Staff Software Engineer (Backend/Fullstack)

📍 Remote | Full-time


About the role

We are looking for a Staff Software Engineer to join a strong, passionate engineering team and help shape the future of our commerce platform. This is a backend-focused role with a meaningful impact on product architecture, scalability, and integrations across the e-commerce ecosystem.


You will work on core systems such as subscriptions engine and integrations with major e-commerce cart platforms. While backend expertise is key, frontend skills are a strong plus.

You’ll collaborate closely with product, platform, and integrations teams to design scalable, reliable systems and influence technical direction across the organization.


Please note, this is a contract-to-hire opportunity with the option to convert to full-time after 3–6 months. Compensation during the contract period will be paid monthly.


What you’ll do

  • Design and develop core backend systems, including subscription, billing, and tax services.

  • Build and scale integrations with major e-commerce platforms (e.g., Shopify, Magento, WooCommerce, SFCC).

  • Architect reliable, high-performance APIs and distributed systems.

  • Drive technical decisions and contribute to long-term platform architecture.

  • Mentor engineers and raise engineering standards across teams.

  • Collaborate with product, infrastructure, and other teams to deliver complex features end-to-end.

Skills Required

  • Strong experience in backend engineering at scale.

  • Proficiency in at least one of the following languages: Go, C#, or Java.

  • Experience with SQL and NoSQL databases.

  • Experience designing distributed systems, APIs, and integrations.

  • Knowledge of cloud infrastructure and microservices architecture.

  • Ability to think at the system and product level, not just implementation.

  • Experience working in complex, cross-team environments.

Preferred Qualifications

  • Frontend experience (React, TypeScript, etc.).

  • Experience with e-commerce, payments, subscriptions, or marketplaces.

  • Experience with event-driven architecture (Kafka, RabbitMQ, etc.)

  • Understanding of compliance, privacy, and security best practices in fintech.

  • Familiarity with infrastructure as code and CI/CD pipelines (Terraform, GitHub Actions, etc.)

Why Bolt?

  • Work in a highly skilled engineering team with a strong technical culture.

  • Solve complex problems in payments, commerce, and integrations.

  • Influence architecture and technical strategy.

  • Opportunity to learn from experienced engineers and grow further.

  • Real impact on a product used by merchants globally.
