Joining Foundry

As a key member of our team, you’ll spearhead the development, deployment, and maintenance of critical new services, ensuring they meet our high standards of stability and reliability.

You’ll apply cutting-edge techniques rooted in broad industry experience to enhance our platform’s performance. Your responsibilities will span both Cloud SRE and on-premise systems administration, with a focus on managing the stability of advanced GPU services and optimizing monitoring, alerting, and incident response frameworks, guided by Service Level Indicators (SLIs) and Objectives (SLOs).

Collaboration is at the heart of this role—you’ll work closely with diverse product teams and technical customers to design scalable solutions. Using Infrastructure as Code (IaC) principles, you’ll implement fault-tolerant design patterns and build automation tools to streamline operations. Participation in an on-call rotation will be essential to maintain service reliability.

Salary Range Information 

In consideration of market analysis and various pertinent factors, the remuneration bracket for this role is set between $170,000 and $230,000. Nevertheless, adjustments beyond this range could be warranted for candidates whose qualifications substantially deviate from those delineated in the job description.

In-Office requirement

At Foundry, we take our work extremely seriously, though not always ourselves. We recognize that we are striving to achieve something substantial—an all-too-rare and elusive counterfactual contribution. Our work is not easy, so we seek out any lever that can accelerate our progress and increase the likelihood of realizing our full ambitions. Working collaboratively in person is one such lever.

Our headquarters is in Palo Alto (next to Caltrain on University Ave.), and we recently opened a new office in San Francisco (Financial District/SoMa) for our teammates based there. We expect team members to primarily work from their local office (Palo Alto or San Francisco), with everyone gathering at HQ one day a week while our team remains small and cross-team collaboration is critical.

This approach is built on trust. We take our mission seriously and are committed to fostering an environment where you can make impactful decisions and drive success. We also understand that life can present challenges, and if extenuating circumstances arise, we’re here to support you.

Ultimately, we believe this guidance helps us be as effective as possible while maintaining the spirit of teamwork and flexibility.
