Our team is our best asset. We work with extremely smart and talented individuals, who all enjoy a high degree of responsibility and independence in structuring their work.
Do you think you have what it takes to be part of Echobox? We'd love to hear from you.

About the Role:
You will work closely with our Product team and Data Scientists to define and execute on the future path for our products.

Key Responsibilities:
- Take ownership of designing, developing, and shipping high-quality software solutions for our SaaS platform. Focus on delivering results that directly impact the business and customers, all whilst meeting launch deadlines.
- Collaborate closely with product and engineering teams to quickly identify key customer needs and market opportunities, turning them into actionable, efficient solutions.
- Break down complex technical problems and deliver simple, impactful solutions. Prioritize speed and execution while ensuring the software remains robust and scalable.
- Lead by example—write clean, maintainable, and high-performance code, and always be the first to push for shipping quality features quickly.
- Proactively mentor junior engineers, sharing knowledge and driving the team forward with a hands-on approach. Help them grow by guiding on real-world problem solving.
- Move fast, ensuring that features are delivered rapidly while maintaining a focus on scalability, security, and system performance.
- Continuously optimize and improve existing systems and software. Don’t just wait for issues to arise—anticipate challenges and take action before they become roadblocks.
- Drive technical decision-making with a focus on results. Make the tough calls quickly and without hesitation, cutting through unnecessary processes to get things done.
- Effectively communicate technical decisions and outcomes, providing clarity and direction for both technical and non-technical stakeholders.

Requirements:
- A degree in Computer Science, Engineering, or a related field, or equivalent hands-on experience in engineering.
- 5+ years of experience building software in a fast-paced, results-driven environment—preferably with SaaS platforms.
- Proficiency in full-stack development and experience with modern languages (e.g., Java, Typescript/JS, mySQL/Posgres, MongoDB), always ready to dive in and code when needed.
- Strong background in cloud technologies (AWS) and microservices architectures. You know how to make things work, no matter the scale.
- Experience with Agile development and CI/CD pipelines. You know how to ship code quickly, with a focus on continuous delivery.
- Proven ability to work cross-functionally and push for action across product, design, and business teams.
- A strong, data-driven mindset that allows you to make quick decisions and measure the success of your work effectively.
- Clear, concise communicator with the ability to explain technical issues to anyone and get things done without unnecessary back-and-forth.
- Fluent written and spoken English.

Preferred Requirements:
- Experience in a fast-paced, B2B SaaS environment where moving quickly and delivering value is key.
- A get-things-done mentality—no time for bureaucracy, just results.
- Familiarity with emerging technologies like AI and Machine Learning, and a passion for using them to shape the future of SaaS.
- Excellent organisational, analytical and influencing skills, with proven ability to take initiative and build strong, productive relationships.
- Experience working with cross-functional teams within a software organisation.
- You’re entrepreneurial; you don’t need direction; you're self driven.
- Be able to easily switch between thinking creatively and analytically.
- A natural leader who earns trust with a collaborative, yet persuasive style.
- An interest in Artificial Intelligence and the future of the publishing industry.

Benefits:
