Senior Software Engineer, Radio Frequency Job at Tangram Flex in Dayton

We are seeking a Senior Software Engineer with Radio Frequency (RF) or Digital Signal Processing (DSP) experience to join our team. This is a hands‑on technical role focused on building real‑world RF sensing systems. You will operate as a key contributor across multiple programs, working at the intersection of embedded systems, RF environments, and mission‑driven software, collaborating closely with DSP engineers, hardware designers, and modeling and simulation experts. This position will require Dayton, Ohio as a work location.

This role is ideal for someone who understands how Electronic Warfare (EW) systems function in practice and can translate that into robust, deployable software.

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

Design, develop, and maintain embedded software for EW and RF sensing systems

Investigate innovative PA architectures, calibration algorithms, processing structures for performance enhancement

Architect HW/FW/SW partitioning of various calibrations for area and time efficiency

Translate EW concepts (EA, ES, EP) into functional software capabilities

Own and contribute to core portions of the embedded codebase, becoming a subject matter expert

Collaborate with DSP, FPGA, and hardware teams to integrate algorithms into real‑time systems

Work with digital designers to realize these methods with power and area efficient digital implementations

Implement system models of the analog front‑end design, impairments and come up with right controls and calibrations in C and MATLAB for optimal system performances

Develop prototypes and operational capabilities, not just simulations

Participate in lab and field testing, including data collection, analysis, and system validation

Contribute to and improve software engineering practices, tooling, and architecture

Support integration of third‑party tools, models, and open‑source frameworks

Provide technical support to clients during and after the implementation of solutions

Support and author proposals, white papers and other opportunity‑shaping activities

Consistent interaction with both Engineering Leadership and Product Management team to help inform roadmap and priorities

Identifying opportunities for new business and developing proposals to win new clients

Strong proficiency in C/C++, MATLAB, Python used for algorithm development, modeling, and simulation

Experience with at least one modern systems language: Rust, Go, or Zig

Experience developing embedded or low‑level software systems

Experience with software‑defined radios (SDRs) and RF data pipelines

Working knowledge of electronic warfare concepts and basic understanding of RF and analog components/modules

Familiarity with digital signal processing concepts sufficient to integrate and implement

Experience with Linux‑based development environments

Ability to work independently and contribute in a highly collaborative, cross‑functional team

Strong communication skills and ability to operate in mission‑focused environments

Work location is Dayton, Ohio

Travel up to 25%

Master’s degree with 3+ years of experience

Familiarity with GNU Radio or similar frameworks. Understand communication theories and signal processing related algorithms design such as timing recovery, signal estimation and detection, automatic gain control, channel estimation, equalization, coding theory

Experience integrating DSP algorithms into real‑time systems

Exposure to FPGA/firmware interfaces (VHDL/Verilog not required, but helpful)

Experience with modeling and simulation environments

Background in SIGINT, ELINT, or radar systems

Understanding and/or interest in Open Architectures and relevant DoD standards such as OMS or FACE

Familiarity or interest with Software Defined Radios (e.g., GNURadio, REDHAWK), digital signal processing (DSP), or FPGA design and programming (e.g., VHDL, Simulink, LabView)

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)
