Network Engineer

Jump Trading Group is committed to world class research. We empower exceptional talents in Mathematics, Physics, and Computer Science to seek scientific boundaries, push through them, and apply cutting edge research to global financial markets. 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:

• Build and run the monitoring and mapping platforms that give the team a live view of the network, including the telemetry pipelines that collect and baseline link performance (RSSI, SNR, BER), the alerting that fires off them, and the interfaces engineers actually work in.

• Write device control and protocol integrations for amplifiers, radios, controllers, and power systems over serial/TCP, SNMP, and vendor APIs.

• Develop AI and LLM-assisted diagnostic and chat-ops tooling that shortens incident triage and on-call response.

• Manage radio and link configuration as code in git, so that changes to the network are reviewed, versioned, and repeatable.

• Build the measurement and analysis tooling that benchmarks our paths against what the market is achieving, identifies where we lead and where we have slipped, and turns the gap into a recommendation worth building.

• Work public regulatory, spectrum, and structure datasets (FCC ULS, ASR, prior coordination filings, and international equivalents) as research inputs, and translate what they show into route and site strategy.

• Design and evaluate wireless paths: line of sight and Fresnel clearance, link budgets, and antenna and mount geometry.

• Run frequency studies and prior coordination for new and modified licensed links.

• Engineer the wireline side of wireless: DWDM channel planning, dark fiber turn-ups, exchange cross connects, and precision timing.

• Commission new links across licensed microwave, millimeter wave, free space optics, and shortwave, verifying post-cutover performance against expected receive levels.

• Lead incident response on production paths: triage, fault isolation, signal spectrum analysis, and historical performance review, culminating in a documented fault hypothesis and parts list for field repair.

• Drive every incident through resolution and postmortem, and feed what broke back into the monitoring, tooling, and network design so it can't break the same way twice.

• Plan and execute changes on live networks, including maintenance window planning and formal outage notification to external counterparties.

• Write the runbooks and field work instructions that let remote crews and on-call engineers execute reliably without you on the line.

• Identify and develop new sites: towers, rooftops, water tanks, data centers, and greenfield land.

Skills You'll Need:

• Degree in Electrical or Computer Engineering, Computer Science, Information Systems, or a related technical field, or equivalent practical experience in RF,
