Director of Technical Marketing

Silith is a fabless chip design company, established in 2021, developing silicon photonics interconnect solutions for the world's leading AI hyperscalers, semiconductor companies, and transceiver companies. Our technology helps build the AI data centers of tomorrow, with a product portfolio spanning scale-up, scale-out, and scale-across interconnects. As we grow our presence and build out our commercial organization, we're looking for people who want to help bring this technology to the world's most demanding infrastructure.

Position Summary
The Director, Technical Marketing will own the technical narrative that supports Silith's commercial growth — translating silicon photonics technology and product capabilities into compelling, credible positioning for hyperscalers, semiconductor companies, and OEMs. This person will sit at the intersection of Engineering, Product, and Sales/BD, building the technical content, competitive analysis, and customer-facing materials that move design win conversations forward. The role requires someone equally comfortable in a deep technical review with a customer's optical engineering team and on stage presenting Silith's roadmap at an industry conference.

Key Responsibilities
Technical Positioning & Messaging

Develop Silith's core technical narrative and value proposition across silicon photonics, optical interconnect, and AI infrastructure applications

Translate complex technical differentiation (e.g., modulator performance, integration architecture, packaging) into clear, customer-relevant messaging

Own technical positioning against competitors and alternative technology approaches

Tailor messaging by customer segment — hyperscalers, semiconductor companies, and OEMs each require a different technical story

Partner directly with Sales, BD, and the CRO on strategic account engagements, providing technical depth in customer meetings and design review discussions

Build account-specific technical presentations, white papers, and proof points that support the Challenge ? Solution ? Validated Result narrative used with technical buyers

Support technical due diligence requests from prospective customers, including data sheets, performance benchmarks, and application notes

Work with Engineering to translate lab results and simulation data into externally shareable proof points

Track competitor product roadmaps, technical claims, and market positioning across the silicon photonics and optical interconnect landscape

Produce competitive battlecards and technical comparison materials for use by Sales and BD

Monitor customer-facing technical trends (e.g., CPO, NPO, coherent, IM-DD) and translate implications into positioning updates

Brief executive leadership on competitive technical developments that could affect deal strategy

Own the technical content roadmap: data sheets, application notes, white papers, technical blog posts, and presentation decks

Ensure technical accuracy and consistency of messaging across all customer-facing materials

Develop reusable technical frameworks and templates that scale across the sales organization

Manage technical review and approval process with Engineering and Product before external publication

Industry Presence & Thought Leadership

Represent Silith at industry conferences and trade shows (e.g., ECOC, OFC) through speaking engagements, technical demos, and customer meetings

Build relationships with industry analysts, press, and standards bodies relevant to optical interconnect and silicon photonics

Support technical PR and analyst briefing efforts in coordination with executive leadership

Identify speaking, publication, and demonstration opportunities that build Silith's technical credibility in target markets

Cross-Functional Collaboration

Serve as the primary technical marketing liaison between Engineering, Product, and the commercial organization

Provide customer and market feedback to Product and Engineering to inform roadmap prioritization

Support pricing and positioning discussions with technical context on performance trade-offs and competitive benchmarks

Work with the VP of Sales Programs & Operations to ensure technical content aligns with design win funnel stages

Required Qualifications

10+ years of experience in technical marketing, applications engineering, or product marketing in semiconductor, optical communications, or related technology markets

Strong technical foundation in photonics, optical communications, or high-speed semiconductor design — able to engage credibly with customer engineering teams

Track record developing technical content and messaging that supports complex, long-cycle B2B sales

Experience presenting to technical and executive audiences, including at industry conferences

Strong writing skills with the ability to translate deep technical detail into clear, persuasive material

Comfortable working cross-functionally across Engineering, Product, Sales, and BD in a fast-moving organization

Preferred Qualifications

Direct experience with silicon photonics, optical interconnect, CPO/NPO architectures, or coherent/IM-DD technologies

Experience marketing to hyperscalers, semiconductor companies, or networking OEMs

Existing relationships with industry analysts, press, or standards bodies in optical/photonics markets

Background in applications engineering or field engineering prior to moving into marketing

Advanced technical degree (MS/PhD in Electrical Engineering, Photonics, or related field) preferred
