Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

Behavioral

Tell me about a time you built a tool or script that other engineers ended up relying on. What did it do and what happened when it broke?

whether their Python experience is production-grade automation versus disposable scripts

Tell me about the worst production outage you were on point for. What was the actual root cause and what changed afterward so it couldn't happen again.

ownership of postmortems and whether fixes were structural or just patches

Tell me about a time you had to push back on a deadline set by a vendor or field crew in a different time zone, where the schedule didn't match reality.

how they handle coordinating external parties under pressure without losing the timeline entirely

This job means real travel to towers, rooftops, and rural sites, sometimes on short notice, plus a follow-the-sun on-call rotation. What's your experience with that kind of schedule, and how do you think about the trade-offs?

honest self-assessment of whether the lifestyle demands of the role are sustainable for this person

Technical

Walk me through a wireless link you designed from scratch, from the link budget and Fresnel zone clearance to the antenna and mount geometry you chose.

whether the candidate has actually done RF path design end to end or just knows the vocabulary

How would you design a telemetry pipeline that collects RSSI, SNR, and BER from a mix of vendor radios and turns that into useful alerting instead of noise?

systems thinking around monitoring at scale and judgment about alert fatigue

Have you worked with FCC ULS or ASR data, or done frequency coordination for licensed microwave links? Walk me through how you'd research a new path before filing.

direct exposure to the specific regulatory datasets this job depends on, not just general RF knowledge

We're moving radio and link configuration into git so changes are reviewed and versioned. How would you structure that so a bad change gets caught before it hits a live path?

understanding of change control discipline in a low-tolerance production environment

Where do you see LLM or AI-assisted tooling actually being useful in network operations, and where do you think it would just get in the way?

realistic judgment about applying newer tooling versus chasing a buzzword

Explain DWDM channel planning and how it fits into a wireless network's overall path, as if you were teaching it to a new hire.

depth on the wireline half of the job, since candidates often only prepare for the RF side

Situational

Say you've got a microwave link that's showing degraded SNR and rising BER but RSSI looks normal. How do you go about isolating the fault before you send anyone to the tower?

structured fault isolation skill and whether they know which telemetry actually points to which failure mode

A link you manage is down at 2am and the only person who can get to the tower is a subcontractor you've never worked with before. How do you get them to fix it correctly without you being on site?

ability to write and communicate field instructions clearly enough for someone else to execute reliably

If you found out a competitor's path between two data centers was faster than ours, how would you go about figuring out where the microseconds are being lost and whether it's worth chasing?

whether they think about latency as a measurable, defensible research problem, not just an engineering task

Tell me about a maintenance window you planned on a live, latency-sensitive network. What could have gone wrong and how did you protect against it?

rigor around change planning and outage notification when real money is on the line

Our culture is unique. Constant innovation requires fearlessness, creativity, intellectual honesty, and a relentless competitive streak. We believe in winning together and unlocking unique individual talent by incenting collaboration and mutual respect. At Jump, research outcomes drive more than superior risk adjusted returns. We design, develop, and deploy technologies that change our world, fund start-ups across industries, and partner with leading global research organizations and universities to solve problems. Tower Pros is the dedicated field operations support team for some of the most successful HFTs in the world. It is our responsibility to build and maintain first-in-class wireless networks that compete in the fast-paced, ever-evolving landscape of financial markets. This is a team for individuals that are truly interested in having their skillsets consistently challenged and actively want to learn new skills as the needs of the business grow. We are focused on a team environment, and the most successful applicants will work as part of a team to constantly deliver and improve on the work produced. This role sits at the intersection of software, RF engineering, and network operations. Underneath all of it is one standard: our paths should be the fastest in the market and stay that way. moving target, so this job is as much about finding the next microsecond as defending the ones we already have.   What You'll Do: <ul class="ak-ul" data-local-id="f11fd3631416" data-prosemirror-content-type="node" data-prosemirror-node-name="bulletList" data-prosemirror-node-block="true"> <li
