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 marketplace, we deliver high‑quality healthy and sustainable products at member‑only prices while matching every paid membership with a free one for someone in need. We are a Certified B Corporation, a Public Benefit Corporation, and a Climate Neutral Certified company.

Responsibilities

• Own the architecture and evolution of your pod's systems end‑to‑end.
• Make system‑level decisions on when to introduce eventing (Kafka, SQS), workflow orchestration (Temporal, Airflow, DAGs), caching, async pipelines, or new services.
• Design for horizontal scale and low, uniform latency under real Thrive traffic patterns.
• Decompose existing services into scalable components when materially helpful; avoid decomposition for its own sake.
• Engineer 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, object‑oriented design, 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. Current stack: PHP/Magento backend and React/Next frontend on AWS.
• Working knowledge of AWS (Lambda, S3, CloudWatch, SQS, etc.) and 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 and 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.

Benefits

• Comprehensive health benefits (medical, dental, vision, life and disability)
• Competitive salary (DOE) + equity
• 401(k) 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
