We're disrupting the $16 billion music marketing industry and need a senior full-stack developer to help update our entire platform. This isn't just a contract gig - it's a potential pathway to a full-time, high-impact role at an investor-backed startup.

What Makes This Different:
You'll work directly with the founders (myself + 2 growth-focused co-founders) to architect and build something that actually matters. No layers of management, no corporate bureaucracy - just focused development on a platform that's already gaining serious traction.

The Challenge:
We're updating our platform in 4-6 weeks (targeting early September). It's ambitious, but we have clear requirements, solid architecture decisions, and founders who understand what it takes to ship quality code fast.

What We Need:
- 4+ years of production experience with modern web stacks
- Strong TypeScript skills (this is our primary language)
- Proven experience with tRPC and Next.js
- Turborepo and Yarn workflow experience
- ORM experience (we use Drizzle, but similar experience works)
- Available to start immediately and commit fully to this timeline

What We Offer:
- $35-55/hour based on experience (paid weekly)
- Performance bonuses for hitting milestones
- Direct equity conversations for the right long-term fit
- Daily collaboration with founders who respect great code
- Real ownership over technical decisions

Our Approach:
Quality over speed, always. We'd rather launch something solid in 6 weeks than something broken in 4. You'll have input on architecture, tooling, and approach - we want a true technical partner, not someone just executing specs.

Ready to build something that changes how artists connect with their fans?

Expert GCP/Cloud Run Developer for WhisperX Diarization Microservice

Job Description:

Project Overview:
We are looking to enhance our existing audio processing pipeline by adding advanced transcription refinement and speaker diarization. We currently have a microservice that handles initial audio transcription, and we now require a second, dedicated microservice to improve accuracy and identify different speakers.

The core of this project is to build and deploy a new, high-performance microservice on Google Cloud Run that leverages the WhisperX library. We are seeking an experienced developer who is not only proficient in the required technologies but can also architect a secure, fast, and cost-efficient solution.

Current Architecture:

Microservice 1 (Existing): An operational service that performs a first-pass transcription on audio files.

Microservice 2 (To Be Built): This is the focus of this project. It will receive data from the first service and perform advanced processing.

Your Responsibilities:

Architect & Design: Propose and implement an optimal and secure architecture for the new microservice. This includes defining the best method for communication and data transfer between our existing service and this new one (e.g., using Google Cloud Pub/Sub, Cloud Storage triggers, or direct HTTP/gRPC requests).

Development: Build the Python application that integrates the WhisperX library to perform:

Highly accurate, word-level timestamped transcription.

Speaker diarization to identify and label different speakers in the audio.

Containerization & Deployment: Containerize the application using Docker and deploy it on Google Cloud Run. The service must be scalable and handle requests efficiently.

Optimization: Ensure the microservice is optimized for both speed (low latency) and cost (efficient use of CPU/Memory/GPU resources). This includes model loading strategies and resource allocation.

Security: Implement robust security best practices for the Cloud Run service, its API endpoints, and any associated IAM permissions or service accounts.

Required Skills & Experience:

Google Cloud Platform (GCP): Proven, hands-on experience with Google Cloud Run is essential. Familiarity with other GCP services like Cloud Storage, IAM, and Pub/Sub is highly desirable.

Python: Expert-level Python programming skills, including experience with web frameworks like FastAPI or Flask.

WhisperX: Demonstrable experience working with the WhisperX library and its dependencies (e.g., torch, torchaudio). You should be comfortable with its diarization and alignment models.

Docker: Strong proficiency in creating optimized and secure Docker containers.

Microservice Architecture: Solid understanding of microservice principles, including inter-service communication, scalability, and stateless design.

API Security: Knowledge of best practices for securing public-facing APIs (e.g., authentication, authorization, rate limiting).

Bonus Points (Highly Valued):

Experience configuring Cloud Run services with GPU acceleration.

Prior work on audio/video processing or machine learning model deployment pipelines.

A portfolio or examples of similar projects.

What We Are Looking For:

We value your expertise and are looking for a developer who can take ownership of this project. You will have the freedom to recommend and implement the best technical solutions to meet our goals. We are looking for a proactive problem-solver who communicates clearly about architectural decisions, progress, and potential challenges.

How to Apply:

Please begin your proposal with the phrase "WhisperX Cloud Run" so we know you've read the entire post.

In your proposal, please include:

A brief description of your experience with similar projects, specifically mentioning your work with GCP, WhisperX, and/or other audio processing pipelines.

Your initial thoughts on the best approach for passing data from our first microservice to this new one, and a brief explanation of why you'd choose that method.

We look forward to collaborating with you!

The bot is to ideally work on ctrader with the bot written in ctraders built in platform cbot. Potential returns after optimisation to aim for 7-11% ROI YoY. Running times will be established after optimisation due to manual back testing playing a large part in the success of the bot.

The idea of the bot is that it is actively monitors the prices points of some of the most popular technical analysis (TA) tools and indicators.
Each TA and indicator is assigned as being either major or minor. Each one is considered a confluence.

The bot will actively monitor for when the different major and minor confluences become within a set price range of each other. The alignment in price of multiple confluences at once is what creates a trade signal.

The bot should draw technical analysis precisely to specific parameters to avoid false readings

Ideally the bot will have the capability of being “customisable” possibly through a user interface. This aspect should allow for the bot to only search for specific major and minor confluences that are selected. This will allow for intensive back testing.

Parameters for position sizing, stop loss levels and take profit levels should be fixed but customisable. Trades should exit upon a trade signal for a counter position.
