Tenchi is a Cyber Security company building innovative technology focused on Third-Party Cyber Risk Management for businesses. Founded by serial entrepreneurs and supported by solid institutional investors, we are driven to disrupt this fast-growing industry.

Tenchi was created to tackle a real challenge: companies often face security risks because their third-parties don’t maintain the same level of cyber protection. This gap leaves even the largest organizations potentially vulnerable to incidents they can’t directly control. That’s exactly where we step in.

Our TPCRM SaaS solution, Zanshin, is the only global TPCRM solution that offers both inside-out and outside-in visibility - combining external attack surface monitoring with automated, continuous, and non-intrusive assessments of cloud infrastructure (IaaS, PaaS, SaaS) and security controls.

Key Responsibilities:

  • Translate product requirements documents (PRDs) into detailed design documents.
  • Design, develop, and maintain user interfaces for web applications.
  • Write clean, efficient, and well-structured code using modern TypeScript frameworks (preference for Svelte).
  • Collaborate with designers, backend engineers, and product managers to deliver exceptional user experiences.
  • Optimize web applications for performance and security (XSS, CSRF mitigation techniques).
  • Stay up-to-date with the latest frontend development trends and technologies.

Requirements

  • Strong proficiency in HTML, CSS, and TypeScript.
  • Experience with at least one modern TypeScript framework (Angular, React, Vue, Solid, Svelte, Qwik).
  • Understanding of responsive web design and cross-browser compatibility.
  • Ability to write clean, maintainable, and efficient code.
  • Excellent problem-solving and debugging skills.
  • Strong communication and collaboration skills.
  • Ability to translate product requirements into detailed design documents.

Bonus Points:

  • Knowledge of one testing framework (Jest, Cypress, Playwright).
  • Experience with performance optimization techniques.
  • Contributions to open-source projects.

If you're a motivated and skilled Frontend Engineer who is passionate about creating beautiful and functional web applications and can effectively translate product requirements into design documents, we'd love to hear from you!

Tenchi Security

View Company Profile

Tenchi Security (operating under tenchisecurity.com) is the premier, enterprise-grade Third-Party Cyber Risk Management (TPCRM) platform, software-defined supply chain security innovator, and cloud posture orchestration powerhouse engineered to serve as the definitive, high-velocity vendor risk reduction, automated compliance monitoring, and structural vulnerability assessment layer for multinational enterprises, massive banking groups, and critical digital ecosystems globally. The company completely eliminates the severe systemic friction of modern cloud supply chain risk—where corporate security units lose vital defensive momentum to manual, non-standardized third-party questionnaires, point-in-time annual compliance audits, and unvetted exposure silos outside their direct network boundaries—by deploying an advanced, multi-tenant risk reduction platform known as Zanshin. Moving far beyond traditional, passive external-only security scanners or rigid, antagonistic auditing models, Tenchi Security natively unifies automated inside-out cloud testing pipelines (linking with continuous IaaS, PaaS, and SaaS telemetry), outside-in attack surface mapping, over 1,000 continuous automated security checks, and real-time vendor remediation workflows into a single high-availability defense workspace. Protecting major financial networks, telecommunication conglomerates, and institutional systems across Latin America and global markets—including powerhouses like Bradesco, Cielo, XP Investimentos, BTG Pactual, B3, and Telefónica—the infrastructure monitors multi-tenant risk baselines with production-hardened engineering precision. Backed by an elite $7 million Series A financing matrix co-led by Bradesco, L4 Venture Builder, and Accenture, the organization maintains a highly distributed, 100% remote global engineering structure. Under the hood, its technology core utilizes sophisticated data pipelines (leveraging PySpark and Python), non-intrusive APIs, and secure multi-cloud access loops built to provide mutual, cooperative visibility for both first-party enterprises and third-party vendors without introducing new attack vectors or reducing operational business velocity. What sets Tenchi Security apart is its uncompromising dedication to replacing passive, compliance-driven risk acceptance with absolute proactive remediation agility, enforceable supplier accountability, and real-time ecosystem clarity; by bridging the gap between performance-intensive low-level technical infrastructure configuration and the collaborative security demands of modern interconnected business, the enterprise remains the definitive cornerstone of modern algorithmic third-party defense and global infrastructure transformation.
