The Role at a Glance- Title: Senior Network Engineer
- Employer: Fully remote role supporting a leading North American bank
- Contract: B2B, 34,000–38,000 zł net + VAT per month
- Location: Open only to candidates based in Poland
- Hours: Work US Eastern business hours (15:00–23:00 Poland time)
We're hiring experienced network engineers (6+ years) to join the IT infrastructure team at a top North American bank — directly supporting the operations and development of financial trading systems. You'll be part of the core IT infrastructure team, building and maintaining infrastructure for highly-performant, low-latency trading systems used across the firm.
Why Join Us?- Work on large-scale systems - routers, switches, low-latency trading infra supporting hundreds of physical and virtual servers.
- Collaborate with a world-class team of network engineers, DevOps engineers, and developers across North America and Europe.
- Enjoy a long-term, fully remote role.
- Competitive compensation and long term stability that only a bank can offer.
This role is critical to maintaining the performance, reliability, and security of the network infrastructure that supports the trading systems. You'll work across both on-premises trading infrastructure and cloud environments, ensuring seamless connectivity and secure access for business-critical systems. The position combines hands-on engineering with automation and infrastructure-as-code practices, solving complex problems through collaboration and technical expertise.
This is a fully remote role based in Poland. You will work directly with the bank while being contracted through a Polish partner company that provides local support and administration. The position requires strong English skills (spoken and written) to collaborate daily with colleagues in North America.
This role requires working during US Eastern business hours in order to be able to collaborate closely with other team members.
Only open to residents of Poland. Polish citizens, as well as legal residents with permission to work in Poland are welcome.
Successful candidates will need to pass a standard background check.
What we offer- Work that matters in the financial domain: Work on a trading system at an established financial institution, processing millions of transactions daily.
- Professional growth: Collaborate with smart, highly capable developers in a supportive and challenging environment.
- Direct collaboration: You will work directly with the bank's team in North America and in Poland.
- 1st-tier work: This is not a technical support or legacy maintenance role. The system is functional and is actively being built and you will take part in updating it. The people who built the system are still part of the team.
- Long-term commitment: This is not a fixed-scope or fixed-term outsourcing role; we value people who want to grow and contribute long-term.
- Fully remote work: Fully remote position based in Poland.
- Competitive Compensation: Above-average pay and ample time-off options.
- Apply: Send us your CV.
- Written screen: Answer a short set of written questions to show us how you think about networking.
- Interviews: A three-stage online process, one with a technical recruiter with latter rounds at the bank.
Successful candidates will need to pass a standard background check.
