Senior Software Engineer
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we should map content accordingly.
We have:
- About This Role: description of role, responsibilities? It includes: "As a Senior Software Engineer on the Ecosystem Services Team, you’ll build and own back-end systems and the integrations that keep our services running, help maintain and evolve the cloud infrastructure the application runs on, and play an active role in keeping the service reliable and healthy in production. You'll do this while collaborating closely with frontend engineers, product managers, CloudEng, and UX and design partners to deliver reliable features. We are looking for engineers who treat the systems they build as their own: people who are comfortable owning a service end to end, from writing the code to verifying it works as intended in production and monitoring its health. We are hiring for multiple Ecosystem Services Team back-end teams - each solving their own unique challenges to make the web better for everyone. More details about all hiring teams will be shared in the interviews."
- About Ecosystem Services: description of team and services.
We could combine these into About the role section.
Responsibilities: from "What You’ll Do" bullet list.
Requirements/Qualifications/Skills: from "What You’ll Bring". Could separate into Requirements (experience), Qualifications (education? none), Skills (technologies). But we can just put them under Requirements or Skills. The instruction: prefer few substantive sections over many thin ones. So maybe combine Requirements and Skills into one section? But we need to follow headings list; we can include only those with content. Could include Requirements (experience) and Skills (technologies) as separate if they have content. Let's see.
What You’ll Bring includes:
- 4+ years of experience in software development with a strong focus on backend technologies
- Strong professional experience with Python, TypeScript/Node.js, or Rust building back-end services and confidence leading back-end engineering projects.
- Proficiency with PostgreSQL and SQL query optimization, including relational schema design and migrations with a query builder such as Knex
- Hands-on DevOps experience on Google Cloud Platform (GCP), with Docker-based build and deploy pipelines. You are comfortable deploying, operating, and troubleshooting services in the cloud rather than handing that responsibility to someone else
- Hands-on experience with observability and monitoring tooling such as Sentry and Grafana
- A pragmatic commitment to shipping quality work...
- Strong engineering judgment...
- A genuine ownership mindset...
- Experience mentoring junior engineers and driving technical excellence...
- Bonus Points For Experience With Performance / load testing
- Experience with IaC tools such as Terraform and Kubernetes
- Open-source contributions or personal engineering projects
- Django experience
Thus we can have Requirements (maybe the core requirements) and Skills (bonus/technical). But we could also have Qualifications (maybe none). Better to have Requirements (the mandatory) and Skills (bonus). However the instruction: "Prefer a few substantive sections over many thin ones." So maybe combine into one "Requirements" section that includes both mandatory and bonus? But then we lose distinction. Could still be okay. But we need to follow the headings list; we can include Requirements and Skills if we have content. Let's decide to include Requirements (mandatory) and Skills (bonus/technical). That's two sections.
Benefits: from "What You’ll Get". That's substantive.
Pay: from hiring ranges.
Schedule: none.
Thus sections: About the role, Responsibilities, Requirements, Skills, Benefits, Pay.
We need to output only HTML fragment, no markdown fences.
We need to use for each section heading. Use - for any list of duties/requirements/benefits. Use
for prose.
We must preserve all substantive information; do not invent or summarize away detail. Must not repeat job title. Must not include Job ID etc. Must remove boilerplate/legal/EEO etc. Also remove duplicated lines.
We need to ensure we include all substantive info from the posting, but we can condense into lists where appropriate.
Let's extract content.
About the role: combine About This Role and About Ecosystem Services.

- Ecosystem Services builds and operates the back-end platforms that power Mozilla products and services, with a focus on privacy, security, and delivering critical functionality to Firefox and millions of users worldwide. Our portfolio spans a diverse set of platforms and services. Representative examples include Privacy Services, which provides the APIs and infrastructure behind Mozilla VPN, Relay (email and phone aliasing), and Monitor (data breach detection and remediation); AutoPush, Mozilla's Web Push platform for securely delivering notifications and real-time updates to Firefox clients; and Remote Settings, Mozilla's platform for delivering configuration updates to Firefox outside the regular release cycle. Together with many other backend platforms across the organization, these services help deliver secure, reliable experiences to Mozilla users every day. Our teams own services end-to-end from designing and building distributed systems, to operating them in production, improving reliability, and evolving the cloud infrastructure they run on. We work closely with product, frontend engineering, Cloud Engineering, UX, and design partners to build resilient systems that make the web better for everyone. We're hiring backend engineers across multiple Ecosystem Services teams, each tackling different technical challenges while sharing a culture of ownership, collaboration, and operational excellence. More details about the specific teams and domains will be shared during the interview process.
We can combine into a couple paragraphs.
Responsibilities: from "What You’ll Do". List items:
- Lead backend development, building and maintaining server-side logic
- Take real ownership of the services you work on: deploy them, operate them, and keep them healthy in production rather than handing them off
- Work closely with our CloudEng Team to maintain and improve production environments, including monitoring and alerting with tools such as OpenTelemetry, Sentry, Prometheus, and Grafana
- Participate in an on-call / off-hours support rotation, triaging and resolving production issues, partnering with CloudEng and support teams to investigate incidents, address bug reports, and keep the application running reliably
- Periodically rotate into a support role, handling releases, dependency updates, and incoming work requests from customer support and other stakeholders
- Thoughtfully apply AI-assisted development tools to move faster and raise quality, while maintaining good judgment about where they fit and where they don't
- Partner with and support stakeholders (e.g. front-end, platform), ensuring backend systems, APIs, and data contracts meet their needs
- Partner with frontend and cross-functional teams to align on project goals, contribute to API design, and ensure backend systems, APIs, and data contracts meet their needs
- Participate in code reviews to maintain high standards of code quality and system reliability
- Participate in security and privacy reviews, ensuring all data protection measures meet compliance standards
