Garbage Collectors Jobs (NOW HIRING)

Tangram Flex is seeking a Software Engineer with Language Development Experience to help design, develop, and optimize core interpreter/transpiler infrastructure and language toolchains. In this role, you will work at the intersection of programming language design, hardware architecture, and systems engineering by translating high-level abstractions into high-performance, production-ready machine code. Whether you are optimizing intermediate representations (IR), building custom front-ends/back-ends, or tuning domain-specific code generators (e.g., native compilers, DSLs, or transpilers).

Candidates should possess a solid technical skillset coupled with the drive to pursue deep understanding and the capability to work independently with minimal supervision. You will collaborate closely with software engineers, systems engineers, and defense stakeholders throughout the entire program lifecycle to turn design intent into executable, verified software reality.

What We Do: Our team and products provide solutions to enable innovators to design, develop, verify, and advance critical systems, while accelerating innovation that advances our nation's security. By accelerating delivery of critical systems, Tangram is transforming the way our nation solves complex software challenges.

JOB RESPONSIBILITIES/

• Software Development & Implementation: Read, and write high-quality, efficient code in relevant languages, such as C, C++, Rust, and/or Python
• Interpreter & Transpiler Development: Design, implement, and maintain interpreter components (front-end parsers, type checkers, optimization passes, and back-end code generators).
• Performance Tuning: Analyze generated assembly or IR, profile code execution, and implement IR-level and target-specific optimizations (vectorization, instruction scheduling, register allocation, auto-parallelization).
• Toolchain & Runtime Infrastructure: Support build systems, linkers, debuggers, static analysis tools, runtime systems, and garbage collectors/allocators.
• Architecture Support: Collaborate with hardware/systems engineering teams to define, target, and optimize for new Instruction Set Architectures (ISAs) or specialized hardware accelerators (GPUs, NPUs, TPUs, FPGAs).
• Language Design & Semantics: Contribute to the specification and implementation of domain-specific language (DSL) features or language extensions.
• Code Quality & Testing: Write comprehensive unit, regression, and benchmark test suites to ensure interpreter correctness, stability, and performance trackability.

• Collaboration & Communication: Partner cross-functionally with systems engineers and product teams to translate model characteristics and system requirements into test plans, and articulate technical findings clearly to both business and technical users.

DESIRED SKILLS & EXPERIENCE/

Required Skills:

• Bachelor's Degree in Computer Engineering, Computer Science, Electrical Engineering, Systems Engineering, or an equivalent technical field.
• Minimum of 3+ years of working on compilers, interpreters, or transpilers for parallel architectures.
• Ability to obtain or possess a current/or recent U.S. Government Security (DoW) Clearance. U.S. citizenship is required to obtain clearance.
• Programming languages: Systems programming language experience, such as C, C++, Rust, etc. Includes raw memory management, performance optimization, and modern best practices.
• Interpreter Fundamentals: Deep understanding of modern interpreter and/or transpiler architecture (lexing/parsing, ASTs, intermediate representations, control/data-flow analysis, and optimization passes).
• Target Architectures: Solid understanding of computer architectures (x86, ARM, RISC-V) and assembly language.
• Proven experience creating or extending language grammars.
• Travel required occasionally for customer support and presentations
• Work is performed in Dayton, Ohio
  

Preferred Skills:

• Experience with production compiler frameworks (e.g., LLVM, GCC, MLIR, Cranelift, or NVVM).
• Experience with FPGA configuration & programming logic.
• Experience with program analysis, static & dynamic code analyzers, and/or formal verification.
• Active contributions to an open-source compiler, interpreter, transpiler, or other language infrastructure projects.

Physical Requirements:

• Ability to travel by air, car, or other transportation methods
• Prolonged periods of sitting at a desk and working on a computer (up to 8 hours/day)
• Ability to lift and carry lightweight items (e.g., laptops, demo equipment, marketing materials) up to 25 lbs.
• Frequent use of hands and fingers for typing, using a mouse, writing, and handling equipment.
• Visual acuity to read detailed technical documents, view computer screens, and operate software systems
• Auditory ability to participate in meetings, customer demos, and conference calls, including in potentially noisy environments (e.g., trade shows or military facilities)
• Mobility to move between office spaces, customer sites, conference venues, and manufacturing or lab environments
• Flexibility to adapt to varying work environments (e.g., corporate offices, government buildings, industrial or lab spaces)

We are committed to staying rooted in our core value of Team First. For that reason, we've designed a highly competitive benefits program and supportive work environment to engage employees and their families.

• Hybrid work options
• Flexible Working Hours, 10 paid holidays, and generous Paid Time Off
• Employer Paid Medical, Dental, Vision and Short and Long Term Disability Insurance
• Access to group rating plans for Life Insurance
• Employer contribution to Health Savings Account
• Competitive 401K employer match
• A vibrant engineering culture that fosters transparency, collaboration, and continuous professional growth via internal tech community events (Lightning Talks, Integration Events).
