Description

Description

Appcharge is a leading direct-to-consumer platform for app publishers.

We help publishers sell digital goods directly to their users - bypassing traditional app store commissions and owning the full payment and commerce experience.

The result: higher margins, better flexibility, and a more direct relationship with end users. Backed by $89M from leading investors and operators, we’ve grown 14x in the past year and now process over a billion dollars annually. We’re building the infrastructure that lets modern app businesses take back control of monetization – at scale.

As a Security Engineer, you will play a key role in securing and evolving Appcharge’s systems. You’ll work on high-scale, cloud-native services that power critical business flows, with end-to-end secure ownership — from design and architecture to production, monitoring, and continuous improvement.

You’ll collaborate closely with engineers, product managers, and other stakeholders, and serve as a technical leader within the R&D, DevOps and IT teams.

Responsibilities

• Lead and enforce secure development (S-SDLC) across R&D, establishing security policies, compliance standards, reusable code, and coding checklists.
• Conduct threat analysis, risk assessments, and secure design reviews across diverse technologies and complex product scenarios.
• Act as the primary security focal point for R&D stakeholders to track security posture, address challenges, and define risk mitigation plans.
• Build the training roadmap, deliver best-practice guidance, and raise overall security awareness across organizational teams.

Requirements

• 4+ years of security architecture experience, including threat modeling, end-to-end architectural considerations, and secure design reviews for complex, production-grade systems.
• Deep expertise in building, implementing, and enforcing security policies, industry standards, and S-SDLC processes.
• Strong background in Cloud Security Architecture (AWS/GCP etc.), modern software design, and distributed systems.
• Exceptional problem-solving and cross-functional communication skills, combined with a proactive, hands-on startup mindset suited for a fast-paced environment.
