We are staffing developers to help a large hedge fund replace a commercial tick database (OneTick) with kdb+ for real-time market data and Apache Iceberg for end-of-day history. A Python service layer, exposed over gRPC and Arrow Flight, will sit in front of both stores. The fund's existing .NET wrapper stays as the client-facing interface and is re-backed by the new services.
The work runs in parallel with the current system: build the new stack, reconcile it against OneTick, then cut consumers over one at a time. This developer will own the .NET side of the migration, working alongside our architect and the client's engineering team.
Responsibilities:
6+ years of C# and modern .NET (6 or later).
Production experience with gRPC in .NET (Grpc.Net.Client, protobuf code generation, streaming calls).
Hands-on use of Apache Arrow in .NET (Apache.Arrow package) or another columnar data format.
Strong handling of high-volume data: memory allocation, Span/Memory, streaming, async.
Care with timestamp precision, time zones and numeric types.
Nice to have:
Arrow Flight in any language.
kdb+ C# client experience (csharpkdb, qSharp) or basic q.
Prior work wrapping a market data or tick database API (OneTick, kdb+, Bloomberg, Refinitiv).
QUALIFICATION STANDARDS
Work Experience:
Market data work at a hedge fund, bank, broker or trading technology vendor.

Understanding of the difference between exchange, vendor and capture timestamps, and why it matters.
