BLAKFRAME careers

BLAKFRAME LTD is a systems engineering firm registered in England and Wales (Company No. 16726125). The firm works where software correctness must hold for all inputs, not most of them — and where the failure modes are memory corruption, undefined behaviour, and divergence between specification and execution. Its work is twofold: the development of BLAKHOLE, the firm's principal engineering effort, and an active security research practice on low-level and cryptographic software, which is the firm's main source of income. The firm operates business-to-business; it offers no consumer products and holds no client funds.

BLAKHOLE is developed in-house and is not licensed, hosted, or sold as a product. The firm does not publish its architecture, implementation, or deployment details. The firm maintains an active security research practice on low-level and cryptographic software: resource exhaustion in serialization routines, unsafe handling in critical execution paths, divergence between protocol specification and implementation, and defects in cryptographic protocol implementations. Findings are reported to the affected maintainers under coordinated disclosure. The firm does not develop offensive capabilities, does not sell exploits, and does not provide surveillance or interception services.

Both lines of work are conducted in-house and reinforce each other: the research practice examines how systems fail, and the engineering applies that knowledge to how systems are built. BLAKFRAME is self-funded, with income from the firm's security work. The firm holds no external investors and is not seeking investment. The firm operates business-to-business, on a principal-to-principal basis, under separate agreements per engagement.
