed (backend-first, but not backend-only)
</li>
<li>
You deeply care about product quality, speed, and delivering a great user experience
</li>
</ul>

The Alternative You : 
If you're still early in your career but see yourself becoming the engineer described above within the next 2–3 years, don’t hesitate. We consistently leave room for raw talent and high potential, especially for people who learn fast, care deeply, and want to grow.

Why Yuma?
<ul>
<li>
High impact with ownership from day one : join a small, international engineering team where every feature you ship and every solution you design is directly visible in production.
</li>
<li>
Competitive compensation based on experience and stock options
</li>
<li>
Fast growth = fast learning curve : in this hybrid engineering role, you’ll quickly gain exposure to AI, product iteration, customer workflows, and cross-functional problem-solving
</li>
<li>
Work closely with founders and product/engineering leadership : your ideas and your ownership will directly influence the roadmap.
</li>
<li>
A culture of ownership, transparency, and continuous improvement : we move fast, iterate constantly, and empower people to grow
</li>
</ul>

<h3>Job Description</h3>
Job Description
At Kindbridge Research Institute (KRI), we are pioneering work in a space that's still taking shape—gambling-related mental health. As a non-profit at the intersection of research, behavioral health, and community well-being, KRI is leading efforts to better understand gambling behaviors and their impact on vulnerable populations such as veterans, service members, and young adults. Through partnerships with researchers, universities, and public health systems, we deliver data-driven solutions and outreach strategies that promote awareness, prevention, and access to care.
We're seeking a Project Manager for the Research and Education Collaborative (REC) to help KRI turn data into meaningful change and improve lives across Massachusetts. In this role, you will be at the center of a statewide collaborative, transforming research into accessible, real-world solutions for communities disproportionately impacted by structural inequities. You will guide REC's daily operations with purpose and clarity, build powerful cross-sector partnerships, and help bring the OPGS Data to Action Framework to life—ensuring that evidence becomes action, and action becomes impact.
In year one, this role will be fully dedicated to the Massachusetts REC initiative. In year two, it will shift to a 50/50 split between the MA program and additional KRI projects as they arise.
Why This Role Matters:

<li>Manage REC committees, including scheduling, communication, materials, and follow-up</li>
<li>Oversee the Department of Public Health documentation, reporting, billing, and compliance requirements</li>
<li>Organize and track program deliverables, timelines, and stakeholder responsibilities</li>
<li>Engage higher education partners, healthcare systems, nonprofits, and state agencies to strengthen cross-sector engagement and collaboration</li>
<li>Proactively follow up with partners to keep projects moving forward</li>
<li>Prepare program updates and reports for leadership, state partners, and funders</li>
<li>Report to the Director of Programming and communicate progress, challenges, and needs</li>
<li>Manage a small team of administrators and research analysts</li>
<li>Identify risks, propose solutions, and drive project success with strong organization and problem-solving</li>
<li>Stay up to date on best practices in behavioral health, gambling harm, and prevention programming, and bring new ideas forward</li>
<li>Contribute to a collaborative, inclusive work environment built on professionalism, integrity, and accountability</li>
</ul>
Qualifications:
<ul>
<li>Bachelor's degree in public health, social sciences, business administration, nonprofit administration, or a related field</li>
<li>5+ years of experience managing programs or projects, ideally in nonprofit, government, healthcare, research, or academic environments</li>
<li>Experience coordinating multi-stakeholder committees, grant-funded programs, or public health initiatives</li>
<li>Strong skills in documentation, reporting, and communicating with state agencies (Massachusetts DPH experience is a plus)</li>
<li>Familiarity with behavioral health, addiction, social determinants of health, or public health surveillance; knowledge of gambling-related issues is a bonus</li>
<li>Excellent organizational, communication, and problem-solving abilities, with the confidence to work independently and collaboratively</li>
<li>Comfort navigating ambiguity with a proactive, solutions-oriented mindset</li>
<li>Familiarity with public health, mental health, or gambling-related issues a plus</li>
