API Integrations Engineer vs Embedded Systems IOT Engineer: the US Salary & Career Benchmarks

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 $115K, whereas a API Integrations Engineer brings in roughly $108K (a gap of $7K at the median).

This difference narrows and widens depending on tech stack and location. Roles based in major hubs like Atlanta typically pay a 15–25% premium to offset local cost-of-living pressures. Fully remote positions across the US tend to compress toward the national median. 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, API Integrations Engineer and Embedded Systems IOT Engineer have fundamentally different daily workflows.

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

Embedded Systems IOT Engineer focuses on designing and building the embedded firmware and IoT connectivity layer for smart-city and industrial systems. Their time is spent 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.

Essentially, API Integrations Engineer tends to build and maintain the point-to-point and platform integrations that connect an organisation's products, while Embedded Systems IOT Engineer designing and building the embedded firmware and IoT connectivity layer for smart-city and industrial systems.

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

Moving from API Integrations Engineer to Embedded Systems IOT Engineer: Electrical or computer engineers with C/C++ firmware experience and hands-on hardware debugging skills transition in fastest, especially those with RTOS exposure.

Moving from Embedded Systems IOT Engineer to API Integrations Engineer:

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 strong demand, but with different drivers.

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

Embedded Systems IOT Engineer shows sharper hiring velocity in specialist contexts, particularly as the 2026 AI and cloud transformation push continues across both markets.

Following widespread Return-to-Office mandates across the US in 2026, workspace flexibility significantly impacts total compensation values.

API Integrations Engineer roles score 60% on our remote-friendliness index (High). This is because 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. Where in-office attendance is required, it is typically driven by 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.

Embedded Systems IOT Engineer roles score 25% (Low). 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 is the primary driver of flexibility. When office days are required, it is usually for 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.
