Embedded Systems / IoT Engineer vs API Integrations Engineer: Salary & Career Benchmarks in the US

In the US, Embedded Systems / IoT Engineer roles typically command a higher median salary than API Integrations Engineer positions. According to our 2026 live benchmark data, a mid-level Embedded Systems / IoT Engineer earns a median salary of $134K, whereas a API Integrations Engineer brings in roughly $125K (a gap of $9K at the median).

Seniority, tech stack, and location all move this gap. Senior practitioners in either discipline can exceed the upper range through specialist skills. See the skills premium section below for the specific certifications and tools that push offers to the top of the range.

While both positions are vital to a modern tech organisation, Embedded Systems / IoT Engineer and API Integrations Engineer have fundamentally different daily workflows.

Embedded Systems / IoT Engineer focuses primarily on designing and building the embedded firmware and IoT connectivity layer for smart-city and industrial systems. Day-to-day work revolves around writing C/C++ firmware, integrating sensors and connectivity modules, debugging on physical hardware, and testing IoT device fleets against NEOM and Saudi Aramco field conditions.

API Integrations Engineer focuses on building and maintaining the point-to-point and platform integrations that connect an organisation's products, partners, and third-party services. Their time is spent building REST/GraphQL integrations, writing and maintaining webhooks, debugging third-party API failures, and working with product teams to scope new partner integrations.

Transitioning between these two paths is achievable but requires targeted upskilling.

Neither path requires starting from scratch. Professionals in both roles share underlying technology fluency; the gap is usually domain knowledge and specific tooling rather than core engineering fundamentals.

In the US in 2026, both roles are seeing demand, but with different drivers.

Embedded Systems / IoT Engineer demand is high, particularly in cloud and platform engineering teams across Seattle, San Francisco Bay Area, and Austin, led by employers such as HashiCorp and Datadog. API Integrations Engineer demand is high, concentrated in product engineering teams across New York, Austin, and San Francisco Bay Area, led by employers such as Stripe and Block.

Workspace flexibility significantly impacts total compensation value in the US.

Embedded Systems / IoT Engineer roles score 25% on our remote-friendliness index (Low). This is because much of the work is asynchronous and tool-driven, though many US employers, particularly larger firms with formal return-to-office mandates, still expect two to three days a week in a Seattle or San Francisco Bay Area office. Where in-office attendance is required, it is typically driven by cross-functional collaboration and stakeholder alignment sessions, which US employers headquartered in Seattle and San Francisco Bay Area increasingly formalize into a fixed hybrid schedule rather than leaving to team discretion.

API Integrations Engineer roles score 60% (High). Integration build and debugging work is largely async and tool-driven, and US employers are more willing to hire this role fully remote than the more senior API & Integration Architect track above it is the primary driver of flexibility. When office days are required, it is usually for scoping sessions with partner and product teams during a new integration's early design phase, which some US employers still prefer to run in person for the first few weeks of a project.
