Senior Software Engineer, Backend
to join our growing Integrations team. This role is critical to building and scaling the systems that power Cognitiv’s partnerships with other platforms and clients. You’ll work across our suite of products, enhancing backend services, developing APIs, and supporting new integrations that directly drive revenue and customer impact. You’ll be joining a highly collaborative environment — working closely with Business Development, Customer Success, and Product teams to deliver seamless integrations that help our clients achieve their advertising goals.
Location:
Hybrid MTW in Bellevue Office.
What You’ll Do
Build and maintain scalable, reliable backend systems that power integrations across multiple products.
Collaborate with cross-functional teams (Business Development, Product, Customer Success) to define requirements and deliver solutions that enable new business opportunities.
Dive deep into a large, multi-product codebase — debugging, optimizing, and improving backend performance.
Write clean, maintainable, and well-tested code with a strong focus on operational excellence.
Ensure backend systems are well-documented, observable, and resilient in production.
Identify opportunities to automate processes, improve performance, and enhance system reliability.
Tech Stack
Languages: C#, .NET Core
Infrastructure: AWS, Docker,
Data: Datadog
Tools: Rider, DataGrip
Who You Are
You’re an experienced backend engineer who thrives in ambiguous, fast-paced environments.
You love exploring and improving complex systems — not afraid to jump into unfamiliar codebases.
You communicate clearly and collaborate effectively across technical and non-technical teams.
You care about code quality, testing, and operational excellence just as much as you care about shipping features.
You take ownership of your work and follow projects through from idea to production.
Bonus Points If You Have
Experience working on integrations or partner-facing systems.
Background in AdTech, MarTech, or Data Engineering.
Familiarity with CI/CD pipelines and monitoring tools (Grafana, Datadog, etc.).
Exposure to distributed systems, large-scale APIs, or event-driven architectures.
Salary $160,000 - $210,000 USD Base Salary + Equity
What We Offer Compensation is based on experience, skills, and other factors. Base salary is just one part of your total rewards at Cognitiv—you’ll also receive equity and a comprehensive benefits package.

12 weeks paid parental leave
Unlimited PTO + Work‑From‑Anywhere August
Career development with clear advancement paths
Equity for all employees
Hybrid work model & daily team lunch
Health & wellness stipend + cell phone reimbursement
401(k) with employer match
Parking (CA & WA offices) & pre-tax commuter benefits
Employee Assistance Program
Comprehensive onboarding (Cognitiv University)
…and more!
