About Solutions Engineering at Promptfoo

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 (40%)

• 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 (30%)

• 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 (20%)

• 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 (10%)

• 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

What We're Looking For

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

• Translate ambiguous customer problems into concrete technical solutions

• Genuine interest in understanding why customers need things, not just what

Autonomy:

• Self-directed with minimal supervision

• Can prioritize across many concurrent workstreams

• Builds systems and documentation to scale yourself

Communication:

• Exceptional written and verbal skills

• Can present to technical and executive audiences

• Writes clear technical documentation

Nice-to-Haves

• Experience with LLM applications, AI security, or developer tools

• Background in application security or red teaming

• Previous product engineering experience (we hire engineers who love customers)

• Used Promptfoo before

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.

Apply

If this sounds like you: an engineer who loves working with customers, wants to shape product, and doesn't want to become a salesperson—we'd love to talk.
