Senior Solutions Engineer, Post Sales at Junction

Healthcare is in crisis and the people behind the results deserve better. With more and more data coming from wearables, lab tests, and patient–doctor interactions, we’re entering an era where data is abundant. Junction is building the infrastructure layer for diagnostic healthcare, making patient data accessible, actionable, and automated across labs and devices. Our mission is simple but ambitious: use health data to unlock unprecedented insight into human health and disease. If you're passionate about how technology can supercharge healthcare, you’ll fit right in. Backed by Creandum, Point Nine, 20VC, YC, and leading angels, we’re working to solve one of the biggest challenges of our time: making healthcare personalized, proactive, and affordable. We’re already connecting millions and scaling fast. Short on time? TL;DR - You: A senior Solutions Engineer who has supported complex, API-first products and can independently run detailed technical conversations with both startup and enterprise engineering teams. - Ownership: Post-sales technical calls, onboarding customers through integration, owning technical collateral, and translating recurring customer blockers into structured feedback for Product and Engineering. - Salary: $160,000 - $200,000 + equity *The salary range shown is intentionally broad to reflect the range of skills and levels that we are open to for this role. - Location: Fully remote (EST timezone only) Why we need you We have more customers coming in than Product can support directly. Right now, we’re struggling to juggle building new features and providing great customer service to deeply technical customers. Customers come to us with detailed technical questions: API authentication, access models, architecture, integration patterns, device data flows, lab network coverage, and compliance requirements (HIPAA, SOC 2, BAAs). Product handles most of it because they have the context. That doesn’t scale. We’ve hired ahead on engineering, and several company priorities depend on Product having the time to properly design features and coordinate engineering work. If Product stays tied up in pre- and post-sales technical support, we ship fewer features — or ship the wrong ones. This role exists to change that. Within six months: - Product time on external calls should drop below 10%. - You should be able to independently handle the majority of customer technical conversations. - Product should have materially more time for product and engineering outcomes. What you’ll be doing day to day - Lead post-sales technical calls: explain the API, auth model, architecture, integration patterns, lab coverage, device data flows, and compliance posture - Be the technical voice in the room: handle deep technical questions, bringing in Product or Engineering only when necessary - Own onboarding through early integration: partner with customer engineers to get to first successful API calls and production launch - Troubleshoot edge cases quickly over Slack and live calls - Own Junction's technical collateral: docs, guides, decks, and segment-specific materials - Feed the roadmap: translate recurring blockers and feature gaps into structured input for Product and Engineering Requirements - You’ve worked in a customer facing role on a technical B2B product - You’ve supported an API-first platform and can explain authentication, access control, architecture, and integration trade-offs - You’ve independently led technical pre-sales conversations with both startup and enterprise customers - CTOs and engineers respect your depth of expertise - they never ask for another call with a member of the engineering team - You’ve been the primary technical contact through evaluation and early integration - You’ve owned onboarding, and fought for the best interests of the customer through implementation to launch - You’ve handled security and compliance work with customers, including questionnaires and reviews (HIPAA, SOC 2, BAAs) - You can troubleshoot integration issues live with customer engineering teams - You’ve written documentation, created videos and supported customer onboarding in a way that wows people You don’t need to tick every box to fit in here. If the problems we’re solving genuinely interest you and you know you can contribute, we’d love to talk. What this role isn’t - Not a ticket router. You’re aren’t here to direct tickets from customers to the relevant engineering team. Most challenges customers raise, you’re expected to fix yourself, or at least understand how we’ll solve it - Not an AE role. You won’t carry a quota, but your work will directly affect whether deals move forward and how quickly customers get live. - Not a scripted demo track. Customers will ask detailed questions about auth, architecture, compliance, and edge cases. You’ll need to handle those confidently. If you’ve supported complex, API-first products and regularly fielded detailed technical and security questions from customer engineering teams, this will feel familiar. How you'll be compensated - Salary: $160K - $200k + equity - Your salary is dependant on your location and experience level - Generous early stage options (extended exercise post 2 years employment) - Regular in person offsites, last were in Morocco and Tenerife - Bi-weekly team happy hours & events remotely - Monthly learning budget of $300 for personal development/productivity - Flexible, remote-first working - including $1K for home office equipment - 25 days off a year + national holidays - Healthcare cover depending on location Oh and before we forget: - Backend Stack: Python (FastAPI), Go, PostgreSQL, Google Cloud Platform (Cloud Run, GKE, Cloud BigTable, etc), Temporal Cloud - Frontend Stack: TypeScript, Next.js - API docs are here: [Upgrade to PRO to see link] - Company handbook is here [Upgrade to PRO to see link] with engineering values + principles Important details before applying: - We only hire folks physically based in GMT and EST timezones - more information here.
