About the role
- You'll work directly with Bruce Kim (CTO / Co-Founder), who sets the technical bar and goes deep on the hardest problems, and Srinivas Njay (CEO), who is hands-on daily across product and engineering.
Responsibilities
- Own the technical win on all assigned enterprise opportunities - from discovery through proof of concept completion and executive sign-off - operating as a true co-seller alongside the AE, not a demo resource.
- Lead structured technical discovery on every assigned deal, uncovering integration complexity, organizational dynamics, and true evaluation criteria - and delivering a deal brief to the AE within 24 hours of each discovery call.
- Build and deliver tailored product demonstrations of interface.ai http://interface.ai's full platform - AI Phone Banking, Smart Discovery, Smart Transaction, and FLA/Orbit - mapped precisely to each prospect's stated pain and unstated anxieties, not a generic feature walkthrough.
- Design, own, and execute proof of concept engagements
- manage the technical evaluation end-to-end and drive to a documented technical win before commercial close.
- Co-own competitive strategy with the AE on displacement opportunities
- Build and maintain a reusable demo environment tailored to the credit union and community bank buyer persona, continuously refined with competitive intelligence and new product capability.
- Support V5→V6 migration conversations as a technical authority - speak credibly to platform architecture differences, data migration implications, and integration continuity for prospects evaluating during transition.
- Design, own, and execute proof of concept engagements; manage the technical evaluation end-to-end and drive to a documented technical win before commercial close.
- Co-own competitive strategy with the AE on displacement opportunities; know the incumbent's weaknesses, the customer's switching cost calculus, and interface.ai http://interface.ai's winning angles - and put them in writing after every closed deal.
Requirements
- Bachelor's degree in Computer Science, Engineering, or a related technical field.
- 4+ years in B2B SaaS, AI, or enterprise technology, with at least 3 years in a dedicated Solutions Engineer or pre-sales engineering role carrying direct ownership of the technical win.
- Proven track record in competitive displacement - has beaten an incumbent in a structured evaluation, not just sold into greenfield accounts.
- Familiarity with core banking integration patterns, telephony architecture, and API-based platform connectivity - directly relevant to the credit union and community bank buyer.
- Demonstrated career progression from a technical foundation - support, implementation, or TAM - into pre-sales, with a clear record of expanding deal complexity, product surface area, and vertical depth at each stage.
- Deep technical fluency in AI and NLU concepts - intent recognition, confidence thresholds, fallback design, model retraining - and the ability to speak credibly to these topics with both technical and non-technical audiences.
- Tailored demos of our product suite to help each financial institution with what their needs will be. Competition analysis, technical expert for POC.
- Up to 25% travel: trade-shows, conventions, customer visits
- Experience building and delivering custom POC environments and demo sandboxes
- engineering initiative beyond slide-deck SE work is a strong positive signal.
- Strong written communication skills: owns RFP and RFI responses, POC summaries, and technical proposals independently without requiring heavy AE or sales leadership support.
- Skill in using AI and productivity tools - including prompt engineering with generative AI - to build sharper demos, faster RFP responses, and more compelling technical narratives.
