This role sits at the intersection of pre-sales engineering, telephony architecture, and enterprise contact center strategy. You will act as a trusted advisor to enterprise prospects and customers, guiding them through complex, ambiguous voice deployment conversations—from SIP trunking and call routing to media handling and real-time transcription—ensuring Decagon integrates seamlessly into their existing contact center platforms while meeting latency, reliability, and compliance requirements.

Role Mission Own, lead, and scale Discovery & Framing at Defense Unicorns—help customers identify and clearly define the mission problems that matter, quantify their impact, establish what success looks like, and create the clarity needed to determine the right path forward. The Head of Discovery & Framing will lead the highest-priority customer engagements, establish the D&F methodology and quality standard, and build the team required to deliver the discipline at scale. The Role Defense Unicorns is creating a dedicated Discovery & Framing function to improve how we understand customer problems before moving into solution design. This is a senior, hands-on strategy role for someone who knows how to walk into an ambiguous customer situation, ask the questions others miss, separate symptoms from root causes, and turn a complex discussion into a clear and measurable mission problem. Trust is built by knowing the customer's mission intimately—its language, operating tempo, constraints, failure modes, stakeholder pressures, and consequences of getting it wrong. The Head of D&F must be equally comfortable facilitating a working session with senior customer leaders, interviewing operators and technical stakeholders, analyzing what was learned, and producing a concise executive-quality output afterward. This is not a traditional sales role, product presentation role, or technical discovery role. Operating principle: Help the customer define and measure the right problem before asking them to choose a solution. What You Will Own Lead Discovery & Framing Engagements Prepare for and personally facilitate high-value D&F engagements with customer executives, mission leaders, operators, technical stakeholders, acquisition leaders, and other key participants. Lead the most strategic, complex, or ambiguous engagements while developing additional D&F practitioners to handle increasing volume. Build the Discovery & Framing Function Establish the D
