Yet vulnerabilities threaten its integrity, security, and resilience. We are on a mission to secure the world's software. depthfirst is building intelligence to detect and remediate critical software vulnerabilities. We are training and scaling security AI agents to discover zero-day vulnerabilities across large customer codebases and popular open-source software. Our founding team brings deep expertise in data, infrastructure, security, and AI, with leaders from DeepMind, Databricks, Square, and Faire. We're looking for thoughtful, driven people excited to work at the intersection of AI, Security, and Infrastructure. ## About This Role We're looking for an exceptional Senior Solutions Engineer to help drive depthfirst's growth across Asia Pacific & Japan (APJ). This is a high-impact, customer-facing opportunity to play a foundational role in expanding our regional presence, partnering with some of the world's most sophisticated enterprises, and helping organizations transform how they secure software with AI. You'll own the technical sales motion for strategic and enterprise customers, from initial discovery and solution design through proof of value, technical validation, and executive alignment. You'll work directly with CISOs, security leaders, and engineering teams to understand complex security challenges, demonstrate the differentiated value of depthfirst's platform, and guide customers through successful technical evaluations. As an early member of our APJ go-to-market team, you'll have the opportunity to help shape our regional technical strategy, establish scalable evaluation processes, and build trusted relationships with customers and partners. We're looking for someone who combines deep technical expertise with strong commercial instincts, exceptional communication skills, and an entrepreneurial mindset. You're excited about this role because you will… - Own and lead complex technical sales engagements across APJ, partnering with Account Executives to support strategic enterprise opportunities from discovery through technical validation and close. - Serve as a trusted technical advisor to CISOs, CTOs, Security leaders, and Engineering teams, helping customers understand how AI-native security can transform their application security programs. - Design, execute, and lead sophisticated proofs of value (POVs), establishing clear success criteria tied to vulnerability detection quality, false positive reduction, remediation speed, and measurable business outcomes. - Demonstrate how depthfirst differentiates from traditional SAST, SCA, and application security solutions through contextual code understanding, reachability and exploitability analysis, and AI-driven vulnerability discovery. - Work hands-on within customer development environments, including source code repositories, CI/CD pipelines, and developer workflows, to ensure seamless technical evaluations and adoption. - Partner with enterprise sales teams to develop account strategies, navigate complex technical buying committees, overcome objections, and accelerate deal progression. - Translate complex technical findings into compelling business value and executive-ready presentations for senior security, engineering, and business stakeholders. - Build strong relationships with regional customers, technology partners, and security communities to help establish depthfirst's presence and credibility across APJ. - Act as the voice of the customer, collaborating closely with Product, Engineering, and Research to share technical feedback, identify emerging requirements, and influence product direction. - Help build and scale our global Solutions Engineering function by developing repeatable demo environments, evaluation frameworks, technical playbooks, and best practices. -

Strong technical foundation in application security, vulnerability management, secure software development, or related cybersecurity disciplines. - Deep understanding of modern software development workflows, source code management, CI/CD systems, and developer tooling. - Experience leading complex enterprise technical evaluations, proofs of concept, or proofs of value, including defining success criteria and demonstrating measurable customer outcomes. - Ability to engage confidently with both highly technical practitioners and senior executive stakeholders, translating complex security concepts into clear business value. - Experience supporting enterprise customers across Australia and/or the broader APJ region, with an understanding of regional customer expectations and buying dynamics. - Strong problem-solving skills and the ability to troubleshoot technical challenges within customer environments. - Experience collaborating closely with enterprise sales teams to develop technical account strategies, navigate complex sales cycles, and support successful commercial outcomes. - Comfortable operating independently in a fast-paced startup environment, with the ability to build processes, manage competing priorities, and thrive in ambiguity. - Excellent communication, presentation, and relationship-building skills. - Genuine curiosity and enthusiasm for AI, cybersecurity, and emerging technologies. - Based in Australia, with willingness to travel across Australia and the broader APJ region as needed. ## Nice to Have - Hands-on experience with application security tools, including SAST, SCA, DAST, or other vulnerability detection technologies. - Familiarity with common application vulnerabilities, exploitation techniques, and secure coding practices. - Experience with cloud infrastructure, containers, Kubernetes, and modern development environments. - Proficiency in one or more programming or scripting languages, such as Python, JavaScript, Go, or Java. - Experience supporting a new market or regional expansion within a high-growth technology company. - Background in developer-focused, cloud security, or AI-powered security products. ## What We Offer -

Backed by leading investors in AI, security, and software. - **Growth Signals**: 33 employees (366.7% YoY growth); 11 active job postings; claims 8x more true positives and 95% fewer false positives vs. leading tools; 90% of fixes accepted by developers; $5M in platform credits offered to open source maintainers via the Open Defense Initiative. ## Competitive Advantages - **AI-native context-aware reasoning** – The platform understands code, business logic, and infrastructure to find complex vulnerabilities (including business logic flaws and chained exploits) that siloed tools miss. - **Extremely low false positives and high fix acceptance** – 95% false positive reduction and 90% developer-accepted fixes create trust and productivity. - **Founding team** – Built security at Cash App/Faire, infrastructure at AWS/Databricks, and AI research at Google DeepMind (contributions to Gemini, AlphaDev, Nature publications). - **Continuous autonomous verification** – After each fix, the same attack is replayed in the running application; vulnerabilities are only closed when exploitation fails, not when code changes. ## Strategic Focus - Advancing AI agents for security through reinforcement learning (training vulnerability discovery agents, e.g., dfs-mini1 model). - Scaling enterprise adoption and expanding the Open Defense Initiative to secure widely deployed open source projects. - Building a research-driven applied AI lab focused on software security. ## Why Work Here - **Culture**: Positioned as an "applied AI lab" at the frontier of security and AI research. Team members come from top companies like Databricks, Meta, Google DeepMind, Faire, and Notion. - **Work policy**: On-site in San Francisco (multiple offices, including 250 Montgomery St and 1 Sutter St). - **Open roles**: 11 positions across Engineering (Backend, Product, Security, Research), Sales (Account Executive, SDR, Solutions Engineer), Product Design, and Business Operations. - **Notable perks**: Not explicitly detailed but typical for well-funded Series B startups; equity, competitive compensation, and the chance to work on cutting-edge autonomous security in a rapidly growing team. ## Sources 1.
