Descrição da oferta de emprego

Senior Java Backend Engineer at Powerdot, Inc.

Employer: Powerdot, Inc. Employment type: Periodo Integral. Location: Porto, Portugal.

About this Role

Charging your car should be as easy as charging your smartphone. And so for that to happen, chargers need to be available where people naturally spend their days.

Our mission is as simple as it is ambitious: Accelerate Sustainable Mobility by investing in, installing, and operating EV chargers with a cutting‑edge business model. We help businesses find the right charging solutions for their customers. Today, we've partnered with over 1,200 businesses across Portugal, Spain, France, Belgium, Luxembourg, and Poland, with more than 2,200 contracted locations.

We are, first, Partner Obsessed — creating bespoke solutions to better serve our partners’ customers. We love the challenge of making EV charging simpler, readily available, and integrated with diverse retail and service experiences. And we are all about growing — expanding our network, our partners' businesses, and the professional development of our team, all while driving the EV ecosystem forward.

We seek empowered top performers who share our mission and values, and who are ready to think disruptively and join our exciting journey.

Day-to-day responsibilities

• Collaborating with cross-functional teams — understanding their requirements and ensuring backend services meet the needs of the business and our partners.
• Designing and developing microservices architectures — using Java and Spring Boot to build modular, scalable, and maintainable services.
• Implementing AWS services — leveraging EC2, S3, Lambda, and RDS to ensure scalable, efficient, and cost-effective operations.
• Creating and optimizing database systems — designing both relational and non-relational databases, ensuring data integrity, performance, and reliability.
• Working with messaging systems — using RabbitMQ and Kafka for seamless, resilient inter-service communication.
• Utilizing containerization and orchestration — employing Docker and Kubernetes to streamline development, deployment, and scaling processes.
• Maintaining high standards of code quality — following best practices around reliability, security, and testability, and upholding rigorous engineering standards.
• Providing technical guidance and mentorship — supporting junior engineers through code reviews, pairing sessions, and knowledge sharing.

Qualifications

• Strong experience in microservices architectures — you've designed, built, and deployed production‑grade microservices using Java and Spring Boot.
• Proficient with AWS services — hands‑on experience with EC2, S3, Lambda, and RDS in production environments.
• Deep understanding of database systems — skilled in database design, optimization, and performance tuning across both relational and non‑relational databases.
• Familiarity with messaging systems — practical experience with RabbitMQ and Kafka for asynchronous, event‑driven architectures.
• Knowledge of containerization and orchestration — comfortable with Docker and Kubernetes in development and production workflows.
• Strong problem‑solving skills — you break down complex technical challenges and drive them to resolution, independently or as part of a team.
• Excellent communication skills — you collaborate effectively with cross‑functional teams and can convey technical concepts clearly to non‑technical stakeholders.
• Experience in the EV charging industry is a plus but not required.

Kind of Energy We're Looking For

• We’re not into titles, egos, or corporate buzzwords. We’re into people who make things happen.
• You lead and listen. Whether steering initiatives or supporting teammates, you bring others with you and keep communication wide open.
• You own your stuff. You don’t wait for instructions: you see an opportunity, grab it, and make it better than anyone expected.
• You’ve got a green heartbeat. Sustainability isn’t just cool, it’s core. You care about doing work that leaves the world a little better than you found it.
• You balance hustle with humanity. You love the buzz of in‑person teamwork, but you also know when to recharge.
• You grow on purpose. You’re hungry to learn, to stretch, and to build something meaningful, not just rack up LinkedIn bullet points.

Benefits

• Private health insurance coverage
• Gym membership to help you stay active
• Flexible working hours: you own your time
• Annual offsite to celebrate achievements and connect with colleagues
• Regular team‑building activities with your local team
• English training — as English is our language used to connect with all markets and teams
• Free office snacks, unlimited coffee, and meal allowance for every worked day
• Special discounts for charging your electric vehicle

Our Promise To You

The best solutions come from different voices. We’re building a culture where inclusion, respect, and equal opportunity aren’t policies — they’re lived every day. At Powerdot, everyone has the space to speak up, challenge the status quo, and make a difference. Your voice powers the future — literally.
