Quick Summary

Support Engineer (CST) is responsible for ensuring the smooth operation of the enterprise-grade AppStore, providing top-notch customer support and ensuring seamless app access for our users.

Job Description

Imagine having an enterprise-grade AppStore at work — one that ensures you can easily search, request, and gain access to any app you need, precisely when you need it. No more long waiting times with outstanding IT requests. Lumos is solving the app and access management challenges for organizations of all sizes through a unified platform. Our fast-growing startup is pioneering the way to untangle the complex web of app and access management by building the critical infrastructure that defines relationships between app, identities and data.

Why Lumos?

• Jump on a Rocketship: Since launching out of stealth mode just over 2 years ago, our team has grown from 20 to ~100 people and our customer base has 10x’ed with companies like GitHub, MongoDB and Major League Baseball!

• Build with Renowned Investor Backing: Andreessen Horowitz (a16z) backed us since the beginning and we've raised over $65m from Scale, Neo, Greg Brockman (President at OpenAI), Phil Venables (CISO at Google), and others.

• Thrive in a Unique Culture: You’ll join an early-stage company where you have actual influence on the trajectory of the company. We deeply care about our people and the philosophy we live by - check out our values here.

As a Support Engineer (PST) at Lumos, you have the opportunity to be one of the first 5 folks building out our support organization. Partnering with the Solutions Engineering team as well as Customer Success Managers, our goal is to find the equilibrium between quantity and quality, where speed and accuracy are our best offense and defense. As Lumos grows its client base by more than double this upcoming year, your role is essential to the success of our customers. Enablement, troubleshooting, and clarity of communication are pillars in your everyday interactions. In the Support Engineer role, you’ll not only report into the Support Engineering Lead, but you’ll partner with them in developing clear processes for Support at Lumos and truly shape the future of the team.

✨ Your Responsibilities

• Creating a World-Class Support Experience: Interacting with our client base on the day to day, you will have a direct impact on shaping their experience with Lumos. We want to ensure attention to detail, a friendly approach, and consistent care are present in each and every interaction.

• Troubleshooting Complex Technical Errors: Lumos rolls out new product features often. With this level of innovation can also introduce unexpected behaviors. It’s essential that you stay on top of the product development, relay customer feedback through validating enablement materials, and are extremely clear in your handoffs to our engineers for further actioning as needed.

• Proactively Developing Product Expertise: Similar to the above, partnering with our Product Managers is essential. If we don’t have the information we need to successfully support customers on a new feature rollout, seek to discover. By establishing these mutually beneficial relationships, you’ll become a product expert and the voice of the client in product development.

• Reflecting On and Finding Solutions for Current Support Opportunities: Because we’re building this team from the ground up, your thoughts, opinions, and considerations are essential to our longterm success. Giving feedback and being creative in your problem solving are critical.

🙌 What We Value

We purposefully did not create a standard list of minimum qualifications because we care much more about your motivation, excitement, and potential to grow into the role than about your CV.

Instead of focusing on what people need to have, we focus on what people need to do. Additionally, we try to find out whether you would be a good fit for Lumos based on our values that define how we achieve outcomes and what characteristics we value.

*We encourage you to apply even if you think you might not be perfect fit! 🤝

• $85,000 - $115,000. Note that this range is a good faith estimate of likely pay for this role; upon hire, the pay may differ due to skill and/or level of experience.
