What are the responsibilities and job description for the POS Engineer position at Estuate, Inc.?
POS Engineer
Boston, MA
Contract: 12 Months
A senior individual contributor with deep POS and QSR experience who can combine edge computing, OS strategy, and capacity planning to deliver practical, future ready POS architecture recommendations—without forcing unnecessary hardware refreshes.
- Evaluate current POS hardware and deployment models
- Evaluate edge based architectures that:
- Reduce dependency on POS terminal OS EOS
- Allow POS logic to move off the register where appropriate
- Support 100% seamless offline operation and high volume store environments
- Help define where workloads should run:
- POS endpoint vs store edge vs cloud
- Assess hardware and OS choices against future growth, including AI driven workloads
- Deliver clear architecture recommendations, diagrams, and tradeoff analysis with the team
Required Experience (Must Have)
POS & QSR Experience
- Hands on experience with large enterprise POS systems in QSR or high volume retail
- Strong understanding of:
- Transactions
- Payments
- Peripherals
- Offline / degraded network behavior
- Experience designing around existing POS platforms, not replacing them
Edge Computing & Architecture
- Real experience designing or operating edge computing in distributed environments
- Comfortable with store level compute models that work even when the network is down
- Experience supporting mixed fleets (legacy hardware new stores)
POS Hardware
- Experience with enterprise POS hardware such as:
- NCR
- Oracle MICROS
- HP (or similar vendors)
- Understands hardware lifecycle realities (long refresh cycles, mixed environments)
OS & Imaging (Hands On)
- OS imaging and lifecycle management experience
- Windows LTSC in POS environments (including tradeoffs)
- Linux for edge or backend workloads (practical use, not ideological)
Future Ready & Capacity Planning (Critical)
- Understands how emerging technologies (e.g., AI, real time analytics, automation) impact store compute needs
- Experience with capacity planning and technology decisions looking 3–5 years out
- Able to design architectures where software growth does not immediately force hardware upgrades
- We are not looking for someone to build AI models—
- we are looking for someone who understands what AI and future software demand from infrastructure.
Nice to Have
- Headless or API first POS / commerce architectures
- Containerized workloads at the edge
- PCI boundary and payment isolation experience
- Experience producing architecture documents for both technical teams and executives
