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 startup and enterprise engineering teams.
• Ownership: Pre and 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
• * 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, Product spends 30–40% of their time on external calls.

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 pre-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 as a Solutions Engineer, Sales Engineer 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
• You have experience selling to engineering-heavy buyers
• You’ve been the primary technical contact through evaluation and early integration
• You’ve onboarded customers from kickoff through implementation and production 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 created and maintained technical documentation and collateral used in sales and onboarding

Nice to have

• Experience in healthcare, diagnostics, life sciences, fintech, or another regulated, technically complex domain
• Experience at Seed–Series C B2B SaaS companies

What this role isn’t

• Not a lab integrations role. You won’t be the person building or owning lab-facing integrations work.
• Not only pre-sales. You’ll be involved before and after the deal — especially through onboarding and early integration.
• 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.
