ABOUT MARKETTIME

MarketTime https://www.markettime.com is a growing B2B ecommerce SaaS company helping businesses sell smarter and faster. Our multi-tenant platform powers enterprise customers across multiple industries, processing sensitive financial data - including credit card payments - while maintaining rigorous PCI DSS compliance.

Built on a scalable cloud-native architecture with robust public APIs and a MySQL-backed data platform, we deliver secure, reliable, and high-performance commerce solutions that our customers depend on every day.

We're a fully distributed engineering team that values ownership, collaboration, continuous improvement, and building software the right way.

ABOUT THE ROLE

We're looking for a Senior Backend Engineer (Java/Spring) to help design, build, and evolve our ecommerce platform. You'll work closely with Product and other engineers to solve complex technical problems, shape the architecture of our platform, and deliver secure, scalable solutions for our customers.

Beyond writing code, you'll mentor other engineers, drive engineering best practices, and help ensure our systems remain secure, reliable, and compliant.

TECH STACK

Java 25 • Spring Boot 4 • MySQL • REST APIs • AWS • GitHub Actions • Containers • SQS • Terraform • React

RESPONSIBILITIES

Design, develop, deploy, and maintain Spring Boot services powering our SaaS ecommerce platform.
Design secure, scalable, and highly available solutions that meet PCI DSS and other security requirements.
Design and build REST APIs that are intuitive, backwards-compatible, secure, and performant.
Collaborate with Product, QA, and other engineers throughout the software development lifecycle.
Design and optimize relational database schemas, queries, and data access patterns using MySQL.
Participate in architectural discussions and help drive technical decisions across the platform.
Write clean, maintainable, and idiomatic Java using modern language features and engineering best practices.
Champion engineering best practices including code reviews, automated testing, CI/CD, observability, and documentation.
Use AI-assisted development tools (e.g., Claude Code, Cursor, GitHub Copilot) to accelerate delivery, while owning the correctness, security, and maintainability of everything you ship.
Take ownership of features from design through production, including monitoring and operational support.
Work in small, incremental pull requests with a strong emphasis on code reviews, automated testing, and continuous delivery.
Help evolve our architecture by challenging assumptions and continuously improving how we build software.
Mentor and support engineers through technical leadership, design reviews, and pair programming.
Troubleshoot production issues and participate in an on-call rotation as needed.

REQUIRED QUALIFICATIONS

Operated as a senior engineer or technical lead on Java backend applications.
Strong expertise with Spring Boot 3+ and the broader Spring ecosystem.
Strong proficiency with modern Java, with new development targeting Java 25.
Ability to write clean, idiomatic Java using modern language features such as streams, lambda expressions, Optional, records, and pattern matching.
Experience with Hibernate/JPA or jOOQ.
Hands-on experience building and operating production workloads on AWS.
Proven ability to design and build RESTful APIs.
Strong SQL skills with MySQL or PostgreSQL.
Working knowledge of asynchronous messaging systems (SQS, RabbitMQ, ActiveMQ).
Experience building and deploying containerized applications.
Experience with GitHub Actions or other modern CI/CD platforms.
Hands-on experience using AI coding tools in professional work, with sound judgment about when to trust, verify, or discard their output, and a clear understanding of what data must never be shared with them.
Solid understanding of software design principles and distributed systems.
Excellent communication, collaboration, and problem-solving skills.
A track record of mentoring engineers and leading technical initiatives.
Self-motivated and effective working in a remote-first environment.

PREFERRED QUALIFICATIONS

Experience building and operating multi-tenant SaaS applications.
Familiarity with Infrastructure as Code using Terraform and GitOps practices.
Hands-on experience deploying and operating AWS services including VPCs, ALBs, EC2, ECS, SQS, and S3.
Working knowledge of React or Angular.
Understanding of payment processing systems, PCI DSS, and security best practices.
Background in ecommerce, fintech, or payment processing.
Familiarity with API security concepts including OAuth 2.0, JWT, authentication, authorization, and rate limiting.
Experience with test-driven development (TDD) and modern testing frameworks.
Experience establishing team practices for AI-assisted development (e.g., shared context and conventions files, review standards for AI-generated code, guardrails for sensitive data).
Exposure to C#/.NET is a plus.
