About Us

Fiska is an innovative payments infrastructure company enabling SaaS platforms to seamlessly connect to payment networks and monetize transactions. Our solutions empower SMB SaaS commerce platforms in a fast-growing market with rapid adoption of integrated payments.

We're a small, highly motivated team of ambitious builders. We're profitable and not dependent on external funding. We focus on results, not titles.

The Role

We're looking for a Software Engineer to join our team and build the next generation of payment infrastructure for SaaS platforms. You'll work closely with product and cross-functional teams to design, implement, and scale core systems that power seamless payment experiences. From APIs to integrations, you'll help bring new capabilities from concept to production in a fast-paced, high-trust environment.

Responsibilities:

• Design, develop, and maintain scalable backend services and APIs for payment processing and partner integrations using ASP.NET.
• Collaborate with product managers and other engineers to define requirements, architecture, and technical specifications.
• Write clean, maintainable, and well-tested code that meets high standards of quality and performance.
• Contribute to the full software lifecycle—from planning and design to deployment and monitoring.
• Stay up to date with emerging technologies, best practices, and trends in SaaS and payments infrastructure.
• Participate in code reviews, technical discussions, and continuous improvement initiatives.

Requirements

• 3–5 years of experience as a software engineer, ideally in SaaS or fintech
• Proficiency in ASP.NET and familiarity with C#.
• Strong understanding of APIs, cloud infrastructure, and modern development workflows.
• Highly motivated, adaptable, and comfortable working in a dynamic, fast-moving environment.
• Highly motivated, ambitious, self-starter with resilience and adaptability.
• Comfortable with change, wearing multiple hats and figuring things out.

Nice-to-haves:

• Bachelor's degree in Computer Science, Engineering, or equivalent.
• Experience working with payment systems or financial APIs.
• Familiarity with credit card payment processing, tokenization, or PCI compliance.
• Experience with containerized environments (Docker, Kubernetes) and cloud platforms (AWS, GCP).
• Experience with AI Tools (Cursor, Windsurf, ect).

Why Join Us?

• Make an impact in a small-scale, ambitious team.
• Be a part of a culture where you are a name and not a number, or a title
• Profitable, stable business in a rapidly growing market.
• Flexible work conditions, with the preference for a candidate excited to be in our downtown office 2–3 days/week.
• Competitive compensation package.
• Unlimited PTO (uncapped paid time off).

Before You Apply

Fiska isn't for everyone. If you're looking for easy wins or a comfortable ride, this won't be the place. But if you're a high-output, high-trust professional with fire in your gut and the kind of drive that doesn't quit at 5, we encourage you to apply.

Our Company Perks:

• Flexible work location and work hours around partners' needs.
• RRSP matching
• Flexible time-off policies with the week between Christmas to New Year's provided off.
• Company-wide retreats annually.
