Description
Software Engineer / Senior Software Engineer — Platform
Engineering | Level: mid / senior
Location: Krakow, Poland
Hybrid (4 days/week in office)
About the Role
We’re looking for a passionate Software Engineer / Senior Software Engineer, Platform to help build the technical foundations that power a global, cloud-based SaaS platform.
You’ll join a high-performing Platform Engineering team responsible for the infrastructure, services, tooling, and developer experience that product engineering teams rely on every day.
This is not a tickets-in, tickets-out role.
The Platform team owns its roadmap, chooses the problems worth solving, and measures success by how much faster, safer, and more reliably the wider engineering organization can deliver.
You’ll work across internal libraries, shared backend services, CI/CD, developer tooling, and observability—while collaborating with engineering teams across multiple countries and time zones.
What You’ll Work On
Build and maintain shared libraries and SDKs covering areas such as authentication, logging, configuration, gRPC clients, and error handling.Develop shared backend services and internal APIs.Improve developer experience through service templates, scaffolding, and local-development tooling.Build and maintain fast, reliable, and secure CI/CD pipelines using GitHub Actions.Develop and evolve observability across metrics, logs, traces, dashboards, and alerts.Partner with product engineering teams to solve complex technical problems, unblock integrations, and review designs.Participate in an on-call rotation and respond to production incidents.Build scalable cloud platforms supporting multiple SaaS applications.
Tech Stack
You’ll work with modern technologies including:
TypeScript · Node.js · NestJS · PostgreSQL · AWS · Kubernetes · Terraform · GitHub Actions · DynamoDB · SQS · Kinesis · Lambda · Prometheus · Grafana · OpenTelemetry · Datadog
What We’re Looking For
3+ years of experience building backend services with TypeScript / Node.js, ideally with NestJS in production.Strong software engineering fundamentals, including an understanding of CPU, memory, I/O, concurrency, and performance bottlenecks.Experience using AI-assisted development tools effectively, with the technical judgment to review, validate, and improve AI-generated code.Working knowledge of PostgreSQL, including schema design, migrations, and query analysis.Familiarity with AWS services such as DynamoDB, SQS, Kinesis, and Lambda.Experience working with CI/CD pipelines and understanding release and promotion flows.Experience with modern observability tooling such as Prometheus, Grafana, OpenTelemetry, Datadog, or similar.A willingness to learn across a broad and constantly evolving platform landscape.A focus on writing clean, reusable code that other engineers can understand and build upon.
For Senior-Level Candidates
For the senior level, we’re looking for demonstrated ownership of production systems and the ability to set technical direction.
You should have experience with:
PostgreSQL performance tuning, including query plans, indexing, hot tables, and slow migrations.Designing and building CI/CD strategies, including release flows, artifact promotion, and security.Building observability from the ground up, including SLIs/SLOs, dashboards, and effective alerting.Acting as a technical voice in cross-team discussions.Mentoring engineers and raising engineering standards.
What Will Make You Successful
Strong ownership and accountability.Excellent communication and collaboration skills.Comfort working with distributed, multicultural teams.A strong sense of urgency and ability to deliver in a fast-paced environment.Exceptional attention to detail and commitment to quality.Strong problem-solving skills and a customer-first mindset.Experience collaborating across multiple time zones, including GMT, IST, and PST.
Why Join?
You’ll have the opportunity to work on high-leverage platform engineering problems that directly enable other engineers to build and ship better software.
If you enjoy solving complex infrastructure and developer-experience challenges, building systems used by many teams, and taking genuine ownership of technical outcomes, we’d love to hear from you.
