About the Role

We’re looking for a skilled Java Developer to join our Product Marketing team and help showcase the real-world technical value of our high-performance database technology. In this unique role at the crossroads of product, marketing, and sales, you’ll develop open-source benchmarking tools and customer-focused demos that highlight Aerospike’s performance, resilience, and scalability in real-world scenarios. Your work will be central to how we communicate technical value in the market, empowering our marketing team with precision storytelling and enabling our sales team to demonstrate value effectively throughout the sales cycle. You’ll collaborate closely with a cross-functional team, gaining hands-on exposure to the full lifecycle of a high-growth technology company, from building the product, to defining its value, to taking it to market. This role will prepare you for strategic positions that demand a balance of technical depth and commercial awareness. You’ll be the primary developer for this initiative, working under the guidance of a manager who is also a hands-on developer. Expect regular code reviews, design discussions, and mentoring. We’re not looking for decades of experience, what matters is your ability to write solid, maintainable Java code, reason about your work, and clearly explain your results.
