Compare cost-of-living buying power and how crowded the market is versus other major tech cities—so you can focus your search where the odds fit your goals.
Baltimore offers approximately 68% lower housing costs compared to San Francisco, with median home prices around $200K versus $1.2M+ in the Bay Area. Your firmware engineering salary stretches significantly further, enabling homeownership and higher savings rates while maintaining proximity to DC's tech corridor.
Baltimore's firmware engineering market is significantly less competitive than major tech hubs. Strong demand from defense contractors and growing IoT companies creates excellent opportunities for experienced engineers.

Its flagship MycoMEIA Aspergillus urine assay, which received FDA 510(k) clearance in August 2025 and CE approval for the EU, replaces invasive bronchoalveolar lavage procedures used to detect aspergillosis in transplant recipients, cancer patients, and immunocompromised individuals. The company is extending the same antigen-detection platform to other fungal and bacterial pathogens, including a Pseudomonas assay for cystic fibrosis patients.
