Mainframes are large computers with particularly high processing power and are often used for critical tasks like bulk data processing or enterprise resource planning. In this role, you may help ensure all new software is fully backward-compatible, monitor system performance, isolate errors, and work collaboratively with other developers as needed. Most mainframe developers work for larger companies. As a remote employee, you use virtual office software, phone, chat, or email to remain connected to other employees.

Familiarity with tools such as IBM z/OS, DB2, CICS, and version control systems is typically required, along with relevant certifications. Excellent problem-solving abilities, independent work ethic, and effective virtual communication are standout soft skills for this remote role. These skills ensure smooth maintenance, modernization, and support of critical legacy systems in distributed teams.

Effective communication is key, so regular check-ins and proactive status updates help ensure alignment on project goals and troubleshooting efforts. Many companies use agile methodologies, which means you'll likely participate in daily stand-ups and sprint planning sessions remotely. While time zone differences can be a challenge, flexible scheduling and clear communication protocols are common strategies to keep everyone connected and productive.

Job description

ABOUT THRIVE MARKET
Thrive Market was founded in 2014 with a mission to make healthy and sustainable living easy and affordable for everyone. As an online, membership-based market, we deliver the highest quality healthy, and sustainable products at member-only prices, while matching every paid membership with a free one for someone in need. Every day, we leverage innovative technology and member-first thinking to help our over 1,700,000+ members find better products, support better brands, and build a better world in the process. We are also a Certified B Corporation, a Public Benefit Corporation, and a Climate Neutral Certified company.
Join us as we bring healthy and sustainable living to millions of Americans in the years to come.
ABOUT THRIVE MARKET
At Thrive Market, Product Engineering builds the systems members touch every day, from the home page through checkout, account, and renewal. You'll work closely with Product, Design, and Data to ship features that drive real outcomes for our members and the business.
We are not looking for a programmer or a language specialist, we are looking for an engineer. Someone with strong CS fundamentals, great OO, great relational data modeling, and a systems mindset. Someone who reaches for architecture, patterns, and platforms before they reach for syntax, and who picks the right tool for the job rather than the one they know best. Communication is concise and high-level; orientation is big-picture without losing the details that matter.
RESPONSIBILITIES:
  • Own the architecture and evolution of your pod's systems end-to-end.
  • Make system-level calls on when to introduce eventing (Kafka, SQS), workflow orchestration (Temporal, Airflow, DAGs), caching, async pipelines, or new services, and when not to.
  • Design for horizontal scale and low, uniform latency under real Thrive traffic patterns.
  • Decompose existing services into scalable components where it materially helps; avoid decomposition for its own sake.
  • ie engineering decisions to outcomes. Instrument what you build; defend what you ship with data.
  • Test-driven from the start. Quality, reliability, and observability are first-class, not afterthoughts.
  • Bring Product and Design options and a recommendation, not a single path.
  • Raise the bar on the team's architectural and systems thinking: mentor, review, challenge, elevate.
  • Own the SLAs for the surfaces your pod runs.
QUALIFICATIONS
  • 5+ years building and operating high-traffic, customer-facing systems.
  • Strong CS fundamentals. Strong object-oriented design. Strong relational database design and reasoning.
  • Fluency at the system and cloud level: eventing (Kafka, SNS, SQS), workflow orchestration (Temporal, Airflow, DAGs), distributed systems tradeoffs, caching, async pipelines, idempotency, backpressure.
  • Comfort working across multiple languages and stacks; language is a tool, not an identity. Our stack today includes PHP/Magento on the backend and React/Next on the frontend, on AWS; the right hire is comfortable moving between layers.
  • Working knowledge of AWS (Lambda, S3, CloudWatch, SQS, etc.) and clear reasoning about tradeoffs between relational, document, and wide-column stores.
  • Track record of shipping high-impact, customer-facing features in production at scale.
  • Communicates concisely and at the right altitude; defaults to options + recommendation, not exhaustive detail.
  • Big-picture orientation. Reasons about systems and outcomes; does not get lost in syntax.
  • Member-first. Prioritizes Customer, Team, and Business consistently.
  • Observability and monitoring experience (New Relic, Datadog, or similar) to maintain SLA, Apdex, and error rate.

BELONG TO A BETTER COMPANY
  • Comprehensive health benefits (medical, dental, vision, life and disability)
  • Competitive salary (DOE) + equity
  • 401k Employer Match
  • 9 Days of Observed Holidays
  • Flexible Paid Time Off
  • Subsidized ClassPass Membership with access to fitness classes and wellness and beauty experiences
  • Ability to work in our beautiful office in Playa Vista
  • Free Thrive Market membership with exclusive employee discount
  • Coverage for Life Coaching & Therapy Sessions on our holistic mental health and well-being platform

We're a community of more than 1 Million + members who are united by a singular belief: It should be easy to find better products, support better brands, make better choices, and build a better world in the process.
At Thrive Market, we believe in building a diverse, inclusive, and authentic culture. If you are excited about this role along with our mission and values, we encourage you to apply.
