What is a software engineer contract?

Software engineer contracts are agreements where software engineers are hired on a temporary basis to work on specific projects or for a set period of time, rather than as permanent employees. Contractors often work for multiple clients, are paid hourly or per project, and may have more flexible schedules. These contracts outline the scope of work, compensation, deadlines, and other terms. Contract software engineers are responsible for delivering quality code and meeting the requirements set by the client or organization. This working arrangement can offer more autonomy, but also less job security and benefits compared to full-time employment.

What are the key skills and qualifications needed to thrive as a software engineer contract?

To thrive as a Software Engineer Contract, you need strong programming skills, a solid understanding of software development methodologies, and a relevant degree or proven experience in computer science or related fields. Familiarity with source control systems (e.g., Git), cloud platforms, and proficiency in languages or frameworks required by the contract are crucial, as are any certifications in areas like AWS or Agile methodologies. Excellent problem-solving, adaptability, and communication skills help you quickly integrate with new teams and deliver results in diverse environments. These skills ensure you can efficiently contribute to projects, meet client expectations, and maintain professional flexibility across various assignments.

AspectSoftware Engineer ContractSoftware Engineer Full-Time

In summary, Software Engineer Contract roles are temporary positions focused on specific projects, often with fewer benefits, while Software Engineer Full-Time roles offer permanent employment with comprehensive benefits. Both roles require similar skills and credentials but differ mainly in employment stability and perks.

What are some common challenges faced by software engineers working on contract positions, and how can they be managed?

Software engineers on contract often face challenges such as quickly adapting to new codebases, understanding diverse team workflows, and managing changing project scopes. It's important to proactively communicate with team members, clarify project requirements early on, and stay organized to meet tight deadlines. Additionally, maintaining a strong personal workflow and being open to feedback can help contract engineers integrate more smoothly and deliver high-quality results within limited timeframes.

Job description

About Commonwealth Fusion Systems: 

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent, and new technologies, we're designing and building commercially viable fusion power plants. And we're working with policymakers and suppliers to build the energy industry of the future. 

We're in the best position to make it happen. Since 2018, we've raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world.

Now we're looking for more thinkers, doers, builders, and makers to join us. People who'll bring new perspectives, solve tough problems, and thrive as part of a team. 

If that's you and this role fits, we want to hear from you.

Join the power movement as an Assembly Process Engineer - Contract
 
As a SPARC Assembly Process Engineer, you will help create, define, instruct, and assist in managing the process by which we assemble the SPARC tokamak device. This will include collaborating with the system design teams on the sequence and key steps, organizing and designating how the various sub-assemblies will come together to create the larger whole, identifying assembly methods and tools required, and then writing these steps into work instruction packets for use by the assembly technicians to use in the field. You will work closely and collaborate with the other SPARC teams to find the most efficient, creative, cost-effective, and safest way to assemble each part of the tokamak. You will guide and organize how the giant parts of this multi-million pound "Swiss-watch" come together! This work is conducted within a multi-disciplinary team of physicists and engineers as part of collaborative sponsored research projects at the MIT Plasma Science and Fusion Center and within CFS.
What you'll do:
  • Develop plans and work instructions for the successful handling, manipulation, guidance, and general integration of complex, novel, and unique assemblies that make up the SPARC sub-systems
  • Assist a lead field engineer in finalizing the strategy for each assembly step - this requires collaboration with the system teams to find the optimum assembly steps, methods, strategies, safety measures, specifications, custom and off-the-shelf tooling, and other details
  • Develop a working knowledge of CFS ERP and MES systems and ensure that part traceability is integrated into the work instruction steps and throughout the part assembly process
  • Utilize problem solving ability and communication skills when non-conformances and challenges arise in the assembly process
  • Within the work instruction development, ensure tool and personnel access is available as required for system assembly steps
  • Be responsible for the plans of part movement at each step and checking that there are no interferences with other systems during movement and part placement
  • Be responsible for construction of the assembly work instruction packets for all SPARC sub-assemblies, and the incorporation of them into the assembly work orders to create the optimum assembly and testing sequence
  • Provide assistance in development and improvement of the work instruction packet and work order creation process to increase standardization, efficiency, safety, clarity, and overall good communication of the instructions for the success of the assembly process
  • Participate in collaborative work with the assembly engineers, tooling engineers, designers, coordinators, as well as direct personnel performing the Tokamak Assembly during on-site work
What we're looking for:
  • High School Diploma
  • At least 5 years technical experience in the integration of complex and large mechanical structures (e.g. aerospace, chemical) and experience in work instruction packet creation
  • Bachelor's or associate degree in a related field, metrology, high-vacuum projects and processes, experience with manufacturing management software, NX, large Component (>10 Ton) lifting experience
  • Exceptional attention to detail
  • Safety conscious and proactive
  • An ability to clearly express and critique ideas
  • An aptitude to use data to drive decisions
  • An emphasis on elegance and simplicity over complexity
  • The ability to thrive in fast-paced, dynamic environments
  • A drive toward commercially viable solutions
  • Values that align with our company's values of integrity, execution, impact, and self-critique
Must-have requirements:
  • Ability to occasionally lift up to 50 lbs
  • Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
  • Perform activities such as typing, standing, or sitting for extended periods of time
$45 - $62 an hour
This is a contract position.
#LI-Onsite
#CFS-NE

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we're eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.

We value diversity deeply and are proud to be an equal opportunity employer by choice. We consider all qualified applicants equally, regardless of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law.

This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, "Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.
