Senior Software Engineer

MNTN is a company that prioritizes its people and has been recognized as one of Ad Age’s Best Places To Work in 2026. They are seeking a Senior Backend Engineer to join their Integrations team, responsible for evolving the Integrations platform and managing data flows to maximize business impact.

Responsibilities:

• Work closely with the rest of the team to evolve the Integrations platform to handle trillions of tuples across hundreds of different integrations
• Own the design, implementation, testing, monitoring, and optimization of integration connectors
• Work closely with both technical and non-technical cross-team stakeholders to get our data streams where they’ll have the biggest impact on the entire business
• Find creative, scalable, and durable solutions to tough data synchronization challenges spanning across our systems and our partners'
• Join our on-call and other rotations that share the load equally among the team. It takes a village
• Bring energy and creativity to our use of AI, our knowledge shares, retros, and other regular team growth activities

Requirements:

• 5+ years of experience as a full-time backend engineer working on a SaaS product with a large data component. I.e. not just building APIs for UIs
• Experience with distributed microservice architectures: reliable service design for autoscaling (containers appear and disappear all the time), RESTful service-to-service communication (even if its an RPC protocol)
• Experience with at least one compiled language. Golang is preferred, but Rust, Kotlin, Java, C++ are welcome
• Experience with at least one messaging system (Kafka, SQS, PubSub, RabbitMQ, etc) at scale (message volumes of 1K/s+)
• A foundation in CS fundamentals: data types, algorithms, CPU/memory management, networking, how the internet works
• Experience with observability systems for microservice architectures: structured logging, tracing, custom metrics
• Are a design-driven professional. You form a plan of attack and articulate it on paper to make sure its sound. You don't document for-its-own-sake, but you don't just start shoveling code and pray for the best either
• Are comfortable with Postgres-flavor databases. You're not necessarily a SQL expert, but you know about relational database concerns (indices, foreign/unique constraints, why you should never use stored procedures)
• Are more comfortable on the command-line than in UIs
• Can communicate clearly and concisely with both technical and non-technical peers
• An idealistic but practical mindset: aim for the stars, but focus on what will make the biggest difference right now
