We champion freedom of speech and strive to create a platform that embraces diverse perspectives. Our commitment is to foster open dialogue and empower individuals to express themselves freely.

We value:

• Writing code rather than documents
• Shipping products rather than talking about roadmaps
• Big features rather than changing button colors

If this sounds like you, let’s talk.

**Your Role:

As a Machine Learning Engineer, you will play a pivotal role in providing the most compelling experience on X. Your responsibilities will include:

• Designing and architecting recommendation algorithms across various product surfaces in X
• Collaborating with cross-functional teams to integrate machine learning models into our platform
• Iterating and improving the algorithm by gathering user feedback in real time through experimentation
• Ensuring scalability and efficiency of machine learning systems
• Mentoring junior engineers and contributing to the team's growth
• Staying updated on Machine Learning and Deep Learning industry trends

**Who You Are:

We're looking for exceptional engineers who are passionate about our mission and have a strong desire to make a meaningful impact. The ideal candidate will have:

• Master, Post-graduate or PhD in computer science, machine learning, information retrieval, recommendation systems, natural language processing, statistics, math, engineering, operations research, or other quantitative discipline; or equivalent work experience
• 2+ years of industry experience working with recommender systems and/or deep learning applications (note - we are open to hiring for this role at all levels)
• Good theoretical grounding in core machine learning concepts and techniques
• Ability to perform comprehensive literature reviews and provide critical feedback on state-of-the-art solutions and how they may fit to different operating constraints
• Experience with a number of ML techniques and frameworks, e.g. data discretization, normalization, sampling, linear regression, decision trees, SVMs, deep neural networks, bandits, reinforcement learning, etc.
• Familiarity with one or more DL software frameworks such as Tensorflow, PyTorch.

At X, our small but fast-paced team values innovation, creativity, and a strong commitment to our mission. As a Machine Learning Engineer, you'll have the opportunity to make a significant impact on the future of X and our aspiration to build the Everything App.

If you're an exceptional engineer who shares our passion for freedom of speech, we'd love to hear from you.
