Flexible Models of Collaboration
Every engineering project has different requirements. Some organizations need a specialist with a specific technical skill set, while others need a complete team to develop a product or subsystem.
Sigma Connectivity offers several ways to collaborate, depending on the required expertise, project scope, and responsibilities.
Individual Specialists
An experienced engineer joins an existing client team to address a specific skills gap or technical challenge.
This model is suitable when a project requires specialized knowledge in areas such as Embedded Linux, C++, AOSP, DSP, wireless connectivity, or Edge AI.
Team Augmentation
One or more engineers join the client's existing R&D team and work alongside its specialists.
The client maintains ownership of the product roadmap and project priorities while gaining access to additional engineering expertise.
Dedicated Engineering Teams
A multidisciplinary team works on a defined product, subsystem, or development stream.
Depending on requirements, the team can combine embedded software, AI, connectivity, mobile development, hardware integration, and other relevant disciplines.
Project-Based Development
Sigma takes on an agreed engineering scope, such as a proof of concept, prototype, software component, integration task, or optimization project.
Deliverables, responsibilities, and acceptance criteria are defined according to the project's objectives.
End-to-End Product Development
For projects requiring broader support, multiple engineering disciplines can contribute throughout the product lifecycle — from technical exploration and architecture to implementation, integration, testing, and production preparation.
The appropriate model depends on the client's internal capabilities, project objectives, and the level of responsibility assigned to Sigma.
Starting a Project in as Little as Two Weeks
Access to the right expertise can make a significant difference when a project faces a technical challenge or needs additional engineering capacity.
Our approach focuses on understanding the required competencies and matching them with specialists whose experience is relevant to the work.
Depending on specialist availability, project scope, and onboarding requirements, collaboration can begin in as little as two weeks.
This provides a way to introduce specific technical capabilities into an existing team or start a defined engineering activity without a lengthy recruitment process.
Bringing Specialized Engineering Knowledge Together
Modern technology products increasingly depend on close collaboration between engineering disciplines. Low-level software must work reliably with hardware, connectivity must integrate with embedded platforms, and AI performance depends on both algorithms and the underlying computing architecture.
At Sigma Connectivity, we have specialists across these areas, combining deep technical knowledge with experience in product development.
Whether a project requires expertise in firmware, Embedded Linux, Edge AI, computer vision, Android, wireless connectivity, audio processing, or broader system integration, our engineers can contribute at the level where their knowledge is needed.
Our strength lies in the depth of our engineering expertise and our ability to bring the right specialists together to solve complex technical challenges.
