About the Role
We are seeking a highly skilled and motivated Technical-Sales Engineer to join Mattermost as we enter the Japanese market. This is a high-impact, early-stage opportunity requiring a “player-coach” mentality with significant room for ownership, autonomy, and professional growth.
As the first technical hire in Japan and the Indo-Pacific region, you will not only lead technical demonstrations but also serve as a strategic partner to our sales team, directly shaping regional growth and ensuring customer success in high-trust environments.
Key Responsibilities
- Strategic Technical Leadership: Lead all regional technical activities, including pre-sales architecture, product demos, and deep-dive technical evaluations.
- Mission-Critical Deployment: Architect and deploy solutions within complex on-premise, air-gapped, and private cloud environments, ensuring operational resilience for defense and national security customers.
- Partner & Channel Enablement: Collaborate with system integrators (SIs), VARs, and distributors to build a sustainable technical network and contribute to the regional partner go-to-market plan.
- Stakeholder Management: Translate complex technical details into value propositions for audiences ranging from executive C-suite (General Officers) to frontline operational personnel.
- Product Advocacy: Act as a bridge between Japanese customers and our global product/engineering teams, representing local requirements to help build world-class, mission-ready software.
- Post-Sales Excellence: Support technical engagements for key accounts to ensure customers are achieving their specific mission outcomes and workflow automation goals.
Required Skills & Experience
- Industry Expertise: 10+ years of technical experience, specifically within the cybersecurity sector or high-growth SaaS/technology companies.
- Domain Knowledge: Proven experience serving defense, national security, or critical infrastructure customers.
- Infrastructure Mastery: Strong knowledge of closed cloud environments, on-premise deployments, and the technical/operational concepts utilized within secure sectors.
- Entrepreneurial Mindset: Experience in global startups is preferred; you must be an independent, creative problem-solver capable of negotiating technical “win-win” scenarios.
- Communication: Native Japanese language skills and strong English proficiency (reading/writing).
- Travel: Ability to travel based on business needs to support partner events, tradeshows, and customer sites (up to 50%).
Preferred Qualifications
- Active Security Clearance: Highly desired due to the nature of our mission-critical customer base.
- Forward-Thinking: Awareness of GenAI and its applications in secure collaboration.
- Education: Bachelor’s degree in a technical field or equivalent work experience.
