Lead Edge Engineer

About Us

Queue builds robots to fill prescriptions. Our machine is designed to take stock bottles of medication and produce counted labeled vials so that pharmacists and technicians can spend their time on patients. Our first product is built to work behind the pharmacy counter and to be operated by pharmacy staff.

About the Role

We are building out the Edge squad: the engineers who write the software that runs on our machine and tells its hardware what to do. You are a hands-on technical lead. You own the edge software end to end from design and code to release and behavior in the field and you raise the bar for everyone who builds it. You build to one rule and hold the squad to it: when the machine cannot confirm a step it stops safely and says why.

This is a lead-level role: a staff engineers technical bar plus delivery through a team. It is hands-on and it is not a people-management role.

What Youll Own

• Design and code The design of the edge software and the code that carries it from the links to the boards to the state machines that sequence each fill. You stay in the code and review the squads.

• Contracts at the boundaries The contracts with the microcontrollers and the vision service. You design and version them so that old and new versions work together through a release.

• Releases and field behavior How a release of the edge software is built tested and shipped what the software reports from the field and how it is diagnosed from a distance. You work on updates with the platform and systems reliability engineers and on the image with the engineers who own it.

• The seams Where the edge software meets firmware vision the cloud and the image. A fault that falls between two squads is yours until it is fixed and you fix it with the squad on the other side.

• The squads bar What you accept in review becomes the standard so you define it crisply hold it every time and measure quality against it. You grow the engineers around you into leaders: you pair and coach give them the lead and back them and you interview the ones who join.

• Decisions in writing You write decisions down with the options you weighed and why and share them early for challenge across the squads so engineers can make the next decision without you.

• Fail-closed behavior The rule on every path the squad owns: when the machine cannot confirm a step it stops safely and says why. You design the failure path first and the squad does too.

What stays with others so that you know where your work stops: the operating-system image stays with the engineers who own it the cloud with the platform engineers and the call that a release is ready with software leadership.

First 90 Days

• Day 30: You have built the edge software run it on a bench and merged changes through review. With the firmware vision and platform engineers you have traced a fill across every seam and you can name each point where it has to stop if a step cannot be confirmed.

• Day 60: You own one seam end to end with the squad on the other side: its code its contract and what the edge software does when the other side fails. You have planned the squads next release with its engineers each change with an owner and written down the bar you hold in review.

• Day 90: You have scoped and reviewed a change that an engineer on the squad has taken through release to machines on the bench with its failure paths tested first. You have written down the reasons behind one design decision so that engineers can act on it without you and the squad reviews to what you wrote down.

What Were Looking For

Must-Have

• Ownership you have written production C C or Rust on Linux and owned a devices software end to end from the first design to the fault found in the field including faults that started in another teams part of the system.

• Hardware integration over buses CAN RS-485 and other serial links USB. You debug at the wire when the logs and the hardware disagree.

• Real-time orchestration and state machines you have designed the sequencing of motion sensing and I/O where partial failure is normal and you design the failure path first: when a step cannot be confirmed the system stops safely and says why.

• MCU boundary literacy you understand how a microcontroller runs and what it exposes to a Linux host and you have designed versioned device protocols with firmware that held up through change for example a protobuf schema a CAN message set or a register map.

• Embedded Linux integration you have done substantial work getting software running well on an embedded Linux system: its services devices start-up configuration and updates worked out with the owners of its image.

• Connected device fleets you have run devices in the field: updates remote diagnostics telemetry and the recovery of a unit you cannot touch.

• Hardened device platforms you have shipped software on devices with verified start-up signed updates and a read-only system and you design software that works within them.

• Technical leadership you have made a teams engineering better through design review and mentoring without needing a title. You ask for challenge on your own designs change course when the evidence says so and say early with data when a commitment will slip. When several things go wrong at once you put them in order and finish one before you start the next.

The edge software is written in Rust and you will work in it every day. Rust in production is strongly preferred.

Nice-to-Have

• Industrial x86 and ARM platforms in a shipped product.

• Full ownership of an embedded Linux distribution: building and maintaining the image of a shipped device from what goes into it to how it updates.

• Kernel and board bring-up: drivers device trees and boot on a new board.

• NVIDIA Jetson: JetPack and Linux for Tegra secure boot field updates and the inference stack.

• Robotics medical devices automotive or industrial automation.

How We Hire

• Recruiter Screen (30 min)

• Technical Interview (90 min) a take-home exercise of 2 to 3 hours in C C or Rust sent at least 24 hours before: a small piece of device software built around a state machine which has to stay correct when power is lost at any step. We go through it together then build on it.

• Design Interview (60 min) the path a new version of the software takes to a fleet of machines with the failure cases in from the start and where the edge softwares decisions stop and another squads begin.

• Leadership Interview (60 min) how you lead through a team.

Two interviewers score each technical stage independently.

What We Offer

• Ownership the edge software end to end from design to the field

• Hard problems: real-time sequencing across boards the seams with firmware vision and the cloud and machines in the field you cannot touch

• Small team zero bureaucracy high trust
