Operations Manufacturing Test Lead

JOIN THE TEAM BRINGING ADVANCED AUTONOMY TO THE BUILT WORLD

At Bedrock, we’re moving AI out of the lab and into the real world. Our team is composed of industry veterans who helped launch Waymo, scaled Segment to a $3.2B acquisition, and grew Uber Freight to $5B in revenue. Today, we’re deploying autonomous systems on heavy construction machinery across the country, accelerating project schedules of billion-dollar infrastructure projects and improving safety on job sites. Backed by $350M in funding, we’re working quickly to close the gap between America's surging demand for housing, data centers, manufacturing hubs, and the construction industry's growing labor shortage.

This is where algorithms meet steel-toed boots. You’ll collaborate with construction veterans and world-class engineers to solve physical-world problems that simulations can’t touch. If you're ready to apply cutting-edge technology to solve meaningful problems alongside a talented team—we'd love to have you join us.

DAY IN THE LIFE - MANUFACTURING TEST ENGINEER

MORNING: DATA REVIEW & PRODUCTION PULSE CHECK

You start by checking what happened overnight or on the previous shift:

• First Pass Yield (FPY) by station

• Top failure modes and pareto trends

• Test station uptime and bottlenecks

• Any line stops or escalations

If a failure spikes—say a communication test or sensor calibration—you flag it immediately.

Then you join a quick stand-up with manufacturing, quality, and engineering:

• What’s breaking on the line right now?

• Are failures real (product) or false (test issues)?

• What needs immediate containment vs. deeper investigation?

You leave with a clear priority: keep the line running, but don’t let bad units escape.

MID-MORNING: ON-THE-LINE DEBUGGING

You’re on the manufacturing floor (or remote into stations), working side-by-side with technicians.

Typical scenarios:

• A unit is failing functional test intermittently → you hook into logs, probe signals, and check if it’s hardware, firmware, or test script timing

• A station is slowing throughput → you optimize sequence timing or parallelize steps

• A new build variant isn’t flowing correctly → you adjust work order/test routing in MES

You’re constantly asking:

• Is this a real defect or a test artifact?

• If it’s real, is it design, component, or process-related?

• How do we contain it now and detect it earlier next time?

MIDDAY: TEST DEVELOPMENT & ITERATION

Back at your desk or lab bench, you shift into build mode.

You might be:

• Writing Python scripts to automate a new functional test

• Adding diagnostics to isolate failures faster (better logging, error codes, signal capture)

• Integrating new hardware into the test system (DAQs, sensors, fixtures)

• Expanding test coverage to catch a recently discovered issue

This is where you improve the system so the same issue doesn’t keep showing up on the line.

EARLY AFTERNOON: BRING-UP & NEW PRODUCT SUPPORT

If you’re in EVT/DVT/PVT or launching a new product, this block is intense.

You’re:

• Bringing up new test stations for a prototype or pilot build

• Debugging early design issues exposed during testing

• Defining pass/fail limits where none existed before

• Rapidly iterating test sequences as the product evolves

Expect ambiguity—things aren’t fully defined yet, and you’re helping shape both the test strategy and the product quality bar.

MID-AFTERNOON: FAILURE ANALYSIS & CROSS-FUNCTIONAL WORK

You sit down with hardware, firmware, and quality engineers to go deeper on key issues:

• Reviewing failure logs and waveform captures

• Reproducing issues in the lab

• Running experiments to isolate root cause

You help answer:

• Did test catch this early enough?

• Should this be moved upstream (design validation vs. production test)?

• What additional coverage is needed to prevent escapes?

This is where you connect test → design → manufacturing → field performance.

LATE AFTERNOON: SYSTEMS, SCALING & OPTIMIZATION

Now you zoom out and improve the broader system:

• Updating MES flows (test steps, routing, traceability)

• Refining test limits to reduce false failures without letting defects pass

• Improving test time to increase throughput

• Building dashboards for test data visibility

You may also work on:

• Reliability testing setups (burn-in, stress tests)

• Automation to reduce manual intervention

• Smarter failure classification (rule-based or AI-assisted)

END OF DAY: WRAP-UP & PRIORITIZATION

Before signing off, you:

• Check if critical line issues are contained

• Ensure test changes are deployed and documented

• Align with the next shift or offshore teams

• Set priorities for the next day (new tests, top failures, line risks)

WHAT MAKES THE ROLE UNIQUE

• You are the gatekeeper between manufacturing and the field

• You constantly balance coverage vs. speed vs. cost

• You touch everything: hardware, software, fixtures, data systems, and operations

• Your work directly impacts yield, reliability, and customer experience

IN ONE SENTENCE

You spend your day building and refining the systems that catch problems early, diagnose them quickly, and keep production moving without compromising quality.

Our roles are often flexible. If you don't fit all the criteria, or are in another location (especially one where we have an office like SF or NY) please apply anyway! We'd love to consider you.
