About the Role
You're an engineer first who happens to work directly with customers—not a salesperson who can code. You’ll be the bridge between prospects, customers, and our product team - jumping on technical calls daily, unblocking POCs, and turning field insights into product improvements.
Solutions Engineers at Promptfoo:
Write production-quality code (POCs, integrations, tools)
Architect solutions with customers / security teams
Shape our product through direct feedback to Engineering
Report to Engineering (VP of Engineering), not Sales
This is not a support role. This is not a sales role. This is an engineering role with deep customer exposure.
What You'll Do
Craft & Quality
Build: Production-quality POCs, integration examples, and demo environments
Code: Create reusable tools, scripts, and frameworks that scale customer success
Debug: Deep-dive on customer technical issues alongside their engineers
Architect: Design reference architectures for enterprise deployment patterns
Output should be demo-quality code, not throwaway prototypes
Customer Engagement
Technical deep-dives: Run architecture sessions and workshops with customer engineering/security teams
POC ownership: Lead hands-on proof-of-concept implementations (you're coding, not just presenting)
Strategic accounts: Own the technical relationship with 2-3 enterprise customers deeply
Technical escalations: Be the "break glass" expert for complex technical challenges
Product Feedback Loop
Aggregate: Collect, synthesize, and prioritize technical feedback from the field
Influence: Present customer insights to Product Engineering—your input shapes the roadmap
Documentation: Identify and close gaps in docs, APIs, error messages, DX
Customer Zero: Stress-test new features before they ship, write the first integrations
Team Enablement
Playbooks: Document best practices for POCs, workshops, deployments
Cross-training: Help AEs handle basic technical conversations independently
Quality bar: Review customer-facing technical deliverables
Hiring: Help define the bar as the Solutions Engineering team grows
Who You Are
Must-Haves
Engineering Depth:
Strong coding skills in JavaScript/Typescript and/or Python - you can write and ship production code
Comfortable with Docker, Kubernetes, and enterprise infrastructure
Can architect solutions and go deep on performance, security, and systems design
Debugging complex issues is satisfying, not frustrating
Customer Orientation:
Peer-level technical conversations with customer engineers, architects, and security leads

What This Role Is Not
To be explicit:
Not Sales Engineering: You don't report to Sales. You're not measured on deals closed. You're not doing demo theater.
Not Technical Support: You're not frontline support. You're building solutions alongside customers.
Not Solutions Consulting: You're not scoping billable engagements. You're an engineer who happens to work with customers.
Why This Role Is Unique
You're an engineer, treated like an engineer. You’ll report to the VP of Engineering, have an engineering career path, and have a comp structure that matches engineering. This is not sales.
High signal, low noise: You’ll work with enterprise security/engineering teams on real problems. You’re not doing 50 shallow demos a month - you’re doing 5 deep engagements.
Product influence: You will have a direct weekly sync with Engineering leadership. Your field insights shape the roadmap. You can (and should) contribute code to the product.
Cutting edge of AI: AI security is brand new—you're defining best practices. Work with how leading companies secure their AI.
