<h3>Job Description</h3><div>About Ease Health\n<p>Ease Health is building the AI-native operating system for behavioral health. Today, providers rely on fragmented systems across EHR, CRM, billing, scheduling, and documentation. This creates operational drag, staff burnout, and lost revenue. Ease consolidates these into a single platform powered by AI.</p>\n<p>We’ve raised $41M led by Andreessen Horowitz. We are growing extremely fast, partnering with leading behavioral health organizations across the country, and rapidly expanding both our product and team.</p>The Role\n<p>We’re hiring software engineers to build the product. You’ll own real parts of it end-to-end, work directly with the people using it, and ship fast.</p>\n<p>This is a product engineering role. We want engineers with good product instincts, people who care about what gets built, not just how it gets built. Behavioral health workflows are dense and specific, and we expect you to come up to speed on them quickly and become a real expert. That part matters as much as the code.</p>\n<p>We move fast. We work hard. We don’t trade off quality to do it.</p>\n<p>And the work matters. What you build gets used every day by clinicians treating people who are sick and need care. Behavioral health is one of the hardest, most under-served corners of medicine, and the software available to providers today is bad. Fixing that has real consequences for real patients.</p>What you’ll do\n<ul>\n <li>Own meaningful surface area of the product end-to-end</li>\n <li>Talk to behavioral health providers and turn what they need into software</li>\n <li>Make product decisions, not just execute against tickets</li>\n <li>Build with AI throughout the stack: LLMs, agents, automation across clinical workflows, intake, billing, and documentation</li>\n <li>Ship in days, not quarters</li>\n <li>Help shape how we hire, how we build, and where the product goes</li>\n</ul>Who you are\n<ul>\n <li>Strong engineer with sharp product instincts</li>\n <li>Fast learner. We want someone who jumps in, picks up the domain quickly, and becomes an expert in behavioral health workflows. That’s a big part of the job.</li>\n <li>Bias toward shipping. You’d rather have something in front of users this week than spend a month designing it</li>\n <li>Hungry for ownership. You want big scope and the autonomy that comes with it</li>\n <li>Willing to work hard. We’re building something that matters and we move accordingly</li>\n <li>Comfortable in ambiguity. The right path usually isn’t written down anywhere</li>\n <li>Candidates of all backgrounds welcome. No CS degree required, no minimum years of experience, no brand-name résumé needed. We care about what you can build.</li>\n</ul>Why this role\n<ul>\n <li>Work on software that actually matters to patients and providers</li>\n <li>Big scope and equity from day one</li>\n <li>Fast-growing, well-capitalized company, led by a16z</li>\n <li>Build AI-native software in a category that’s never had it</li>\n <li>Get in early enough that what you ship defines the product</li>\n</ul>\n<ul><li><br /></li></ul></div>

<h3>Job Description</h3><div><p>Our client is hiring a full-stack Software Engineer to help build their investment analytics platform. You'll own significant pieces of the infrastructure, make real architectural decisions, and work directly with the business teams who depend on what you build. You'll identify problems, design solutions, and ship — often in the same week. You need to be comfortable with ambiguity, confident making judgment calls, and energized by work where there's no established playbook.</p>\n<p><br /></p>\n<p><strong>RESPONSIBILITIES:</strong></p>\n<ul>\n <li>Build and own the platform — design and maintain the application infrastructure, API layer, and shared services that power the Analytics Engine end-to-end. Microsoft Azure experience is preferred.</li>\n <li>Set the technical foundation — make early architectural decisions that will shape how the platform scales; know when to move fast and when to get it right.</li>\n <li>Develop full-stack applications that surface ML insights and advanced analytics through intuitive, responsive interfaces built in React and TypeScript. C# and SQL experience is valuable.</li>\n <li>Improve developer velocity — own the build, deploy, and testing pipeline and continuously reduce friction for the team.</li>\n <li>Integrate AI-native workflows — build tools, prompts, and evals that put real analytical leverage in the hands of investment teams.</li>\n <li>Work directly with stakeholders — engage with investment, asset management, and capital markets teams to understand problems, gather feedback, and iterate without waiting for someone else to translate.</li>\n</ul>\n<p><br /></p>\n<p><strong>QUALIFICATIONS:</strong></p>\n<ul>\n <li>5+ years of full-stack development experience, <strong>including time in an early-stage or 0→1 environment (ideally fintech, etc)</strong></li>\n <li>Proven ability to ship <strong>end-to-end</strong> independently — from scoping a problem to deploying production code — without needing a designer, PM, or architect to unblock you</li>\n <li>Experience shipping LLM-native features or applications in production</li>\n <li><strong>Expert-level React skills: modern patterns (hooks, context, suspense), performance optimization, and component architecture</strong></li>\n <li><strong>Strong backend proficiency in Python or Node.js; fluent in designing and maintaining scalable APIs</strong></li>\n <li>Must have worked on a <strong>data science or predictive analytics</strong> tool/product</li>\n</ul>\n<p><br /></p>\n<p><strong>PREFERRED:</strong></p>\n<ul>\n <li>Experience building ML-powered application workflows and integrating data science outputs</li>\n <li>Familiarity with MCP or production LLM integrations</li>\n <li>Background at an AI-native company or in a product-focused founding environment</li>\n <li>Experience in real estate, finance, or other data-intensive industries</li>\n</ul></div>
