Road sensor field data collection — US, own vehicle required

We are an early-stage company developing a road-hazard measurement system. We need a US-based technical contractor to collect real-world driving data: forward-facing road video paired with motion-sensor logs from an Android app we provide, driven over road defects that have documented municipal 311 reports. This is field work combined with light data extraction. It is not remote analysis and it is not software development. The most important qualification is precision. Data quality here depends entirely on consistent setup and repeatable execution — same mount position, same speeds, same route, every session. We are looking for someone with an engineering, QA, field-testing, or research background who understands why that matters and will flag deviations rather than paper over them. REQUIRED: YOUR CITY MUST PUBLISH 311 DATA A core part of this project is cross-referencing our sensor measurements against publicly reported road defects. You must be located in a US city that publishes 311 / service-request / road-defect data as downloadable open data (for example via an open data portal or SeeClickFix). We will ask you to link to it in your application. If your city does not publish this data, this project is unfortunately not a fit. SCOPE OF WORK Milestone 1 — 311 extract and route proposal (desk work, no driving) • Pull your city's open 311 / road-defect reports for the last 24 months • Deliver as a spreadsheet: report ID, date reported, location or coordinates, category or description, status, and date closed where available • Include the source URL and date pulled • From that data, propose a driving route covering 6-10 pothole locations, favoring reports that are still open or recently reported • Do not clean, filter, or interpret the underlying data — deliver it as extracted Milestone 2 — Setup and test session • Install our Android app and mount two phones per a written protocol we provide • Drive the proposed route once, making repeat passes over each target defect at specified speeds • Upload video and session data, plus a written session log Milestone 3 — Full collection (scope and price agreed after Milestone 2) • Additional sessions with repeat passes, per protocol We evaluate at each milestone before proceeding. Milestone 1 is the entry point for everyone. REQUIREMENTS • Located in the United States, in a city with published open 311 / road-defect data • Own vehicle, valid license and insurance • Android phone, Android 10 or newer, available to run our logging app (required — the app is not available on iOS) • Second phone capable of recording 1080p video • Two rigid phone mounts, or willingness to purchase them (reimbursed) • Comfortable with spreadsheets and downloading data from an open data portal • Able to follow a written technical protocol precisely and document any deviation NICE TO HAVE • Engineering, QA, field testing, or research background • Experience with accelerometer, IMU, or other sensor data • Familiarity with your municipality's open data portal or Open311 APIs WHAT WE PROVIDE • The Android logging application • A written field data collection protocol covering mounting, speeds, session procedure, and logging • Reimbursement for phone mounts and mileage • Coverage for any vehicle damage arising from the collection work A note on that last point, since we would rather be upfront: this work involves deliberately driving over road defects at moderate speeds. We consider damage unlikely at the speeds specified, but if anything happens to your vehicle during a session, we cover it. A short mutual NDA is signed before we share the application and protocol. Milestone 1 requires no confidential material from us. BUDGET Fixed price per milestone. Milestone 1 is posted at $75. Milestones 2 and 3 are agreed separately based on scope and are substantially larger. When you apply, please answer the three screening questions directly. Proposals that skip them will not be reviewed.
