TensorFlow Developers Hiring Guide

Take a look into the future with TensorFlow

Machine learning has been widely accepted as the future of technology – and with good reason. Artificial intelligence and machine learning are both used by nearly every industry for numerous purposes. Businesses use both AI and ML for training and inference of deep neural networks, to help power nearly every layer of their delivery pipelines.

Machine learning is used in the retail, medical, machine, software, support, and finance industries. In fact, there’s hardly a business sector that ML and AI haven’t touched. What’s more, ML and AI don’t only save you money, but also make your delivery chains and support systems work more efficiently.

Machine learning and artificial intelligence have found their way into technologies such as:

  • Customer recommendation engines
  • Chatbots
  • Decision support
  • Customer churn rate reparation
  • Dynamic pricing
  • Market research
  • Customer segmentation
  • Fraud detection
  • Image recognition
  • Operational efficiency
  • Data abstraction and extraction
  • Sales data input automation
  • Sales call analytics
  • Sales attribution
  • Real-time analytics
  • Intelligent call routing

There’s very little you can’t do with machine learning and artificial intelligence.

But how does a business go about implementing ML and AI? You probably assume this technology is above the ability of your developers and teams. You might be surprised at how accessible it is. One reason this is so is because of TensorFlow.

Google has become the greatest champion of machine learning. The company knew it had the most powerful ML infrastructure in the world and wanted to develop the means to share that platform. For that, the Google developers created an open-source library of tools that enable developers to build deep learning into applications, platforms, and other products. That’s how TensorFlow was born.

    Job Description

First let's discuss what TensorFlow does and what it is, as it can be a bit confusing. Let's use Android phone photography as an example. When you use your phone to take a photo, you might snap an image of a location. When you do, you might discover that Google Photos is capable of identifying a landmark in that image (say the Golden Gate Bridge). How does Google Photos pull that off? Through TensorFlow.

TensorFlow offers a collection of libraries and modules that enable the construction and execution of what is called TensorFlow computations. These computations are expressed in stateful data flow graphs which make it possible for Google Photos to accurately identify landmarks.

Originally, Google developed what was called DistBelief, which worked on a positive reinforcement model. How this worked was simple: A machine was shown an image and was then asked to identify the image. An incorrect guess would lead to an adjustment so it could better recognize the image.

The next phase in that project was TensorFlow, which improved on the concept by employing layers of data, called Nodes. As the machine dove deeper into the layers of nodes, it could be asked (and answer) more and more complex questions about an image. One layer might require the machine to recognize a general shape, such as "round." A deeper layer would then require the machine to recognize a more specific shape, such as an eye. This process (from input through data layers to output) is called a tensor, which is where the name TensorFlow comes from.

Thanks to TensorFlow, devices continue to become smarter and smarter. And with the constant rise and assimilation of Big Data, the need for ML and AI has become critical for big businesses, as data is the driving force behind innovation and market expansion.

Thanks to ML and AI, businesses are now better able to use massive amounts of data to train their software to work more efficiently and effectively.

For your company to make use of TensorFlow, your developers are going to need to know a few languages. Those languages include:

  • Python
  • JavaScript
  • Swift
  • C
  • Go
  • Java
  • Haskell
  • C#

Your engineers don't have to know every one of those languages, but they will certainly need to know Python, as it’s the most commonly used programming language for TensorFlow.

How difficult is it to find good TensorFlow developers?

Although finding developers that can work well with Python and JavaScript is relatively easy, you're going to have to focus your search on developers who also understand how to work with machine learning and artificial intelligence. Without a solid understanding of those 2 concepts, developers will have a hard time working with TensorFlow.

Those engineers will also need to know how to use:

  • TensorFlow Serving - a flexible serving system that makes it possible for developers to seamlessly serve and work their learning models once they're trained.
  • TensorFlow Lite - a deep learning framework for deploying models on mobile, embedded, and IoT devices.

The good news is that ML and AI are incredibly popular these days, and TensorFlow leads the charge, so you shouldn't have any problem finding strong developers who can effectively work with TensorFlow. Hiring them, though, will come with a significant cost, so keep that in mind.


If your business is serious about remaining relevant and being able to keep up with the competition, you're going to have to take  machine learning and artificial intelligence seriously. To do that, you're going to need to find the best TensorFlow developers on the market, so your apps and services can benefit from deep learning.

TensorFlow was developed by Google and has become the framework to use for machine learning. In fact, TensorFlow has become the de facto standard for today’s market. And because TensorFlow is free, and runs on both CPUs and GPUs, it’s even more attractive to more companies looking to leverage machine learning.

But don’t think you can just throw TensorFlow at your current developers and have them start implementing machine learning right away. This tool can be very challenging. Developers will need to have a solid understanding of both Python and C, which are the 2 languages that have stable and official TensorFlow APIs. 

Although this full-blown machine learning research and production tool can be a bit intimidating at first, it’s possible to create simple predictions on data sets. But to get the most out of TensorFlow, you’re going to need experience.

What can you do with TensorFlow? This machine learning framework can be applied to use cases like:

  • Voice and sound recognition
  • Text-based applications for things like threat detection and sentiment analysis.
  • Image recognition
  • Analyzing time-series data
  • Video detection
  • Self-driving vehicles
  • Flaw detection
  • Air, land, and sea drones
  • Mobile image and video processing

PyTorch was created by Facebook AI Research (FAIR) to serve as a leading competitor to TensorFlow. PyTorch immediately took off and has become one of the most popular machine learning frameworks on the market. When deciding on an ML framework, the choice generally comes down to either TensorFlow or PyTorch.

Like TensorFlow, PyTorch can run on both CPUs and GPUs. However, where TensorFlow can make it possible to deploy a new model with incredible speed, PyTorch offers far more customization by following a traditional Object-Oriented Programming approach.

PyTorch also has some of the fastest training times of all machine learning frameworks. Although the speed might seem insignificant on a project-by-project basis when those projects scale to enterprise proportions (such as when using massive data), the speed becomes consequential.

In order for your developers to make use of PyTorch, they’ll need to understand Python. Once up to speed, your developers can use PyTorch for such things as:

  • Implement network architectures like RNN, CNN, LSTM.
  • Building deep learning libraries.
  • Automatic calculation of differentiation.

PyTorch is primarily used for research, which makes it a great fit for businesses needing deep dives into data, which can result in detailed analysis.

Some of the benefits of PyTorch include:

  • Building computational graphs and changing them on the fly.
  • Running ML models in batches, in parallel, or on multi-GPU setups.
  • Integrating it with NumPy testing tools for enhanced unit testing.
  • Transferring computations before GPU and CPU.
  • Shrinking images for increased performance.
  • Easy debugging.
  • Dynamic computational graph support.
  • Cloud support.

For your developers to get the most out of PyTorch, they’ll need to have a solid understanding of Tensors, Python, and NumPy. For more information, check out the PyTorch Get Started guide.

Keras is built on top of TensorFlow and provides a Python interface to make machine learning modeling a bit easier. By simplifying a number of the steps (such as offering all-in-one models), Keras can work with the same code on either CPUs or GPUs. Keras also includes several commonly-used neural-network building blocks, such as:

  • Layers
  • Objectives
  • Activation functions
  • Optimizers

All of this put together makes Keras considerably easier to use for working with both text and images. Of course, Keras isn’t limited to neural networks and can work with convolution, recurrent neural networks, dropout, batch normalization, and pooling. Keras can be used for machine learning models on iOS, Android, the web, or even within a Java Virtual Machine.

Keras was created using 4 guiding principles:

  • Modularity – All concerns of a deep learning module are discrete components and can be combined in arbitrary ways.
  • Minimalism – Keras provides just enough to achieve the stated outcome.
  • Extensibility – New components can be easily added.
  • Python – Everything must be native to Python.

Because Keras is a minimalist Python library (that can run on top of TensorFlow), it’s important that your developers have a deep understanding of Python and TensorFlow, as well as how deep learning research works (and how it can be applied to your business).

To learn more about Keras, make sure to read the official guides.
