We are looking for an experienced back-end software engineer to join us; you would deep-dive on challenging technical problems, build scalable solutions and identify performance bottlenecks, iterate quickly and deliver incremental value and thrive in a collaborative team environment. Your engagement would usually start with requirements clarification with the product manager or our partners. You will have the opportunity to put the best of your ideas to the design and prove your coding skills in actual implementation.

We primarily use micro-services written in GO on the back-end. However, we have legacy code in Ruby on Rails and you might encounter TypeScript too. We have data stores built on MySQL, PostgreSQL and various NoSQL databases like AWS DynamoDB. We are transitioning our data loading layer to use GraphQL.

Location and Eligibility

While we are remote-friendly, we remain an "office-centric" company. This role is categorized as hybrid and it is expected you live in a reasonable proximity to the office in Prague so you would be able to connect with your team on weekly regular basis, attend in-person meetings and company events. This is a full-time, permanent role, not eligible for contractors and for work from other countries.

The offer is contingent upon successfully passing the background screening process as required by law.

Compensation and Scope

Compensation for this role is structured and published in a dedicated band. Specific factors such as location, experience, and performance may influence the final offer within the defined range.

Key Responsibilities

Setting architecture for services that connect Outreach to external email providers at scale.

Designing data pipelines that convert communication events into insights for forecasting accuracy.

Coordinating with partners to align new features with roadmap goals and integration standards.

Refactoring legacy Ruby code to improve reliability while maintaining compatibility with current flows.

Reviewing telemetry to detect slow queries and latency issues before they affect customer experience.

Shipping incremental improvements that keep sync processes reliable across MySQL, PostgreSQL, and DynamoDB.

Guiding implementation of GraphQL for data loading while preserving existing API contracts.

Mentoring engineers on coding practices that keep services maintainable and testable.

Requirements

You have at least 3 years and up to 5 years of professional software engineering experience.

You can write server logic in GOlang and understand how concurrent systems handle high load.

You are comfortable reading legacy Ruby on Rails code and adapting it safely.

You know TypeScript enough to read and modify front end interactions when necessary.

You understand data modeling across MySQL, PostgreSQL, and NoSQL stores like AWS DynamoDB.

You can work under the condition of passing background screening as required by law.

Nice to Have

Experience contributing to open source projects that involve communication protocols.
