The Role

We’re looking for an exceptional Senior Backend Engineer to take ownership of production backend systems and help integrate and evolve new products within Mode. This is a hands-on role for someone who is comfortable entering unfamiliar codebases, quickly understanding complex systems, identifying risks, and turning them into reliable, maintainable production systems.

You will collaborate closely with product, design, data, and frontend engineering to deliver features through rapid development cycles and deployment. We are an AI-native company, and you’ll be expected to use modern AI coding and agentic tools as a force multiplier in your everyday engineering work.

Quickly learn and apply new technologies as needed
Work with high-volume data systems and event-driven architectures
Improve observability, monitoring, logging, testing, and alerting
Identify performance bottlenecks and implement optimization strategies
Build distributed systems with multiple services, queues, external APIs, and asynchronous data flows
Ensure uptime, stability, and production resilience
Build resilient integrations with third-party services
Work in 2-week sprints with CI/CD and strong code quality practices
Partner with product, data, and frontend to ship features
Participate in system design and architecture reviews

What You Bring

Experience taking ownership of an existing production system or codebase
Ability to quickly understand unfamiliar architecture, code, dependencies, and operational workflows
Strong debugging and problem-solving skills in systems you did not originally design
Comfortable working with incomplete documentation and ambiguity
Ability to identify technical risks and prioritize what needs to be fixed versus what can be left alone
Work across teams and systems to integrate backend services, data, APIs, and operational workflows
Understand dependencies between products and identify opportunities to simplify or standardize where it makes sense
Help evolve inherited systems while maintaining product velocity and customer reliability
Strong production ownership mindset

Take ownership of existing backend services and become a reliable technical owner
Investigate production issues across application, infrastructure, data, and third-party dependencies
Identify and address reliability, security, performance, and maintainability risks
Improve observability, testing, deployment, and operational practices
Make pragmatic decisions about technical debt and modernization
Establish enough documentation and operational knowledge that systems are no longer dependent on a small number of individuals

Strong production experience with Ruby on Rails and the ability to work effectively in an existing Rails codebase
Hands-on production experience with PostgreSQL, including schema design, indexing strategies, query optimization, and performance tuning
Strong expertise with Sidekiq for background job processing, including scheduling, throttling, batching, and reliability patterns
Solid background in API design, RESTful principles, versioning, and serialization
Proven track record of integrating with third-party APIs and external services
Experience designing, building, and scaling distributed systems in production
Strong skills in testing, CI/CD pipelines, logging/monitoring, debugging, and performance optimization
Ability to work in a fast-moving remote startup environment

Preferred:

Experience building and supporting backends for mobile apps
Experience creating internal tools or admin panels with ActiveAdmin
Hands-on work with Shoryuken for SQS message processing
Experience integrating payment processors like Stripe
