Software Engineer - Security

Great customer support requires human agents and AI in perfect balance, and Assembled is the only unified platform that orchestrates both at scale. Companies like Canva, Etsy, and Robinhood use Assembled to coordinate their entire support operation — in-house agents, BPOs, and AI — in a single operating system. With AI Agents that resolve cases end-to-end, AI Copilot for agent assistance, and AI-powered workforce management that optimizes both human and AI capacity, Assembled helps teams deliver faster, better service while making smarter decisions about how to staff and automate. Backed by $70M from NEA, Emergence Capital, and Stripe, we're building the platform that makes AI and human collaboration actually work.

We’re looking for a software engineer to lead security engineering at Assembled. You’ll build infrastructure, systems, and processes that maintain the security and confidentiality of Assembled’s data, both for our AI agents product and our workforce management product. As we anticipate these products to continue growing rapidly in scale, we must ensure that our security infrastructure also evolves to meet industry standards.

This is a hands-on engineering role that involves writing and reviewing code on a daily basis, so strong programming fundamentals are required. By joining our Security team, you’ll have the opportunity to work on 0-to-1 problems across various domains within security: application, infrastructure, and data. This role engages especially closely with our Infrastructure team to ensure that we provide a secure and reliable platform to our customers and their data.

• Design and implement secure, scalable code at the application, platform, and infrastructure levels

• Perform security assessments, code audits, and design reviews

• Own the vulnerability management lifecycle end-to-end

• Create policies, processes, and tooling that enhance Assembled’s security posture

• Migrate our authentication system to an industry-standard identity provider, improving access control and auditability across our products

• Conduct a comprehensive review of our networking setup (e.g. VPCs, subnets, ingress/egress rules) and implement changes to align with cloud infrastructure security best practices

• Develop new data anonymization workflows in our analytics pipelines to enhance privacy protections while maintaining usability for internal teams

• Build and maintain automation to streamline security processes (e.g. access reviews, vendor security assessments, and security questionnaires) for both engineering and go-to-market teams

• Have deep expertise in a backend programming language (Golang and Python preferred), as well as security frameworks and libraries

• Have 5+ years of experience in security engineering, including 2+ years leading large scale, complex projects as an engineer or tech lead

• Have solid foundational knowledge of security engineering principles and technologies

• Have hands-on, technical expertise securing and managing cloud infrastructure

• Have experience leading your organization to comply with security standards and regulations such as SOC 2 and GDPR

• Generous medical, dental, and vision benefits

• Paid company holidays, sick time, and unlimited time off

• Monthly credits to spend on each: professional development, general wellness, Assembled customers, and commuting

• Paid parental leave

• Hybrid work model with catered lunches everyday (M-F), snacks, and beverages in our SF & NY offices

• 401(k) plan enrollment
