About PhantomBuster

PhantomBuster is a web automation SaaS that allows businesses to grow faster. We enable thousands of companies to boost their growth by finding and connecting with their ideal customers seamlessly.

Founded in 2016, PhantomBuster developed a toolbox of over 120 flows (Phantoms) to help businesses scale their sales and marketing processes. We allow our users to automate finding and enriching data about their potential customers and leverage that data to connect with them.

Today, we are quickly moving from a catalog of automation tools to an AI-powered Sales coach product. We need to empower and expand our technical teams to ensure this transformation is seamless, fast, and powerful.

About the Role and the Team

Accelerating the growth of our company, our Buster Engineering Department is a group of engineers passionate about great user experience and smooth interfaces. As a member of this team, you cooperate closely with the Product team to deliver the best possible experience to our users.

We run three squads of experienced engineers and tech leads (Logan, and Antoine), supported by two Engineering Managers (Lionel and Louis). You will join one of our autonomous product Squads consisting of 3 to 5 Software Engineers, a Squad Lead, a Product Manager, and a Product Designer. We are looking for an experienced and autonomous Software Engineer with solid technical skills and a user-oriented mindset. As we search for a seasoned Front-end professional, we wish for someone who has some back-end knowledge and is eager to use it.

We are now hiring to strengthen the team’s technical leadership, provide a senior partner to our most senior Staff Engineers, and champion the thoughtful use of AI in engineering practices. This role is critical to maintaining continuity, raising technical standards, and guiding long-term architectural direction.

• Node and databases as Redis and PostgreSQL

• Cloud-based architecture on AWS

• DevOps tools such as Docker, Ansible

• CI/CD thanks to GitHub Actions and CircleCI

• Identify opportunities to leverage AI internally (developer productivity, monitoring, anomaly detection)

Who You Are

  • Experienced with React.js or any modern framework;

  • A clear understanding of REST/JSON APIs;

  • Strong knowledge of HTML and CSS;

• You also have backend technologies knowledge and wish to use it

AI Guidelines

At PhantomBuster, we use AI tools daily to build things faster. As the use of AI in recruitment might have multiple implications, we want to be transparent about how we might use it and how we expect you to use it during our recruitment processes.

How we use AI:

• Draft and refine job descriptions and case studies,

• Draft emails during the process,

• Find interview timeslots,

• Summarize interview notes,

How we don't use AI:

• Assess your CV or profile,

• Evaluate interview performance,

• Conduct interviews,

• Grade technical tasks or case studies.

You interact with humans. Period.

We invite you to use AI throughout the recruitment process. However, we want to meet YOU, not machine-generated responses. Your unique perspective matters so much more than perfect AI answers.

Feel free to use AI to:

• Research our company, team, or product,

• Refine your CV, portfolio, or LinkedIn profile,

• Prepare for interviews and brainstorm potential questions,

• Polish your case study or presentation,

• Draft emails to us,

Let us know throughout the process how you used AI - we are curious to learn.

Don't use AI to:

• Search for answers during interviews (unless we ask),

• Create documents (CV, portfolio, presentation) from scratch without your input,

• Build case studies or technical tests without your personal touch.

If you have any questions, we would love to hear from you → mateja.jokovic.ext@thephantomcompany.com
