Technical Solutions Engineer

Altair is a leading provider of cellular IoT chipsets and solutions, enabling connected devices across industries such as automotive, industrial, healthcare, smart metering, asset tracking, and consumer electronics. Our technology powers reliable, low-power connectivity for millions of devices worldwide. At Altair, the people are the heart of our company. We're a team of engineers, builders, and problem-solvers who take ownership from day one. You'll work closely with experienced teammates, contribute to real decisions, and see your impact from concept through delivery. We maintain a flat organization where ideas flow freely between engineers and leadership, and experienced team members actively mentor newer colleagues. We are looking for a Technical Solutions Engineer to join our Technical Solutions team. You will be the technical bridge between our customers, our module partners and Altair R&D - helping customers design in our ALT1250, ALT1350 and next-generation chipsets and taking them from evaluation to mass production. Location: USA, Remote (with periodic travel to customer sites) Work authorization: Candidates must be legally authorized to work in the United States. Visa sponsorship is not available for this position. Responsibilities: Act as the main technical point of contact for assigned customers and module partners, from first evaluation through design-in, certification and mass production. Support customers with hardware and software integration: reference designs, RF guidance, power optimization (PSM, eDRX), GNSS and Wi-Fi positioning, and host MCU integration. Debug field and lab issues end to end - analyze modem logs, AT command flows, protocol traces and RF measurements, reproduce problems, and drive them to resolution with R&D. Help customers bring up and port applications on the embedded MCU (C/C++, RTOS, drivers, FOTA, CoAP/MQTT/LwM2M stacks). Support carrier certification and interoperability activities (PTCRB, GCF, operator acceptance) together with partners and labs. Run technical presentations, workshops and demos for customers, and contribute to RFQs, feature comparisons and competitive analysis. Capture customer requirements and feature requests and translate them into clear inputs for Product and R&D. Write application notes, FAQs and internal knowledge-base content. Travel periodically to customer and partner sites (mainly within North America, with occasional travel outside North America). Requirements: B.Sc. in Electrical Engineering, Computer Engineering or a related field. 3+ years in a technical customer-facing role (field application engineering, solutions engineering or technical account management), plus 5+ additional years in technical roles such as system engineering, embedded development or RF engineering. Solid understanding of 3GPP cellular standards across 4G and 5G (LTE, LTE-M/NB-IoT, 5G NR and RedCap). Working knowledge of IP networking and IoT protocols: TCP/IP, UDP, CoAP, MQTT and LwM2M, plus cloud connectivity with AWS (e.g., AWS IoT Core). Practical RF knowledge: link budget, sensitivity and TRP/TIS concepts, and comfort working with spectrum analyzers and call boxes. Hands-on embedded programming in C/C++ on MCUs, including RTOS, peripherals (UART, SPI, I2C) and low-level debugging. Experience reading and analyzing modem logs, protocol traces and AT command sessions. Proven experience working directly with Tier 1 customers, with strong customer-facing communication skills - able to explain complex technical issues clearly to engineers and managers alike. Familiarity with AI tools for coding and debugging (e.g., AI coding assistants for writing code, analyzing logs and troubleshooting). Self-driven and organized, able to manage several customer projects in parallel while working remotely. Nice to have Experience at a cellular IoT chipset or module company. Familiarity with FOTA and device management. Background in carrier certification (PTCRB, GCF, AT&T / Verizon / T-Mobile acceptance). Knowledge of GNSS, low-power design and battery-life optimization for trackers. Exposure to 5G RedCap / eRedCap, NTN or device security #J-18808-Ljbffr Altair Semiconductor
