About your role

The Fairphone Software Engineering team is seeking a Software Engineer to lead the integration of software features for our partners. In this role, you will be responsible for integrating specialized third-party solutions—such as advanced accessibility tools or robust digital safety features—directly into our Android ecosystem. In this role, you won't just maintain a device; you will be the technical bridge between Fairphone and our ODMs (original design manufacturers), ensuring that partner‑specific software components are seamlessly architected, integrated, and maintained within our Android ecosystem. You will champion sustainable and long lasting software development while ensuring our partners’ unique requirements are met with high‑quality, scalable solutions.

While this is a deeply technical engineering role, project management experience is essential. You will be expected to manage complex integration timelines, navigate vendor relationships, and coordinate cross‑functional delivery, ensuring that technical milestones align with broader business objectives.

You will report to our Head of Software Engineering, who reports to our CTO.

Key Responsibilities & Objectives

Your Key Responsibilities

• Design and implement software bridges and integration layers for partner‑specific components within the Android stack.
• Provide direct technical guidance and oversight to the partners to integrate their solution both within our open‑source tree and our production codebase.
• Ensure the partner components are well integrated throughout the software development lifecycle, from bring‑up to maintenance.
• Collaborate with internal quality and testing teams to validate ODM deliverables, ensuring all partner integrated features meet Fairphone’s high performance and reliability standards.
• Triage and resolve complex integration issues across hardware and software boundaries
• Own the technical documentation for partner integration projects, ensuring clear communication with both internal stakeholders and external partners.
• Manage project timelines and coordinate cross‑functional delivery, ensuring that technical milestones for partner integrations align with business objectives and vendor delivery schedules.

Key Objectives

• Architect and deliver robust software integration solutions tailored for partner requirements.
• Serve as the primary technical point of contact for ODMs and partners to ensure alignment on software stack integration, quality standards, and delivery timelines.
• Bridge the gap between internal Fairphone & partner requirements and external ODM implementation capabilities, ensuring code integrity and long‑term maintainability. This includes leveraging and contributing to our open‑source (OSS) AOSP codebase, particularly for Proof of Concepts (PoCs).

Your Skills & Experience

• You have a degree in computer science, software engineering, computer engineering, or a similar field, or have equivalent experience in one or more of these fields.
• You have 5+ years of relevant, hands‑on experience in the Android ecosystem.
• You are an expert developer proficient in the core Android and chipset stacks, including C/C++ or Rust, Java and Kotlin. You don't just write code; you architect, test, and implement robust functional requirements.
• You have the ability to lead technical discussions and negotiate technical solutions with external partners.
• Knowledge of AI/ML integration in Android (e.g., on-device AI, NPU utilization, or relevant frameworks)
• You can support building business cases
• You are used to working with Legal teams, ensuring Software compliance
• You are software quality‑driven, used to unit and integration testing, code review tools, and continuous integration.
• You are well‑versed in open‑source development methodologies and thrive in a collaborative environment.
• You excel at resolving complex issues, performing root‑cause analysis across hardware/software boundaries, and documenting your findings clearly.
• Proven experience working directly with Original Design Manufacturers (ODMs) in a technical capacity.
• Deep understanding of partner software integration workflows and the unique challenges of customizing Android for specific partner use‑cases.
• You have a solid understanding of Enterprise Firmware Over‑the‑Air (EFOTA) solutions and the specific challenges of managing update rollouts for large B2B/Enterprise device fleets.
• You are familiar with Android Enterprise system update policies (e.g., maintenance windows, mandatory updates).
• Specific expertise in any of the various HALs within Android is a bonus, such as camera, audio, WiFi or Bluetooth.
• You are proficient with GNU/Linux operating systems.
• You are proficient in spoken and written English. Most of us don't have English as our first language, but it's the primary language we use internally, as well as with our teams and partners worldwide.
