How to write a Heroku developer job description


Hiring a skilled Heroku developer means you can deploy and manage apps that perform seamlessly in the cloud. Meanwhile, hiring a Heroku developer with a poor understanding of Heroku's platform and best practices can lead to suboptimal application performance. The developer may write inefficient code, resulting in increased server costs and slow response times. They might also introduce security vulnerabilities.

Crafting a great job description can help you attract top applicants. However, pinpointing the unique blend of technical skills and knowledge to include in your job description can be challenging. 

We can help! Our article guides you through creating a job description that draws in the best candidates, ensuring your team benefits from the full power of Heroku's platform.

What is a Heroku developer?

A Heroku developer specializes in building, deploying, and scaling applications on the Heroku cloud platform. They leverage their coding skills, typically in languages like Ruby or Python, to craft apps that run efficiently on Heroku's Platform as a Service (PaaS) environment.

These developers understand the nuances of cloud architecture and are great at using Heroku's features to optimize app performance, manage workflow, and ensure continuous deployment with minimal downtime. 

Key skills to look for in a Heroku developer

Finding the right Heroku developer for your company means looking for a unique mix of technical prowess and problem-solving abilities.

Hard skills

  • Proficiency in Heroku CLI: A strong candidate must be comfortable using Heroku command-line interface (CLI) for creating, managing, and scaling applications.

  • Experience with buildpacks: The developer should know how to use or create buildpacks (scripts for compiling apps on Heroku).

  • Database management: Experience with PostgreSQL, Heroku's preferred database, is crucial for managing and scaling databases within applications.

  • App optimization: The candidate should demonstrate expertise in dyno management and an understanding of Heroku's metrics for optimizing app performance.

  • Continuous deployment: Familiarity with deployment workflows using Heroku's CI/CD (continuous integration/continuous deployment) tools is essential.

  • Integrations and add-ons: A Heroku developer should have experience integrating third-party services using Heroku add-ons and the Heroku Elements Marketplace.

Soft skills

  • Problem-solving: The ability to quickly identify and resolve deployment issues or downtime is critical.

  • Adaptability: As Heroku evolves, developers must stay current with new features and adapt to them.

  • Communication: Developers should be able to clearly communicate technical details to team members and non-technical stakeholders.

  • Collaboration: Heroku projects often involve working with other developers and IT professionals, so developers must have strong teamwork skills.

  • Proactivity: Developers who seek ways to improve application performance or reduce costs without prompting show a valuable level of initiative.

  • Time management: Prioritizing tasks and managing deployment schedules is key, especially when multiple apps are in development.

How to write an effective Heroku developer job description

Follow these best practices to write a solid Heroku developer job description.

Specify Heroku-related responsibilities

Describing what the job entails using specific details weeds out unqualified applicants while setting clear expectations. 

For instance, stating that the candidate will "manage our Heroku pipelines, ensuring seamless development to production transitions" shows them that precision and expertise in pipeline management are critical to your operations. 

This clarity helps attract professionals who are up for the challenge and possess the right skill set, ultimately saving you time and resources in the hiring process.

Detail technical requirements

When you're specific about technical skills, such as expertise in Heroku Postgres optimizations or familiarity with Heroku Redis, you're essentially filtering for excellence. By listing these precise skills, you encourage applicants who can confidently navigate the complexities of Heroku's platform. 

This specificity brings forward candidates who can hit the ground running while setting a benchmark for the technical competencies required for the role. It ensures that the person you hire will contribute to the technological robustness of your project from the get-go.

Highlight the need for Heroku-specific knowledge 

By underscoring the value of specific knowledge of Heroku – such as knowledge of scaling web applications – you're targeting candidates with the expertise you need. This attracts candidates with experience with the platform who have faced and overcome real-world challenges similar to what they might encounter in your projects. 

"Candidates should have a proven track record of scaling large-scale web applications on Heroku," suggests that you're looking for someone who can ensure scalability and reliability, for example.

Describe the ideal candidate's profile

Painting a vivid image of the perfect Heroku developer gives prospective candidates a glimpse into the future. By illustrating how their expertise will enhance app performance or cut server costs, you appeal to their desire to make a significant impact. 

Language like "the ideal candidate will leverage Heroku to enhance our app's performance, ensuring a robust, user-friendly experience" sets a high standard and shows applicants how their expertise will contribute to your company.

Company introduction

In this section, introduce your company, emphasizing its commitment to innovation and excellence in cloud-based application development.

Benefits of working with [your company]

Detail the specific benefits that a Heroku developer would enjoy at your company. Beyond standard benefits, include opportunities for professional development, like Heroku certification reimbursement or dedicated time for learning new cloud technologies. Mention the availability of powerful workstations, access to premium Heroku add-ons, or the chance to work on cutting-edge projects.

Francis Lacoste, Senior Director at Salesforce Heroku, has stated, "Around 70% of Heroku engineers are working from home, and that ratio is probably going to continue for the foreseeable future." So, if your company has a strong remote work policy, including that in your job description is a good idea.

4 things to avoid when writing a job description for a Heroku developer

To secure the best Heroku talent, dodge these common pitfalls that can deter candidates from applying.

1. Being vague about Heroku-specific tasks

Avoid broad or generic descriptions of responsibilities. If you're vague about the Heroku-related tasks, candidates might not recognize the opportunity to utilize and grow their specific skill set. Instead, clearly state the Heroku-related tasks such as managing add-ons, handling app scaling, or setting up and maintaining Heroku pipelines.

2. Underestimating the importance of Heroku's ecosystem

Don't overlook the need for familiarity with the broader tools and services that integrate with Heroku, like Salesforce, AWS, and GitHub. Failing to recognize the Heroku ecosystem's importance can make the job seem disconnected from the current tech environment. Candidates should have experience not just with Heroku but also with its ecosystem.

3. Ignoring the balance between Heroku and other technologies

Don’t focus solely on Heroku to the detriment of associated skills. Overemphasizing Heroku might lead to overlooking a developer's ability to work with other critical technologies. A well-rounded developer should also have expertise in the programming languages and frameworks commonly used with Heroku, like Ruby on Rails or Node.js.

4. Omitting details on collaboration 

Remember that your Heroku developer won’t work in isolation. Neglecting to mention teamwork can result in hiring a developer who may struggle with your company's collaborative dynamics. Be sure to mention the need for collaboration with other departments.
