Software Developer Java Backend & PostgreSQL expert

Do you enjoy building backend systems and understanding what really happens inside the database underneath them? Are you the developer your team turns to when a query slows down, a replica falls behind or a database upgrade needs planning? If you answer yes, then keep reading and see if your next career step could be with us at Remion.
Why choose us?
We are a work community of about 50 people where technical expertise, engineering spirit, helping others, and flexibility meet. Our team has a diverse background, ranging from professionals from large companies to recent graduates. We share a passion for solving technical challenges, a general interest in technology, strong professional pride, and a genuine goal for high-quality work.
Our development team of 30+ developers have their hands full, and we are on the search for a backend developer with strong PostgreSQL skills to join us. You will work on customer projects directly with our clients. Your goal is to develop, optimize, and maintain backend systems and the databases they rely on, to meet our customers' needs.
With us, you will have the opportunity to impact on our customers' businesses, and we value long-term customer partnerships. Customer relationships last for years, and projects are carried out as needed. Some of our customers have dedicated teams that work with the same customer continuously and for a very long period.
About the role
You will develop backend systems that receive and process large amounts of time series data from thousands of industrial devices and produce valuable information for our customers. Our Regatta IoT platform runs both on cloud platforms (AWS, Azure) and in customers' own data centers.
The role has two key areas:
Backend development (most of your time). You develop and maintain Java-based backend services and integrations in our customer projects and in our Regatta platform.

Database ownership (a dedicated share of your time). You are one of the owners of the self-hosted PostgreSQL/TimescaleDB environments we run for our customers. This includes a high-availability cluster (Patroni) in a customer's data center: monitoring, backups and restore testing, performance analysis, version upgrades and capacity planning. You will not be alone with this: you will work together with our developers and an experienced database consultant, and you help us grow this expertise within the team.

We aim to work in an AI-assisted development model where intelligent agents are a key part of the software development process. Developers act as architects, supervisors, and quality owners. We value experience working alongside AI tools and coding agents, where you guide execution, review outputs critically, and ensure architectural integrity.
We value
Trust – Trust at Remion is multi-directional. Colleagues trust each other and the management, and the management equally trusts the employees. We believe that trust creates a solid foundation for our operations.

Flexibility – Flexible working hours and location-independent work are everyday matters for us. The management is always ready to discuss and be flexible on matters important to the employees.

Helping others – Helping and asking for help is everyday for us. There may not be written instructions for everything, but it is guaranteed that when asked, help and instructions are always available.

Are you the one we are searching for?
You have several years of experience in backend development, and you have worked with PostgreSQL in production and not only as an application database, but also from the operations side. You can read an execution plan, you know why autovacuum matters, and you have taken part in database upgrades, backups or restores. You are curious to go deeper, document what you learn and share it with your colleagues.
Additionally, the Industrial Internet of Things is a familiar concept to you. Knowledge of the engineering industry is considered an advantage. You have natural precision and eye for software design. We hope you are proactive, ask when you get stuck, and are ready to help colleagues.
Required
Backend development, preferably Java 17+ (Maven, Jakarta EE or Quarkus)

Strong SQL and PostgreSQL skills in production: query and index optimization, execution plans, vacuum, roles and permissions

Experience with PostgreSQL operations: backups and restores, upgrades, replication or monitoring

Linux server environments

Considered an advantage
TimescaleDB or other time series databases (hypertables, compression, retention)

PostgreSQL high availability (Patroni or similar) and backup tools such as pgBackRest

Ansible or other infrastructure automation

Docker / Podman, Kubernetes

Datadog or other monitoring tools

AWS and Azure IoT solutions

AI tools and agents

Typescript

With your expertise and skills, you are a part of creating good customer experience. Your work contributes to how the customer can utilize the data in their devices and derive benefits for their business, and to keeping that data safe and available.
Ideally, we're looking for someone based in the Pirkanmaa area who enjoys a strong office culture and likes coming to the office.

We're also putting a lot of effort into developing our office culture and making the office a place where people genuinely enjoy spending time.
