Company Description

Devexperts works with respected financial institutions, delivering products and tailor-made solutions for retail and brokerage houses, exchanges, and buy-side firms. The company focuses on trading platforms and brokerage automation, complex software development projects, market data products, and IT consulting services. 

Job Description

We are looking for a Senior Java engineer to develop high-performance distributed exchange systems. The exchange must seamlessly handle tens of thousands of trade requests per second, with processing time for each order in the microsecond range. In addition to receiving and processing orders, the system provides a variety of high-performance APIs, calculates and checks risks, integrates with third-party systems, reliably saves all events and provides reports and analytics, and publishes market data.

For performance-critical components, we cannot afford to use databases, transaction managers, or even write to disk. Even the shortest garbage collection is undesirable. In less critical services, you can be more relaxed, but the code must still be neat, well-designed, and well-maintained.

We work using Kanban, with a small team, Git, mandatory code reviews, and an informal atmosphere. We write both unit and integration tests. All ideas are welcome and encouraged.

Doesn't it sound like a great place to work?

Qualifications

We expect the Middle/Senior Java Developer to have: 

  • Excellent knowledge of basic data structures and algorithms,
  • Solid understanding of J2SE aka "core Java" toolkit. With us, you are unlikely to be able to apply the knowledge of complex frameworks (yes, we are talking about you, Hibernate, and about you, Spring), but you will work with the network, shared memory, bits, files, and multithreading,
  • Experience and interest in "low-level" Java development. The most productive components are designed with mechanical sympathy in mind and should not produce garbage,
  • The ability to profile, write benchmarks, analyze logs and dumps, put forward, validate, and refute hypotheses about the behavior of the program in real conditions,
  • Interest (or better - experience) in the design and use of distributed systems. CAP theorem, network protocols, event sourcing, consensus, replication, partitioning, etc.,
  • Ability to design, implement and use REST API,
  • Proficiency in English sufficient to read and write technical documentation.

Nice-to-have skills: 

  • Experience with databases (both SQL and NoSQL),
  • Design and performance optimization, with a deep understanding of how things work under the hood,
  • Experience with ZooKeeper, etcd, Consul,
  • Experience with Docker and its orchestration tools,
  • Experience with Linux, especially in fine-tuning it,
  • Experience with high-performance messaging systems and protocols such as Aeron, TIBCO, Informatica, etc.,
  • Understanding of exchange financial markets,
  • Experience with financial protocols (FIX).
