Our award-winning products - SignNow, pdfFiller, DocHub, altaFlow, Instapage, and US Legal Forms - serve over hundreds of millions of users and more than one million customers worldwide, helping organizations of every size digitize processes, improve efficiency, and transform how they work.

We're in an exciting phase of growth and transformation, with teammates in more than 20 countries across three continents and main hubs in the United States, Poland, Romania, Ukraine and Philippines.

At airSlate, we're building value for customers and a culture where growth and innovation go hand in hand. We're looking for people eager to shape products, scale a company, and thrive in a fast-moving environment.

About pdfFiller team:

We are a passionate and ambitious team of 120+ people on a mission to succeed with our online PDF creator and editor - pdfFiller.

pdfFiller empowers over 10 million users every month to create and edit PDFs, send them for signing, and securely store documents within a single application. Offering unlimited storage, unlimited templates, and cross-platform integration, pdfFiller is the only PDF editor needed to get your document done.

And now, we are looking for a Fullstack Software Developer who is prepared to contribute to the next chapter of our company's growth.

The person will join the Power Charlie team within the MyDocs unit and work on two product tracks: AI assistant development and a document completion workflow that lets users create one document, gather multiple structured responses, and act on the results.

What you'll be working on:

• Driving AI coding agents to deliver product features - writing clear, context-rich tasks that cover architecture, team standards, and acceptance criteria
• Taking full ownership of every feature end-to-end - from clarifying requirements and understanding the problem, through delivery to production, to monitoring edge cases post-release
• Conducting code and documentation reviews to ensure quality, share knowledge, and maintain consistency across the codebase
• Participating in duty rotations - monitoring production systems, responding to incidents, and keeping services available
• Building AI-powered features that improve UX for thousands of users tackling real business challenges
• Growing technically inside a team with a strong engineering culture, clean architecture, and a high bar for delivery

What we expect from you:

• 3+ years of commercial experience as a software developer
• Hands-on experience with agentic development workflows
• Practical commercial experience with Golang, Node.js, or PHP
• Hands-on experience with JavaScript, TypeScript, and React
• Solid SQL and experience with relational databases (MySQL, PostgreSQL, or similar)
• Working knowledge of Docker for application development and deployment
• Practical experience with testing methodologies
• At least basic knowledge of DevOps, CI/CD, AWS, and cloud-native solutions
• Ability to write technical documentation using approaches like the C4 model and ADRs
• Strong task decomposition and prioritization skills
• Fluent English, written and spoken
