Company mission
Thumbtack's mission is to help homeowners care for their homes, all the way from minor retouching to fundamental remodelling projects.
Role
Who you are
- 4+ years of experience in software engineering, application security, or cloud infrastructure security
- Practical experience with application security techniques such as threat modeling, secure design patterns, authentication and authorization, secrets management, and vulnerability remediation. Strong understanding of secure coding practices and common application security risks (e.g., OWASP Top 10)
- Experience securing cloud-native systems in AWS and/or GCP
- Ability to assess security risks and break down complex problems, reason about tradeoffs, make sound recommendations, and deliver practical, impactful solutions with guidance when needed
- Strong sense of ownership over assigned work, with the ability to execute independently and follow through
- Clear written and verbal communication skills, including the ability to explain security issues to engineers with varying levels of security expertise
- A growth mindset and interest in learning from more senior engineers and expanding depth in both application and cloud infrastructure security over time
What the job involves
- The Security Engineering team at Thumbtack is focused on enabling innovation at scale by making the secure path the easiest path. We believe strong security is not a blocker to velocity, but a force multiplier when it is designed into systems, platforms, and developer workflows from the start
- We partner closely with Product, Engineering, Platform, and Data teams to shape system design, guide architectural decisions, and evolve Thumbtack’s security posture as the company scales. Through collaboration, automation, and thoughtful tradeoffs, we help ensure Thumbtack can ship fast, innovate boldly, and maintain customer trust
- As Thumbtack scales and increasingly incorporates AI-powered features into our products and internal systems, security must evolve without slowing innovation
- The number of services, deployment patterns, and data flows continues to grow, and traditional approaches that rely heavily on manual reviews or after-the-fact controls do not scale to meet this need. Instead, the challenge is to design security into the system itself
- This means building secure defaults, paved paths, and reusable building blocks that product and engineering teams can adopt with minimal friction
- By embedding security directly into architectures, tooling, and infrastructure, we reduce cognitive load on engineers and enable teams to move quickly and confidently while meaningfully lowering risk
- Own and deliver application security work within defined projects or domains. Contribute to cross-functional security initiatives, executing clearly scoped pieces of larger efforts
- Identify, prioritize, and help remediate application security risks in partnership with engineering teams
- Apply secure-by-default patterns and approved architectures when designing or reviewing systems
- Support cloud infrastructure security by integrating security controls into CI/CD pipelines, IAM, networking, and runtime environments
- Partner with product and engineering teams to assess risk and recommend practical, risk-informed security improvements. Participate in application security design reviews and threat modeling for new and existing systems
- Write code, reviews, and documentation to address vulnerabilities and reduce recurring classes of issues
- Participate in security incident response and contribute to post-incident analysis and remediation
Our take
ThumbTack is a local services marketplace app that pairs customers with skilled professionals. Instead of simply searching for a professional, users provide ThumbTack with details of the job they need completing and the professionals then pitch their services to the potential customer using credits. ThumbTack makes its money by charging the professional for these credits.
It positions itself as something a little different in a saturated local services space that is dominated by companies like Angie’s List, TaskRabbit, Yelp, eBay, and Amazon. It also focuses on a broad range of professionals, from traditional home services like electricians and painters to photographers, personal trainers, and birthday party magicians.
The COVID-19 pandemic saw a boost in business for ThumbTack as more people stayed at home and made changes to their properties, increasing the demand for home professionals. In fact, after 2019, the company doubled in value to $3.2 billion with its 2021 raise. Since its 2024 funding round, its updated app has 30 new features, and the company is partnering with the likes of trade-powering platform and Unicorn ServiceTitan, indicating Thumbtack's sustained sway in the market.
