What does a Full Time Software Engineer do at a startup?

A Full Time Software Engineer at a startup is responsible for designing, coding, testing, and maintaining software applications or systems that are central to the company’s product or service. In a startup environment, engineers often work on a wide range of tasks, from building new features and fixing bugs to collaborating on system architecture and deployment. They typically work closely with founders, designers, and other team members, adapting quickly to changing requirements and helping the company scale. The fast-paced and dynamic nature of startups often means engineers have significant ownership and impact on the final product.

What are the key skills and qualifications needed to thrive as a Full Time Software Engineer at a startup, and why are they important?

To thrive as a Full Time Software Engineer at a startup, you need strong programming skills, problem-solving abilities, and a degree in computer science or related field. Familiarity with modern development frameworks, cloud platforms, version control systems like Git, and agile methodologies is typically required. Adaptability, proactive communication, and a collaborative mindset help you excel in a fast-paced, evolving environment. These skills are crucial for quickly building, iterating, and scaling products while contributing effectively to a small, dynamic team.

What unique challenges might a Full Time Software Engineer face when working at a startup compared to a larger company?

As a Full Time Software Engineer at a startup, you may encounter rapidly changing priorities and a fast-paced environment where flexibility is key. Unlike larger companies with specialized teams, you’ll likely wear multiple hats, contributing to various parts of the tech stack and sometimes assisting with non-coding tasks. This dynamic can be both challenging and rewarding, offering opportunities to have a direct impact on the product and company growth. Close collaboration with founders and cross-functional teams is typical, fostering a culture of innovation and learning.

Altamira Technologies Corp.

Warrenton, VA

$100K - $150K/yr

Full-time

Re-posted 20 days ago

Job description

Altamira Technologies has a long and successful history providing innovative solutions throughout the U.S. National Security community. Altamira serves the defense, intelligence and homeland security communities worldwide by focusing on creating innovative solutions leveraging common standards in architecture, data and security. Altamira believes that our people and the culture of our company differentiate us from other companies.
Position: Software Engineer
Location: Warrenton, VA
Position Description:
We are seeking a Software Engineer who thrives on developing high-throughput data, low-latency code, and complex algorithm implementation. The available position moves beyond high-level application code, focusing on the intersection of systems programming, digital signal processing, and real-time data orchestration. As a Software Engineer at Altamira, you will design and build the software engines that power our sensing and communication platforms. You will be responsible for the full software lifecycle - architecting data pipelines, implementing algorithms in code, and developing robust APIs. You must be comfortable working in a Linux-centric environment where performance optimization and memory management are critical.
Key Responsibilities:
High-Performance Development: Architect and maintain mission-critical applications using C++ for performance-intensive processing and Python for prototyping algorithms, systems logic, data manipulation, and rapid feature deployment.
Data Orchestration: Develop software to handle high-rate data streams over UDP/TCP, ensuring packet integrity and low-latency transfer between hardware and software.
Automation & Tooling: Create Python-based tools for automated testing, signal simulation, and benchmarking performance of the software stack. Support GitLab CI integration for automated build and deployments.
Software-Defined DSP: Translate complex mathematical algorithms (FFTs, FIR filters, DDC, spectral estimation) into efficient, scalable Digital Signal Processing (DSP) software implementations.
Agile Collaboration: Lead and participate in code reviews, utilize Git and Jira development productivity tools, support complex software releases in a collaborative environment.
Must-Have Qualifications and Experience:
Software Engineering: Professional software development experience with an emphasis on C/C++ and Python.
Linux Systems: Proficiency with multi-threading, Inter-Process Communication (IPC), and network socket programming.
Frameworks: Experience with X-Midas or similar signal processing frameworks (e.g., GNU Radio, REDHAWK).
Mathematical Computing: Experience implementing mathematical / scientific algorithms in code.
Software Best Practices: Strong rasp of Object-Oriented Design (OOD), design patterns, and modern DevOps/CI/CD.
Nice-To-Have Qualifications and Experience:
CUDA or OpenCL: Experience using GPU-accelerated signal processing.
Docker or Podman: Knowledge of containerization and orchestration for deploying processing nodes.
Signals: Familiarity with signal characteristics (pulsed/CW radar, modulations) and algorithms (FFTs, FIR filters, DDC).
Digital Signal Processing (DSP): Understanding of concepts and software implementation (NumPy, SciPy, or FFTW).
Applications: Background in Electronic Warfare (EW) or SIGINT (COMINT, ELINT) application areas.
Clearance Requirements:
Must be a U.S. citizen and be able to obtain up to a TS/SCI clearance.
The anticipated salary range for this position is $100,000 to $150,000. Actual compensation will be determined based on several factors, including, but not limited to, the scope of the position, relevant experience, education, certifications, internal equity, customer contractual requirements, security clearance requirements, and other legitimate business considerations.
Employment Type: Full Time
