How to Apply for Senior Software Engineer
at MissionWired
🏢 About MissionWired
MissionWired is a mission-driven company that has raised over $4.5 billion for nonprofits and progressive campaigns, combining technology with social impact. Working here means your engineering directly supports causes like climate action, social justice, and public health.
About This Role
As a Senior Software Engineer, you'll own and evolve the production data and ML platform, ensuring reliability and scalability. Your work will directly power fundraising and advocacy efforts for nonprofits by building robust pipelines and deploying ML models at scale.
💡 A Day in the Life
You'll start by reviewing pipeline health dashboards and any alerts from overnight runs. Mornings often involve collaborating with data scientists to design new ML features, while afternoons are for coding, code reviews, and optimizing Databricks jobs. You'll also participate in on-call rotations and team standups to ensure platform reliability.
🚀 Application Tools
🎯 Who MissionWired Is Looking For
- Experienced software engineer with a strong track record of building production data pipelines (5+ years preferred).
- Deep expertise in Python for production systems, including writing high-quality, testable code.
- Hands-on experience with Databricks or Spark pipelines, and integrating ML models into production (batch inference, model serving).
- Proficient in SQL and cloud platforms (GCP, AWS, or Azure), with a focus on scalable data infrastructure.
📝 Tips for Applying to MissionWired
Highlight specific examples of production Databricks/Spark pipelines you've built and maintained, including scale and impact.
Showcase your experience integrating ML models into production workflows, not just building models in notebooks.
Emphasize any work with fundraising, political campaigns, or nonprofit tech—MissionWired values domain alignment.
Tailor your resume to emphasize reliability, scalability, and operational excellence (e.g., monitoring, alerting, SLAs).
Include a brief note in your cover letter about why you're passionate about supporting progressive causes and nonprofits.
✉️ What to Emphasize in Your Cover Letter
["Your passion for using technology to drive social impact and align with MissionWired's mission.", 'Concrete examples of owning and improving production data/ML platforms, especially with Databricks/Spark.', 'Your ability to partner with data scientists to productionize ML models and solve real-world problems.', 'Experience with cloud infrastructure and building reliable, scalable pipelines that serve business needs.']
Generate Cover Letter →🔍 Research Before Applying
