Senior Full-stack Engineer

About the team

You will be joining Gravity - our Core Platform team - the foundation that powers Sift's Digital Trust & Safety platform. We build the shared components, abstractions, and infrastructure that other engineering teams rely on to ship faster and smarter. Our customers are internal: we measure success by how much easier we make everyone else's job, and by keeping the platform maintainable, cost-effective, and built to last.

This role is intentionally full-stack. We need someone who can follow a problem wherever it lives - whether that's deep in backend logic or in a frontend component

BE Technical stack: Java, Dropwizard, GCP, Kubernetes, Kafka, BigTable, Spanner Graph DB, Postgres, Redis, gRPC, Python, Apache Airflow, Snowflake, BigQuery

FE Technical stack: ReactJS, React, React Query, React Router, Cypress, Jest, Storybook, SCSS

What you’ll do

• Design and evolve highly scalable, distributed platform components that can reliably serve as shared building blocks across Sift’s ecosystem, even under heavy load
• Deliver engineering solutions that address complex, cross-cutting customer and platform needs at scale, reducing the effort required for product teams to ship features
• Collaborate closely with engineers within Gravity and partner teams to introduce and maintain shared services, data models, and libraries that multiple teams depend on
• Continuously improve our platform engineering practices, tooling, and guardrails to simplify secure, compliant, and cost-effective operation of core systems

Opportunities for you

• Experience: Participate in highload platform and technical challenges to improve our core platform components, as well as building new capabilities
• Professional growth: tri-annual Growth Cycles instead of performance review;
• Knowledge Sharing: we have Tech Talks sessions. You will learn how to build components that handle petabytes of data and high fault tolerance
• Culture for innovations: you can try your ideas on our bi-annual Hackathon

What would make you a strong fit

• 5+ years of experience building distributed backend systems using Java;
• 3+ years experience designing/delivering highly-available services;
• 2+ years of experience building React-based FE applications, preferable platform areas
• Experience with data pipelines
• Degree in Computer Science or equivalent experience
• Strong communication & collaboration skills - a team-first, product-first mindset

Benefits and perks

• Competitive total compensation package
• 401k plan
• Medical, dental, and vision coverage
• Flexible lifestyle wallet
• Learning & development wallet
• Flexible time off

Let’s build it together

We envision a place where all Sifties feel secure sharing their authentic selves and diverse experiences with their teams, their customers, and their community – ultimately using this empowerment and authenticity to build trust and create a safer Internet.
