Senior/Staff Backend Engineer

Remote (U.S.-based; Eastern Time Zone preferred)

Why this role matters
Join a fast-growing, product-focused company as a senior contributor helping to build the infrastructure behind large-scale, high-performance data systems. You’ll work on complex backend platforms that process billions of rows of data, surface meaningful insights, and power decision-making for customers.

This is a high-impact, high-ownership role where you'll contribute to architecture, implementation, and strategy on a modern backend stack with lots of room to innovate.

What you'll do

• Design and deliver scalable backend services that process and model large datasets efficiently and reliably

• Build extensible internal platforms and tooling (e.g. APIs, data services, internal developer tools)

• Own full systems end-to-end, from concept to architecture to deployment

• Lead key technical initiatives, improving performance, accuracy, and cost-efficiency

• Occasionally contribute to frontend layers to ship full product features

• Work cross-functionally with product, sales, and customer teams to understand needs and deliver technical solutions

• Apply statistical thinking and experimentation to platform decisions (experience with ML or modeling is a plus)

Sample projects

• Optimization engines that act on real-time and historical performance signals

• Data pipelines and deployment infrastructure for statistical and ML models

• Scalable systems for querying and enriching data graphs across billions of rows

• Integration of multiple data sources into unified, production-grade models

• AI-driven internal tooling that simplifies workflows and delivers actionable insights

Tech stack and environment

• Languages: Python, TypeScript/Node.js, Go, React (language choice is flexible based on experience)

• Cloud: AWS (extensive usage; prior experience helpful but not required)

• Databases: ClickHouse, PostgreSQL, Redis, DynamoDB

• Architecture: Data pipelines, event-driven systems, internal platforms and developer tooling

What we’re looking for

• 5+ years of professional experience writing production backend code

• Hands-on experience with pipelines, ETL/ELT, event-based systems, and schema design

• Proven ability to build internal tools and services that are extended by other teams

• Experience with system design for scale, performance, reliability, and cost optimization

• Clear and thoughtful communication skills in both async and real-time settings

• Self-directed and comfortable with ambiguity; thrives on autonomy and ownership

• Bonus: exposure to statistical modeling, ML pipelines, or AWS services

Why this team

• Your work will directly shape how customers interpret and act on high-volume data

• You’ll be part of a lean team with strong ownership and a bias for action

• You’ll contribute to modern, outcome-driven engineering with measurable impact

• You’ll have the space to prototype, test, and scale ideas into full systems
