• Senior Flutter & .NET Software Developer

Job Overview:

Riseup Labs is looking for a Senior Software Developer, Mobile (Flutter and .NET). We are hiring for our client, a Canadian SaaS company in the landing page, conversion optimization and CRM space, currently going through an AI-first product transformation. This is a backfill role on the client’s CRM mobile engineering team, reporting to engineering leadership. The candidate will own work on the company’s mobile apps, which serve hundreds of thousands of active users on iOS and Android. The apps are built in Flutter, and about half of the role is backend work in .NET.

Work split: About 50% Flutter and 50% .NET backend (ASP.NET MVC on .NET Framework 4.8).

Job Responsibilities:

• Build, ship and maintain Flutter features for iOS and Android, from requirements through release.
• Build and change backend APIs and services in ASP.NET MVC on .NET Framework 4.8.
• Diagnose and fix mobile performance, memory, battery, connectivity and device compatibility problems.
• Handle data synchronization, push notifications, secure storage and secure API communication.
• Use CI/CD pipelines and monitoring tools to ship safely and respond to production issues.
• Support onboarding and knowledge sharing for newer developers through code reviews and pairing (informal, with no people management).
• Communicate progress, trade-offs and risks clearly to non-technical stakeholders.
• Join the team’s two-week Release Developer and Production On-Call rotations once production access is approved. Until then, work on features, code reviews and business-hours support.

About the rotations

• Release Developer: coordinates release builds, makes sure changes merge on time, and deploys to production.
• Production On-Call: first responder to PagerDuty and Slack alerts, 24/7, with a 15-minute response before the alert escalates to engineering leadership. Playbooks exist for each alert type.
• Frequency: about one two-week rotation every four weeks. A developer is never on both rotations at the same time.

Typical alert volume:

• About 2-3 pages a week across the team, mostly early morning (6-9 AM PT) or evening.
• True overnight pages (10 PM - 7 AM PT) average about one a week.
• About 60% clear on their own or need only a quick check.
• Roughly once every two weeks, an incident needs hands-on action, such as restarting services, taking a memory dump, or working with infrastructure.
• Real incidents usually last 15 minutes to a couple of hours.
• Phased start: a shadowing period before taking on rotations is expected.
• App Store and Google Play submissions, staged rollouts and release notes are handled by the client.

Required Skills & Qualifications:

• 4+ years of professional software development, with production apps released to the App Store and Google Play.
• 3+ years of Flutter and Dart on production apps.
• 3+ years of C# and ASP.NET MVC, with working knowledge of .NET Framework 4.8.
• Experience with mobile performance tools, secure storage and secure API communication.
• Experience with CI/CD pipelines and production monitoring and alerting.
• Experience carrying a 24/7 on-call rotation and responding to production incidents.
• Experience mentoring or leading less experienced developers.
• Ability to work a full Pacific Time business day.

Nice to have:

• AWS (Lambda, S3, DynamoDB, Kinesis)
• TeamCity, Octopus, PagerDuty and Datadog
• Experience on a legacy .NET Framework codebase, or migrating to modern .NET
• Large user bases, staged rollouts and feature flags
• CRM or B2B SaaS product experience
• Owns a feature from the first ticket to production monitoring.
• Stays calm when a release or an alert goes wrong at an inconvenient hour.
• Pushes back on unclear requirements and unrealistic estimates.
• Tells the team early when something will take longer than hoped.

Workplace:
