Job description

As a Senior Software Engineer, you will be a key contributor to the design, development, and optimization of high-performance, distributed software systems that power our next‑generation robotic and automation platforms. We are specifically looking for engineers with hands‑on Erlang experience, who can help us build robust, fault‑tolerant systems at scale.

You will work in close collaboration with product managers, system architects, and cross‑functional engineering teams to build solutions that are critical to warehouse automation, robotics orchestration, and real‑time decision‑making systems.

Responsibilities

• Design and implement core modules in Erlang to build scalable, distributed systems.

• Lead development of critical product features and solve complex system‑level challenges.

• Collaborate with architects to define low‑level design and contribute to the technical roadmap.

• Refactor and optimize existing algorithms and services for improved performance and reliability.

• Review code, provide technical mentorship, and promote best coding practices within the team.

• Use simulations and testing to validate system behavior and performance at scale.

Requirements

• 3+ years of professional software development experience with strong problem‑solving skills.
• Hands‑on experience in Erlang preferred and a strong understanding of its concurrency model (processes, message passing, supervision trees).
  • or heavy experience with any of the following programming languages: Erlang, Elixir, Gleam, Pony, Akka (Scala), Haskell
• Exposure to building and maintaining distributed, high‑availability systems.
• Experience with microservices architecture and REST‑based APIs.
• Solid knowledge of RDBMS/SQL and experience working with databases in production environments.
• Understanding of software design principles, object‑oriented programming, and system design patterns.
• Familiarity with version control systems (Git or similar).
• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field from a reputed institute.
• Strong analytical and debugging skills with the ability to work in a fast‑paced environment.
• Clear, concise communication skills, with the ability to explain complex technical concepts to diverse stakeholders.
• Work within a distributed systems environment — candidates must have prior experience in distributed or high‑throughput operational systems (e.g., warehousing, e-commerce, distribution hubs, Amazon‑style fulfillment environments).

Nice to Have

• Background in real‑time systems, telecom‑grade architectures, or robotic platforms.
• Exposure to CI/CD pipelines and containerized deployments (Docker, Kubernetes, etc.).

Benefits

• Comprehensive health and dental insurance
• Retirement plans like a 401K
• Time off benefits such as paid time off and maternity/paternity leave.
• They also offer work‑life balance support through flexible hours and hybrid work options, alongside professional growth opportunities in the form of training programs and job training.
