What is a software engineer startup?

A Software Engineer Startup job involves developing, testing, and maintaining software in a fast-paced, early-stage company. Engineers in startups often wear multiple hats, working on both backend and frontend development, infrastructure, and sometimes even product decisions. The role requires adaptability, problem-solving skills, and the ability to work with limited resources. Unlike larger companies, startup engineers may need to prototype quickly, iterate based on user feedback, and contribute to the overall growth strategy. This position is ideal for those who enjoy dynamic environments and taking ownership of projects.

What are the key skills and qualifications needed to thrive in the software engineer startup position, and why are they important?

To thrive as a Software Engineer in a startup environment, you need solid programming skills, a problem-solving mindset, and a degree in computer science or related experience. Familiarity with agile methodologies, cloud platforms, version control (like Git), and rapid prototyping tools is highly valued, and startup engineers may also benefit from exposure to full-stack development. Adaptability, effective communication, and the ability to work independently in uncertain environments are standout soft skills. These competencies enable engineers to rapidly iterate on products, effectively collaborate across small teams, and contribute to the dynamic demands of a growing company.

What can I expect from the daily work environment as a software engineer at a startup?

Working as a Software Engineer at a startup typically means you'll be part of a small, agile team where roles and responsibilities can shift quickly based on company needs. You'll often participate in daily stand-ups, collaborate closely with founders or product leads, and have the opportunity to contribute ideas beyond your core coding tasks. The pace is usually fast, and you'll likely wear multiple hats, working on everything from prototyping new features to troubleshooting production issues. This hands-on, collaborative atmosphere provides excellent opportunities for skill growth, creative problem-solving, and making a visible impact on the company's direction.

Senior Software Engineer

Alloy Enterprises

Burlington, MA • On-site

$125K - $160K/yr

Full-time

Re-posted 12 hours ago

Job description

Cooling performance limits high-power computing, semi-conductor fab, cell networks, photonics, power electronics, and most of our digital world. Alloy Enterprises enables customers to break through these constraints with novel complex metal components that dramatically improve heat dissipation in high-performance systems. Alloy's patented Stack Forging™ process enables complex micro-geometries, resulting in single-piece, leak-tight parts that deliver superior cooling performance, lower pressure drops, and exceptional reliability. Founded in 2020, Alloy is a 60-person hardtech startup that has raised over $50M in capital and is shipping components to customers manufacturing servers, lasers, semiconductor equipment, and defense systems.
About the role
We are looking for a Senior Software Developer who will work with an interdisciplinary team to design and implement Alloy's software throughout its lifecycle. You are an expert C++ developer with experience in geometry-centric software, and have an informed point of view on how software is architected while being able to right-size solutions to an existing codebase. You will work to define, design, develop, implement, and maintain Alloy's software suite. Your end-users are in the building, and there are many opportunities for rich collaboration. Strong communication, flexibility, and the desire to "wear many hats" will all be essential for your success here. You will be joining a team of startup veterans who are no strangers to hard tech.
This role generally requires 4 days onsite per week.
Responsibilities
*Responsibilities are subject to change based on shifting business needs
  • Co-design a software suite that runs end-to-end workflows for Alloy's novel Stack ForgingTM manufacturing process.
  • Develop 3D algorithms to improve part accuracy and simplify support removal
  • Take products and features from requirements definition to proof-of-concept prototypes to production code
  • Develop 2D motion and path planning algorithms to improve the throughput of Alloy's Construct machine
  • Collaborate in the team's agile development process
  • Provide feedback and improve the team's code quality
  • Work with external designers and developers as needed

What you'll bring
  • Comfort in a fast-paced startup environment with a bias towards action
  • Able to balance long-term strategic thinking with short-term focus on details
  • 3+ years of experience with computational geometry or an adjacent field (i.e. CAD, Simulation, Graphics, CAM, etc.)
  • Strong experience in C++: object oriented design and development, design patterns, and other software development methodologies
  • 4-year degree in fields such as Computer Science, Computer Engineering, Mathematics, or Physics (or equivalent experience)
  • 5+ years of industry experience building, testing, and shipping high quality code

Preferred skills:
  • Comfortable developing for both back-end and front-end applications, and preferably worked with embedded Linux environments
  • Experience architecting software systems considering customer workflow and process dataflow
  • Have broad applications experience and have 'shipped code'
  • Worked in a relevant field such as additive manufacturing, industrial inspection, 3D CAD tools, motion planning or control
  • Experience developing in an agile production code environment

*Pay Range: $125,000-160,000 annually dependent on experience, qualifications, and education level
Additional requirements
This position will require access to information subject to control under U.S. export control laws and regulations, including the Export Administration Regulations ("EAR") and International Traffic in Arms Regulations ("ITAR").
