Skills required to become an IoT Engineer 

To become an IoT Developer, you must have the following skills:

• You should have hands-on experience in coding in multiple programming languages, including Embedded-C, Embedded C++, and Python. 
• It would help if you had an in-depth understanding of Linux OS and its process management, device management, and connectivity features. 
• You should be well-versed in embedded software architecture – prior experience in working with UML use-case diagram, class-diagram, and sequence diagram to accurately depict system architecture is highly valued.
• You should possess in-depth technical knowledge in working with 32-bit ARM cortex M3/M4 controllers.
• You should have prior experience in working with wireless stacks like Zigbee or Thread or BLE-Mesh.
• You should have expert knowledge and be proficient in writing business logic on embedded environments using test-driven methodology on RTOS and non-RTOS platforms.
• You should be proficient in communication protocols including I2C, SPI, 1-wire, UART, MODBUS, DALI.
• You must have excellent communication, problem-solving, and analytical thinking abilities. 

Company background and Vision

We at Neysa believe that good software is one where you don’t have to (necessarily) read the full manual. Good software is intuitive, inviting and accommodating. Most importantly, good software should make life easy. That’s easier said than done, though. Good software is definitely hard to write. For the end user to be required to do the least amount of work, the developer has to do the most. To get the most out of a computer system, the code should be as native as possible. Neysa is out to build the most intuitive network management software ever, and we hope you would write code to bring that vision to life.

Day in the life In this role...

Work with time-sensitive and streaming data for analysis, filtering and sorting, for example, the C++ STL. Create parallel processing architectures which can scale up and down on demand. Interact with external systems and handle their idiosyncrasies in a live, data-heavy, time-constrained environment. Provide a resilient and predictable platform for upper-layer applications. Come up with bespoke solutions for real-world data handling problems. Handle cryptography and communication security over untrusted channels.

Must-have skills

On day one, we'll expect you to... Have a deep understanding of object-oriented programming, socket programming and memory management techniques. Have experience with multi-threaded and multi-core programming and its associated concurrency, locking and synchronization techniques. Be aware of interprocess communications (IPC/gRPC) and message queueing. Be comfortable with mathematical functions and the associated libraries in system programming. You also should be unafraid to use math to optimize your code. Understand synchronous and asynchronous communication, and when to use what. Be comfortable in handling low-level byte-handling operations.

What separates the best from the rest

You will need to have... The initiative to work on your own, at your own pace, but on a schedule. The courage to iterate, re-iterate and the re-re-iterate till you get it right. And then defend your design philosophy. Think through all the possible applications of your work, and then make sure it performs awesome in every one of them. Making the right algorithm choices based on design requirements. Write good, commented and (hopefully) error-free code. Logic failures are acceptable, but poor error handling is not.

What you can expect

The best equipment which complements your talents. The best tools in the business for you to bring your creations to life. A great environment. Flexible work hours, and flexible work locations. You will need to be in the office though. The opportunity to make your mark and shape the future. And have fun…

The Technical Skill Tree

Things you must know…

C, C++, Java, system programming, stream programming, socket programming, Linux Internals, Hooks and System Call and Kernel APIs. Locking and synchronizing techniques like mutexes, atomics, deadlocks and races and ways to avoid them. “Safe” programming, exception handling. String input/output and manipulation, data structure(hash tables, graphs, stacks, queues, trees, binary trees) and operations on them. System memory management, instruction reordering and memory order. A “code-based” understanding of the TCP /IP stack and other networking protocols.

Great if you know....

Garbage collection in C++, thread-safe and type-safe programming, hierarchal exceptional handling. Specialised algorithms for data collection, analysis and presentation. Understanding of the REST, protobuf, XML, JSON and other data interchange formats. Understanding of cryptographic libraries, key management concepts, and symmetric and asymmetric encryption. STL containers, API service creation, “daemons”, operating system services, microservices,

We'll help you out on ...

Web servers, system administration, website management, code management systems, and code debugging systems. CI/CD, Automation frameworks. Version management tools.
