Senior C/C++ Engineer (OpenCV + macOS Packaging) Build & Package up for Computer Vision Demo - Contract to Hire

Job Overview

We are looking for a senior C/C++ engineer to take an already-specified computer vision demo codebase and compile, integrate, and package it into a working macOS application (.app) for internal demo use.

This is not a research role and not a greenfield build.

The system architecture, kernel, CLI wrapper, and packaging blueprint are already defined. Your job is to:

• finalize build integration

• validate runtime behavior

• bundle dependencies

• produce a stable Apple Silicon .app demo package

The work is highly specified and should be completed quickly and precisely by the right engineer.

What You Will Be Working On:

You will be working on a deterministic computer vision demo system that:

• runs a fixed-point C kernel (no floating point math)

• processes raw video frames (.yuv)

• renders a 3-pane OpenCV visualizer

• streams live NDJSON telemetry to a terminal

• is packaged into a macOS .app for presentation to hardware partners

The core executable (cosimo_demo) already exists in specification form. Your task is to make it build, run, and package cleanly.

Scope of Work:

1. Build & Integration:

• Wire and validate CMake build:

• root CMakeLists.txt

• core/ (C deterministic kernel)

• cli/ (C++ wrapper)

• Ensure successful build on Apple Silicon (arm64)

2. Runtime Validation:

• Verify cosimo_demo runs correctly:

• frame ingestion from .yuv

• kernel execution (cosimo_compute_d0)

• 3-pane OpenCV visualizer

• quiver (vector) overlay rendering

• Validate CLI modes:

• standard run

• --headless

• telemetry rate control

3. Telemetry & I/O:

• Ensure strict telemetry contract:

• NDJSON output to stdout

• fflush(stdout) after each line

• no mixing of logs into stdout

• all diagnostics → stderr

• Validate latency measurement:

• must reflect kernel execution only

4. Fixture Validation:

• Confirm all demo fixtures:

• are 1920x1080

• luma8

• valid .yuv streams

• Ensure system fails cleanly on malformed input

5. macOS Packaging (.app):

• Execute packaging script:

• bundle executable into .app

• include fixtures

• bundle OpenCV dependencies (dylibbundler)

• Validate:

• Finder launch

• AppleScript launcher behavior

• fixture selection prompt

• terminal telemetry window

• visualizer window

6. Final Validation:

• Run full demo locally:

• verify all fixture modes

• confirm no crashes

• confirm telemetry + visuals behave correctly

• Deliver:

• working .app

• zipped distribution package

• brief build/run notes

What You Are NOT Doing:

• No ML model development

• No new algorithm design

• No architecture redesign

• No blockchain / backend work

• No UI/UX redesign

This is a precision execution and packaging task, not an exploratory project.

Required Skills:

• Strong C/C++ (5+ years)

• OpenCV (desktop apps)

• CMake build systems

• macOS development (especially Apple Silicon)

• Dynamic library handling (.dylib, install_name_tool, dylibbundler)

• CLI applications and debugging

• File I/O (binary / raw frame data)

Strongly Preferred:

• Experience packaging macOS .app bundles

• Experience with ARM64 environments

• Experience shipping internal tools or demos

• Experience debugging native runtime issues

Nice to Have:

• SIMD / low-level performance awareness

• Experience with video pipelines or frame processing

• Familiarity with deterministic or fixed-point systems

Project Timeline:

• Expected duration: 1 or 2 days, depending on how experienced and efficient you are.

• If you do a good job, we have more work for you. This is a discrete assignment to determine how efficient and effective you can be with instructions and objectives.

This assumes:

• codebase is already defined (it is)

• work is integration + packaging (not new development)

Deliverables:

• Fully working Apple Silicon .app

• Verified execution across all demo fixtures

• Clean telemetry output

• No runtime dependency issues

• Short documentation (build + run instructions)

How to Apply:

Please include:

1. Relevant examples of:

• C/C++ + OpenCV work

• macOS packaging or native apps

2. Confirmation you’ve worked with:

• CMake

• macOS .app packaging

3. Estimated time to complete (in hours)

Final Note

We are looking for someone who can:

take a well-defined system and execute it cleanly, quickly, and without introducing ambiguity

If you tend to over-engineer or redesign things unnecessarily, this is not the right fit.

If you are precise, fast, and experienced in native systems and packaging, this should be a straightforward and rewarding project.

ADDITIONAL CONFIDENTIAL SOFTWARE INSTRUCTIONS WILL BE GIVEN UPON HIRING.
