Role Overview

We’re looking for a Staff Software Engineer to serve as a technical pillar across our engineering teams. This role is ideal for a highly experienced backend engineer who thrives on solving hard problems, mentoring others, and guiding architecture across multiple domains. You’ll be a multiplier, operating independently, shaping technical direction, and partnering with engineers 
and product teams to raise the bar across the organization. 

You’ll work across squads to improve system performance, reliability, and scalability, while owning high-impact projects that support our Advertising platform. Whether it’s unblocking performance bottlenecks, leading design for new backend services, or reducing tech debt, your contributions will have a far-reaching impact. 

This is a high-impact role where you will not only write mission-critical code but also provide the AI-driven roadmap to help our team automate optimizations and anomaly detection within our data pipelines. 

Core Responsibilities 

  • Own and lead design for major backend systems across Ads, focusing on performance, scalability, and reliability. 
  • Serve as the subject matter expert for Python & Django. You will optimize application performance, focusing on concurrency, memory management, and efficient integration with our data layer. 
  • Architect and optimize large scale data workflows for Ads. You will be expected to tune complex queries in Hive, Flink, or Trino to reduce latency and cost while maintaining data integrity. 
  • Actively profile our stack to identify bottlenecks. You should be comfortable moving between high-level architectural planning and low-level query optimization. 
  • Guide the engineering team in leveraging AI and Machine Learning for predictive analytics, automated QA of data streams, and enhancing our internal decision-making engines.  
  • Collaborate with multiple teams to address cross team concerns (e.g., shared libraries, infra patterns, tech debt, security) 
  • Tackle escalated production issues / incidents by providing quick remediations 
  • Raise the engineering bar through elite code review, technical RFCs and hands on guidance for senior and mid-level engineers. 
  • Work with EMs and PMs to shape technical roadmap and support long-term platform health. 
     

Technical Requirements 

  • 10+ years in backend engineering with a proven track record of scaling systems in Ad-Tech, Fintech or High-Scale SaaS. 
  • Deep expertise in building high concurrency, asynchronous services. You know how to scale Django beyond standard patterns. 
  • Strong experience with distributed systems (e.g. Flink, Spark, Hive or SingleStore). You are an expert at optimizing distributed joins and partitioned datasets. 
  • Advanced SQL skills; you can dissect an execution plan and optimize complex analytical queries for both performance and cloud cost. 
  • Experience managing “Sync vs Async” data flows and ensuring consistency across disparate data stores 
  • Experience with containerization technologies such as Docker and Kubernetes. 
  • Familiarity with CI/CD pipelines and modern DevOps practices. 
  • Strong communication skills with the ability to explain complex technical concepts to non-technical stakeholders is a must. 
  • Proven leadership experience, including mentoring engineers and leading technical initiatives. 
     

Ideal Candidate 

  • The Pragmatic Architect: You understand the trade-offs between “perfect” code and “performant” code in a high throughput environment. 
  • The Data Integrity Advocate: You care deeply about how data is captured at the source just as much as how it is processed at scale. 
  • The Force Multiplier: You don’t just solve problems; you build systems and processes that prevent them from recurring. 
  • The Mentor: You thrive on helping others grow and can explain complex architectural concepts to both engineers and stakeholders. 

Our Benefits: 

Full-time employees can take advantage of health coverage, paid parental leave, generous paid time-off and holidays, quarterly self-care days off, and stock options. We’ll make sure you have the equipment and support you need to work and connect with your teams, at home or in one of our offices. 

We have a growth mindset culture that is represented in all that we do, from onboarding through to numerous learning and development initiatives including access to our LinkedIn Learning platform. Employee well-being is also top of mind for us. We host quarterly wellness education sessions to encourage self care and personal growth. From wellness days to ERG-hosted events, we celebrate and energize all 6sense employees and their backgrounds.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
