Senior Mobile Engineering Manager (iOS & Android SDK)

You will be the clear, trusted owner for all things mobile at Opensignal, leading our iOS and Android SDK teams to deliver high-quality software that powers critical data products. You will align external business needs with engineering execution, ensure predictable releases, and protect data continuity and quality across first-party and third-party integrations.

Our products rely on our ability to measure network performance accurately and consistently from our mobile apps and SDKs. Evolving our platform in step with business requirements and operating system changes is a critical success factor for this role.

You will also help the team adopt AI in a pragmatic, safe, and outcomes-focused way, improving engineering velocity without compromising quality, privacy, or data integrity.

Your impact will be measured by reliable on-time releases, stable SDK behavior in partner apps, strong stakeholder confidence, and zero major data outages or data perturbations. Early success includes smooth onboarding and delivery of new platform support (including Android 17 and upcoming iOS releases) without regression to data quality, alongside clear progress in AI-augmented engineering workflows and platform evolution that keeps pace with product needs.

Primary Responsibilities

• Lead and directly manage the mobile engineering organization (currently 3 Android and 2 iOS engineers), including delivery planning, performance, coaching, and hiring support as needed.
• Serve as the primary cross-functional point of contact for mobile engineering with business, product, and data partnership stakeholders.
• Own end-to-end mobile release lifecycle management for our SDKs and related apps, ensuring high release quality and predictable delivery.
• Drive execution across first-party integrations (Opensignal app, Meteor app, ONX Connect) and third-party partner integrations that run our SDK at scale.
• Establish and enforce strong data-change discipline so SDK changes do not unintentionally alter critical metrics, schemas, or downstream product behavior.
• Lead experiment rollout and validation practices (feature flags, quality checks, and post-release verification) to confirm behavior changes as expected.
• Maintain compliance and policy alignment across privacy and platform requirements, including GDPR, CCPA/CPRA, Apple App Store, and Google Play policies.
• Drive pragmatic adoption of AI-augmented workflows across coding, QA, and data analysis, with clear guardrails for safety, privacy, security, and verification.
• Stay hands-on where valuable (technical reviews, architecture decisions, and targeted implementation support), while operating primarily as a manager and delivery owner.

• Typically 8+ years of experience in mobile engineering, including meaningful leadership experience managing engineers and cross-functional delivery; equivalent depth of experience from non-linear career paths is also valued.
• Strong production experience across Android and iOS ecosystems, with deep expertise in at least one platform and demonstrated leadership capability across both.
• Strong SDK development experience (not only app development), including integration and maintenance in third-party applications.
• Strong data literacy, including SQL proficiency, ability to work with Python for analysis, and practical experience in data quality monitoring.
• Experience with experiment design and validation in software releases, especially where data integrity is business-critical.
• Strong understanding of telemetry/schema change management and the downstream impact of data contract changes.
• Solid networking fundamentals and practical experience relevant to mobile measurement use cases (for example TCP/UDP/QUIC behavior, packet flow timing, latency, and time-to-first-byte concepts).
• Demonstrated ability to communicate clearly with technical and non-technical stakeholders and translate business needs into execution plans.
• Experience operating within privacy, compliance, and platform-policy constraints for mobile SDKs.
• Proactive, curious mindset toward AI and modern engineering practices, with demonstrated judgment in adopting new tooling responsibly.

We recognize that excellent candidates may not match every listed qualification exactly. If this role aligns with your strengths and experience, we encourage you to apply.

Tools & Education

• Required: production experience with Kotlin and Swift.
• Required: experience with Git-based development workflows and CI/CD release pipelines (We use Github Actions).
• Required: experience with observability and crash tooling used in mobile environments (for example Sentry, Firebase, Crashlytics).
• Required: strong SQL proficiency.
• Preferred: Python for data analysis and validation workflows.
• Preferred: experience with feature flag rollouts, emulator/device testing strategies, and release validation frameworks.
• Preferred: experience with AI-assisted engineering tools/workflows and defining safe usage standards for teams.
• Education: degree in Computer Science, Software Engineering, or equivalent practical experience.

Location: Europe (remote-first). Preferred locations are Poland, the UK, and Spain; candidates in other European countries are also welcome, based on practical time-zone overlap and ability to travel to office locations occasionally (typically once per quarter).
