Highly Valued

• Experience in enterprise SaaS, mission‑critical systems, compliance‑sensitive domains, or workflow‑heavy platforms.
• Experience with evidence management, records systems, chain‑of‑custody concepts, or highly trusted data systems.
• Experience supporting hybrid, on‑prem, or cloud‑connected product architectures.
• Familiarity with languages and platforms commonly used in modern backend environments such as Java, Go, C#, Python, or similar.
