About the role

We are looking for a Senior Backend Engineer to build backend features for payment flows and reduce technical debt across Java services.

The mandatory requirements are 4+ years of backend engineering experience, payments, fintech, or billing domain experience, Kotlin, Python, and an upper-intermediate English level.

Must haves

  • 4+ years of backend software engineering.
  • Building and operating production backend services at scale.
  • Strong proficiency in Java as the primary programming language, with Kotlin and Python as complementary skills.
  • Hands-on experience with RESTful and GraphQL APIs, microservices, and event-driven systems.
  • Payments, fintech, or billing domain experience, including gateways, processors, or PSPs.
  • Writing unit, integration, and contract tests.
  • Agile/Scrum, sprint-based delivery.
  • Ramps quickly on an existing codebase with minimal guidance.
  • Git-based version control and code review (GitLab).
  • GitLab CI/CD pipelines.
  • Relational databases (MySQL) and SQL.
  • Distributed systems: message queues, async processing, eventual consistency.
  • Jira for task and sprint tracking.
  • Built end-to-end backend payment flows (charge, refund, dispute, webhooks) in production.
  • Experience in legacy service refactoring/migration with regression testing.
  • Experience resolving production incidents in payment or billing systems.
  • Experience designing internal APIs consumed by multiple downstream services.
  • Upper-intermediate English level.

Nice to haves

  • Experience in a large enterprise engineering org.
  • Spring Boot, Gradle, service mesh.
  • PCI-DSS compliance, payment security, or financial data handling.
  • Observability tooling (Datadog).
  • Open-source contributions or a portfolio of shipped payment features.

What you will do

  • Implement new backend features for payment flows.
  • Drive technical-debt reduction, including refactoring legacy services, improving test coverage, and modernizing APIs (e.g., deprecated API migrations).
  • Write clean, well-tested, production-ready code that meets Indeed's engineering standards and merges to main with passing CI/CD pipelines and peer-review approval.
  • Deliver against multiple initiatives within agreed sprint cycles. Participate in code reviews, design discussions, and sprint ceremonies alongside full-time Payments engineers.
  • Collaborate with product managers, partner teams, and fellow engineers to clarify requirements and deliver end-to-end solutions.
  • Produce documentation for owned workstreams — designs, API specs, KT docs, and runbooks — to support long-term maintainability.
  • Ensure a smooth hand-off to the full-time engineering team at the conclusion of the engagement.

Perks

  • Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget
  • Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews
  • Flexibility: work 100% remotely with flexible hours that support focus, autonomy, and a healthy work rhythm
  • Meaningful, modern projects: build impactful products using modern technologies alongside global teams and leading brands
  • Collaborative culture: join a supportive environment with zero micromanagement where ideas are welcomed and contributions are recognized

FAQ

Have any questions?

What is the work format and schedule?

We are a remote-first company, so all our positions are remote. Schedules are flexible, but the main requirement is to have an overlap with your client’s schedule to ensure smooth collaboration. Specific details depend on the project and are discussed during the interview process.

What level of English is required?

We look for Upper-Intermediate (B2) proficiency or higher. Since you will be collaborating with international teams and global clients (including Fortune 500 companies), English is a part of your daily work.

Does AgileEngine provide work equipment?

It depends on your location. We provide equipment in Ukraine, Poland, Argentina, Colombia, Mexico, Brazil, Guatemala, Portugal, Spain, and India. In the USA, equipment is usually provided by the client; otherwise, you will be expected to use your own setup.

What opportunities for professional growth do you offer?

We support continuous growth through personalized development paths tailored to each expert. Also, you can expect:

  • An annual learning and development budget
  • Internal workshops, tech talks, and mentorship programs
  • Opportunities to switch projects or grow into new roles over time

What does a typical team look like, and what tools do you use?

Teams vary by project, but you’ll usually work with a mix of experts across different fields, along with a delivery or project manager who supports collaboration and onboarding.

For day-to-day work, teams commonly use tools like Jira and Google Workspace, along with communication platforms such as Google Chat. Depending on the client, you may also work with Slack, Confluence, Notion, or similar tools.
