Assembled builds the infrastructure that underpins exceptional customer support, empowering companies like CashApp, Etsy, and Robinhood to deliver faster, better service at scale. With solutions for workforce management, BPO collaboration, and AI-powered issue resolution, Assembled simplifies the complexities of modern support operations by uniting in-house, outsourced, and AI-powered agents in a single operating system. Backed by $70M in funding from NEA, Emergence Capital, and Stripe, and driven by a team of experts passionate about problem-solving, we’re at the forefront of support operations technology.
The RoleWe’re looking for a software engineer with experience in building and operating infrastructure at scale. You’ll take ownership of all systems that power Assembled’s AI agents (Assist) and workforce management products. Both of these have been rapidly growing in scale: Assist has grown 5x in just 3 months to millions of ARR, with a strong pipeline of deals for even more growth; our workforce management product previously only served customers with hundreds of support agents, but now serves large enterprise customers with tens of thousands of support agents.
By joining our Core Infrastructure team, you’ll have the opportunity to work on many 0-to-1 problems that span a breadth of infrastructural components. This role engages cross-functionally with product, security, and support to ensure we’re delivering a scalable, reliable platform that can run wherever our customers need our technology most.
Some projects owned by the Core Infrastructure teamKubernetes cluster: Our servers (e.g. main application server, API server, metric computation jobs) were hosted on EC2 instances, but each machine was a single point of failure. By putting our services on Kubernetes, we've made our services both scalable and stable. This has been an ongoing project, and we'll be shipping out the final piece this quarter.
Cluster autoscaler: Kubernetes has improved our stability, but we can further automate our cluster management workflow by leveraging autoscaling. We'll be integrating with a cluster autoscaler so that our compute resources can be automatically adjusted for better stability and cost reduction.
Database connection pooler: As we signed larger enterprise customers, traffic to our products significantly increased, requiring more connections to the database. Occasionally, the number of connections would near the limit, posing a stability risk. We've introduced a connection pooler to make sure that connections are efficiently reused, relieving our database cluster of increasing pressure.
Monitoring and observability platforms: Our monitoring and observability platforms have enabled us to deliver reliable, scalable, and performant systems. We shipped distributed tracing just last year, and will continue to invest in this area to give our engineers full insight into our systems.
Development environment: We’ve empowered our engineering team to test their changes quickly with Remote Dev, our remote development environment. We’re anticipating the engineering team to grow significantly this year, so we’re focused on further improving our development environment to unlock larger product wins faster.
Security systems: For many enterprise customers, security is a prerequisite to using any platform, Assembled included. In order to expand our pool of enterprise customers, we must ensure we have the appropriate security measures in place. This quarter, we will be implementing an intrusion detection/prevention system which will monitor, alert, and prevent suspicious network traffic within our systems.
